Julez: /* How To Build It? */

==EHP - Emotion Heartbeat Project==
 
The "Emotion Heartbeat Project" is a project that will collect my heartrate as a datatype. This data will be displayed in a visual way with diagrams and create an emotional diary out of that. With an increased heartrate the heartrate monitor will ask for the cause of it to differentiate between positive and negative stress or sports activities.
 
 

===First Ideas And Thoughts===

File:4_page4.jpg|Collected Heartbeat-Data Within 1 Week
File:5_page5.jpg|Heartrate Diagrams
</gallery>
 
One of my first ideas was to connect the heartrate monitor with headphones that would calm down my increased heartrate with music and vibrating sensors at my neck; showing picture 3 and 5. The decision diagram displays how this should work.
But within this semester I will just build up the heartrate monitor itself.

Picture 6 and 7 are showing the result of 1 week of collecting heartrate data. I counted my heartbeat within 1 minute manually 4 times a day for 1 week. Pic 6 shows a diagram displaying the whole week at a glance; Pic 7 shows the diagrams of each day in particular. (Unfortunately I couldn't get it work with a consistent scale for the heartrate.)

Inspired by diverse links and Youtube videos the very first try to build it was to use IR Emitter and Detector. It didn't work that well: the sensors are pretty sensitive for moving action and the signal at processing was very faint.
So I decided to try it again with an amplifier to get a stronger signal of my heartbeat.
 
To amplify the signal I used a low voltage op-amp LM358N.
The images of the third gallery show the circuit, schematic and processing screen result.
 
The Data Logger Shield for the Arduino board is directly plugged on the top of it and will save the collected data to a SD card.

THE EKG SENSOR
 
 
The selfmade sensor with the IR Emitter and Detector is very sensitive for any motion and movements of the finger being measured. So I tried out a EKG Sensor which displayed a higher resolution of the heartbeat on processing. There are 3 electrodes patches placed on the skin: One on the right wrist for the reference, one on right elbow for the negative alligator clip and one on the left elbow for the positive clip. The EKG Sensor is connected with the Arduino to Ground, 5V and Analog Input A0. The heartbeat is displayed with Processing.

This was a pretty good thing to test but unfortunately it wasn't convenient for a design to wear it every day and take everywhere I go. In cause of that and diverse failed trys to make a sensor by my own, I decided to buy a device.
 
 

===Realization===

This device is a Data-Logger which goes with a chest strap: the chest strap measures the heartrate and the Data-Logger saves it every 2nd or each second. The saved values are collected in CSV-files which can be displayed with the program of the Data-Logger, shown with the images below.

File:oregon-data-logger_2_markiert.jpg|interface data-logger program
File:oregon-data-logger_3.jpg|interface data-logger program
</gallery>
 
The program of the Data-Logger to visualize the collected data is a pretty good way to have a quick view to the results of the measurements. But the CSV-files need to be cleaned of extreme and zero values which were saved in cause of disturbances between the connection of the chest strap and the Data-Logger. The following images below show possible interface designs to display the collected heart rate and to analyse the results.

The project and the two devices were a pretty good way for getting started with the idea of heartbeat, collecting emotional data. But there are still some Things which need to be improved:

This was a pretty good thing to test but unfortunately it wasn't convenient for a design to wear it every day and take everywhere I go. In cause of that and diverse failed trys to make a sensor by my own, I decided to buy a device.
 
 

===Realization===

This device is a Data-Logger which goes with a chest strap: the chest strap measures the heartrate and the Data-Logger saves it every 2nd or each second. The saved values are collected in CSV-files which can be displayed with the program of the Data-Logger, shown with the images below.

File:oregon-data-logger_3.jpg|interface data-logger program
</gallery>
 
The program of the Data-Logger to visualize the collected data is a pretty good way to have a quick view to the results of the measurements. But the CSV-files need to be cleaned of extreme and zero values which were saved in cause of disturbances between the connection of the chest strap and the Data-Logger. The following images below show possible interface designs to display the collected heart rate and to analyse the results.

Inspired by diverse links and Youtube videos the very first try to build it was to use IR Emitter and Detector. It didn't work that well: the sensors are pretty sensitive for moving action and the signal at processing was very faint.

To amplify the signal I used a low voltage op-amp LM358N.
The images of the third gallery show the circuit, schematic and processing screen result.

The selfmade sensor with the IR Emitter and Detector is very sensitive for any motion and movements of the finger being measured. So I tried out a EKG Sensor which displayed a higher resolution of the heartbeat on processing. There are 3 electrodes patches placed on the skin: One on the right wrist for the reference, one on right elbow for the negative alligator clip and one on the left elbow for the positive clip. The EKG Sensor is connected with the Arduino to Ground, 5V and Analog Input A0. The heartbeat is displayed with Processing.

This was a pretty good thing to test but unfortunately it wasn't convenient for a design to wear it every day and take everywhere I go. In cause of that and diverse failed trys to make a sensor by my own, I decided to buy a device.
 
 

===Realization===

This device is a Data-Logger which goes with a chest strap: the chest strap measures the heartrate and the Data-Logger saves it every 2nd or each second. The saved values are collected in CSV-files which can be displayed with the program of the Data-Logger, shown with the images below.

The program of the Data-Logger to visualize the collected data is a pretty good way to have a quick view to the results of the measurements. But the CSV-files need to be cleaned of extreme and zero values which were saved in cause of disturbances between the connection of the chest strap and the Data-Logger. The following images below show possible interface designs to display the collected heart rate and to analyse the results.

The project and the two devices were a pretty good way for getting started with the idea of heartbeat, collecting emotional data. But there are still some Things which need to be improved:
As I mentioned the disturbances between the two devices I had to check the Connection between the two devices permanently because in some cases the signal wasn't strong enough and got interrupted through electro magnetic fields. Furthermore ist was very unconvinient and not very comfortable to wear the chest strap the whole time. I wore it every day for two weeks and was pretty stressed out. It may be ok to wear it while doing sports for that short period of time but not in everyday life. Possible could be to make an earclip or to integrate it into a device or a thing you need every day.

To amplify the signal I used a low voltage op-amp LM358N.

The selfmade sensor with the IR Emitter and Detector is very sensitive for any motion and movements of the finger being measured. So I tried out a EKG Sensor which displayed a higher resolution of the heartbeat on processing. There are 3 electrodes patches placed on the skin: One on the right wrist for the reference, one on right elbow for the negative alligator clip and one on the left elbow for the positive clip. The EKG Sensor is connected with the Arduino to Ground, 5V and Analog Input A0. The heartbeat is displayed with Processing.

To amplify the signal I used a low voltage op-amp LM358N.
The images of the third gallery show the circuit, schematic and processing screen result.

The Data Logger Shield for the Arduino board is directly plugged on the top of it and will save the collected data to a SD card.

The selfmade sensor with the IR Emitter and Detector is very sensitive for any motion and movements of the finger being measured. So I tried out a EKG Sensor which displayed a higher resolution of the heartbeat on processing. There are 3 electrodes patches placed on the skin: One on the right wrist for the reference, one on right elbow for the negative alligator clip and one on the left elbow for the positive clip. The EKG Sensor is connected with the Arduino to Ground, 5V and Analog Input A0. The heartbeat is displayed with Processing.

This was a pretty good thing to test but unfortunately it wasn't convenient for a design to wear it every day and take everywhere I go. In cause of that and diverse failed trys to make a sensor by my own, I decided to buy a device.
 
 

===Realization===

This device is a Data-Logger which goes with a chest strap: the chest strap measures the heartrate and the Data-Logger saves it every 2nd or each second. The saved values are collected in CSV-files which can be displayed with the program of the Data-Logger, shown with the images below.

File:oregon-data-logger_2_markiert.jpg|interface data-logger program
File:oregon-data-logger_3.jpg|interface data-logger program
</gallery>
 
The program of the Data-Logger to visualize the collected data is a pretty good way to have a quick view to the results of the measurements. But the CSV-files need to be cleaned of extreme and zero values which were saved in cause of disturbances between the connection of the chest strap and the Data-Logger. The following images below show possible interface designs to display the collected heart rate and to analyse the results.

====Alternatives For Visualization====

</gallery>
 
 
The project and the two devices were a pretty good way for getting started with the idea of heartbeat, collecting emotional data. But there are still some Things which need to be improved:
As I mentioned the disturbances between the two devices I had to check the Connection between the two devices permanently because in some cases the signal wasn't strong enough and got interrupted through electro magnetic fields. Furthermore ist was very unconvinient and not very comfortable to wear the chest strap the whole time. I wore it every day for two weeks and was pretty stressed out. It may be ok to wear it while doing sports for that short period of time but not in everyday life. Possible could be to make an earclip or to integrate it into a device or a thing you need every day.

Im Rahmen der Kettenreaktion folgt mein Projekt nach Philipps:
 
Ich fange die Kugel, die von Philipps Projekt ausgelöst wird. Durch die Muskelkontraktion in meinen Armen, vom Fangen der Kugel, wird ein Impuls vom EKG-Sensor ans Arduinoboard gesendet, welches die Ventilatoren aktiviert. Durch den entstehenden Wind wird das Auto die Rampe runter geweht. Dieses trifft direkt auf den Piezo an Martins "aRobot" und löst somit den weiteren Verlauf der Kettenreaktion aus.

== Julia: [[Dokumentation]] ==

>Input:
 
Ich fange die Kugel von Philipps Projekt auf wodurch der EKG-Sensor an meinen Armen einen Impuls an den Arduino sendet: durch die Bewegung meines Armes wird ein Schwellenwert überschritten und aktiviert die PC-Lüfter.
Der entstehende Wind weht ein Spielzeugauto kontrolliert nach vorne.
 
Momentan aktiviert ein Schalter die Lüfter. Werde dann noch für die Endpräsentation den EKG-Sensor über das Arduino (ohne Processing dazwischen) mit den Lüftern in Verbindung bringen.
 
 
>Output:
 
Das Spielzeugauto durchfährt die Infrarotschranke von Maschas Projekt.

Magnetische Levitation mit dem Arduino

Utensilien: ein Elektromagnet, ein Hall Sensor und ein Dauermagnet.
Vorgehen: Der Dauermagnet wird mit dem Elektromagneten in einen Schwebezustand versetzt, während der Hall Sensor die Position des Dauermagneten ermittelt, mittels der Stärke des Magnetfeldes. Als einfacher Regelkreis wird dabei die Kraft des Elektromagneten so ausgeglichen, dass der Dauermagnet einen gleichbleibenden Abstand zum Dauermagneten behält und somit im Raum schwebt. Bei dem Dauermagneten kann es sich um eine Kugel handeln, welche von einer vorherigen Apparatur weggeschleudert oder in irgendeiner Form bewegt wird und damit als Output für die nächste Anordnung fungiert.

Input 40 KHz Fernbedienung bzw. IR-Diode >

Geplant ist ein autonomer Roboter. Das Fahrgestell bildet ein Raupenantrieb mit zwei Getriebemotoren. Über einen Motortreiber können sowohl Richtung als auch Geschwindigkeit vom Arduino gesteuert werden.

Der aktuelle Prototyp verfügt über einen IR-Receiver, der Signale von einer Fernbedienung bzw. einer IR-Diode empfangen kann. Darüber werden Steuerbefehle an die Motoren weitergeleitet, so dass die Richtung des Roboters gesteuert werden kann.

Im nächsten Schritt sollen weitere Sensoren hinzugefügt werden, die es dem Roboter ermöglichen einer kontinuierlichen Linie zu folgen.

Als "Start" für den Roboter eignet sich somit ein beliebiges 40 kHz IR-Signal (dafür gibt es eine IR Remote Lib). Alternativ könnte auch ein lichtempfindlicher Sensor integriert oder eine Art Schalter angebracht werden, der bei Kontakt den Roboter startet.

> Output:
Zur Fortführung der Kette kann ich beispielsweise etwas anstoßen oder etwas überfahren (Drucksensor). Es ist auch möglich eine LED mit einer bestimmten Farbe leuchten zu lassen (habe rot, grün, blau, gelb, weiß sowie RGB Leds) oder etwas wegzuziehen (zum Beispiel ein Hölzchen, dass eine Kugel hält usw.)

== Ruben und Judith ==
Prototyp für interaktive Installation mit Arduino, Pure Data, Distanzsensor und Motoren:
 
In unserem Projekt entwickeln wir ein Interface, das als Prototyp für interaktive Installationen dienen soll. Der Besucher löst über einen Distanzsensor Motoren aus und setzt somit Objekte in Bewegung. Das Interface ist so konzipiert, dass die Anschlussmöglichkeiten nicht nur für Motoren genutzt werden können. Somit kann dieser Prototyp für kinetische oder auch akustische Installationen genutzt werden.

Dafür verwendet:
Arduino Uno mit Standard Firmata Code 2.2.
Pduino Objekt von Pure Data Extended Version
Sharp Distanzsensor
Darlington Array ULN 2003A
2 Codensatoren 100 μF, 50V
2 DC Motor, 6V

Als Input muss der Distanzsensor ausgelöst werden; Output bewegte Objekte (Gewicht an Schnur, siehe Foto)

==EHP - Emotion Heartbeat Project==
 
The "Emotion Heartbeat Project" is a project that will collect my heartrate as a datatype. This data will be displayed in a visual way with diagrams and create an emotional diary out of that. With an increased heartrate the heartrate monitor will ask for the cause of it to differentiate between positive and negative stress or sports activities.

One of my first ideas was to connect the heartrate monitor with headphones that would calm down my increased heartrate with music and vibrating sensors at my neck; showing picture 3 and 5. The decision diagram displays how this should work.
But within this semester I will just build up the heartrate monitor itself.

Picture 6 and 7 are showing the result of 1 week of collecting heartrate data. I counted my heartbeat within 1 minute manually 4 times a day for 1 week. Pic 6 shows a diagram displaying the whole week at a glance; Pic 7 shows the diagrams of each day in particular. (Unfortunately I couldn't get it work with a consistent scale for the heartrate.)

Inspired by diverse links and Youtube videos the very first try to build it was to use IR Emitter and Detector. It didn't work that well: the sensors are pretty sensitive for moving action and the signal at processing was very faint.

To amplify the signal I used a low voltage op-amp LM358N.
The images of the third gallery show the circuit, schematic and processing screen result.

The Data Logger Shield for the Arduino board is directly plugged on the top of it and will save the collected data to a SD card.

The selfmade sensor with the IR Emitter and Detector is very sensitive for any motion and movements of the finger being measured. So I tried out a EKG Sensor which displayed a higher resolution of the heartbeat on processing. There are 3 electrodes patches placed on the skin: One on the right wrist for the reference, one on right elbow for the negative alligator clip and one on the left elbow for the positive clip. The EKG Sensor is connected with the Arduino to Ground, 5V and Analog Input A0. The heartbeat is displayed with Processing.

This was a pretty good thing to test but unfortunately it wasn't convenient for a design to wear it every day and take everywhere I go. In cause of that and diverse failed trys to make a sensor by my own, I decided to buy a device.
 
 

===Realization===

This device is a Data-Logger which goes with a chest strap: the chest strap measures the heartrate and the Data-Logger saves it every 2nd or each second. The saved values are collected in CSV-files which can be displayed with the program of the Data-Logger, shown with the images below.

File:oregon-data-logger_2_markiert.jpg|interface data-logger program
File:oregon-data-logger_3.jpg|interface data-logger program
</gallery>
 
The program of the Data-Logger to visualize the collected data is a pretty good way to have a quick view to the results of the measurements. But the CSV-files need to be cleaned of extreme and zero values which were saved in cause of disturbances between the connection of the chest strap and the Data-Logger. The following images below show possible interface designs to display the collected heart rate and to analyse the results.

The project and the two devices were a pretty good way for getting started with the idea of heartbeat, collecting emotional data. But there are still some Things which need to be improved:
As I mentioned the disturbances between the two devices I had to check the Connection between the two devices permanently because in some cases the signal wasn't strong enough and got interrupted through electro magnetic fields. Furthermore ist was very unconvinient and not very comfortable to wear the chest strap the whole time. I wore it every day for two weeks and was pretty stressed out. It may be ok to wear it while doing sports for that short period of time but not in everyday life. Possible could be to make an earclip or to integrate it into a device or a thing you need every day.

To amplify the signal I used a low voltage op-amp LM358N.
The images of the third gallery show the circuit, schematic and processing screen result.

The Data Logger Shield for the Arduino board is directly plugged on the top of it and will save the collected data to a SD card.

The selfmade sensor with the IR Emitter and Detector is very sensitive for any motion and movements of the finger being measured. So I tried out a EKG Sensor which displayed a higher resolution of the heartbeat on processing. There are 3 electrodes patches placed on the skin: One on the right wrist for the reference, one on right elbow for the negative alligator clip and one on the left elbow for the positive clip. The EKG Sensor is connected with the Arduino to Ground, 5V and Analog Input A0. The heartbeat is displayed with Processing.

This was a pretty good thing to test but unfortunately it wasn't convenient for a design to wear it every day and take everywhere I go. In cause of that and diverse failed trys to make a sensor by my own, I decided to buy a device. This device is a Data-Logger which goes with a chest strap: the chest strap measures the heartrate and the Data-Logger saves it every 2nd or each second. The saved values are collected in CSV-files which can be displayed with the program of the Data-Logger, shown with the images below.

File:oregon-data-logger_3.jpg|interface data-logger program
</gallery>
 
The program of the Data-Logger to visualize the collected data is a pretty good way to have a quick view to the results of the measurements. But the CSV-files need to be cleaned of extreme and zero values which were saved in cause of disturbances between the connection of the chest strap and the Data-Logger. The following images below show possible interface designs to display the collected heart rate and to analyse the results.

</gallery>
 
 
The project and the two devices were a pretty good way for getting started with the idea of heartbeat, collecting emotional data. But there are still some Things which need to be improved:
As I mentioned the disturbances between the two devices I had to check the Connection between the two devices permanently because in some cases the signal wasn't strong enough and got interrupted through electro magnetic fields. Furthermore ist was very unconvinient and not very comfortable to wear the chest strap the whole time. I wore it every day for two weeks and was pretty stressed out. It may be ok to wear it whole doing sports for that short period of time but not in everyday life. Possible could be to make an earclip or to integrate it into a device or a thing you need every day.

Magnetische Levitation mit dem Arduino

Utensilien: ein Elektromagnet, ein Hall Sensor und ein Dauermagnet.
Vorgehen: Der Dauermagnet wird mit dem Elektromagneten in einen Schwebezustand versetzt, während der Hall Sensor die Position des Dauermagneten ermittelt, mittels der Stärke des Magnetfeldes. Als einfacher Regelkreis wird dabei die Kraft des Elektromagneten so ausgeglichen, dass der Dauermagnet einen gleichbleibenden Abstand zum Dauermagneten behält und somit im Raum schwebt. Bei dem Dauermagneten kann es sich um eine Kugel handeln, welche von einer vorherigen Apparatur weggeschleudert oder in irgendeiner Form bewegt wird und damit als Output für die nächste Anordnung fungiert.

Input 40 KHz Fernbedienung bzw. IR-Diode >

Geplant ist ein autonomer Roboter. Das Fahrgestell bildet ein Raupenantrieb mit zwei Getriebemotoren. Über einen Motortreiber können sowohl Richtung als auch Geschwindigkeit vom Arduino gesteuert werden.

Der aktuelle Prototyp verfügt über einen IR-Receiver, der Signale von einer Fernbedienung bzw. einer IR-Diode empfangen kann. Darüber werden Steuerbefehle an die Motoren weitergeleitet, so dass die Richtung des Roboters gesteuert werden kann.

Im nächsten Schritt sollen weitere Sensoren hinzugefügt werden, die es dem Roboter ermöglichen einer kontinuierlichen Linie zu folgen.

Als "Start" für den Roboter eignet sich somit ein beliebiges 40 kHz IR-Signal (dafür gibt es eine IR Remote Lib). Alternativ könnte auch ein lichtempfindlicher Sensor integriert oder eine Art Schalter angebracht werden, der bei Kontakt den Roboter startet.

> Output:
Zur Fortführung der Kette kann ich beispielsweise etwas anstoßen oder etwas überfahren (Drucksensor). Es ist auch möglich eine LED mit einer bestimmten Farbe leuchten zu lassen (habe rot, grün, blau, gelb, weiß sowie RGB Leds) oder etwas wegzuziehen (zum Beispiel ein Hölzchen, dass eine Kugel hält usw.)

[[:Category:Fachmodul|Fachmodul]] 
''Lehrperson:'' [[Frederic Gmeiner]] 
''Bewertung:'' 6 [[ECTS]], 4 [[SWS]] 
''Termin:'' Montag, 15:15 bis 18:30 Uhr 
''Ort:'' [[Marienstraße 7b]], Raum 104 (wird voraussichtlich noch geändert!) 
''Erster Termin:'' 17.10.2011

==Beschreibung==
Data Stories: Tools for self-reflection

Datenjounalismus bezeichnet allgemein die Verwendung von öffentlich zugänglichen Daten zur Generierung von (interaktiven) Informationsgrafiken zur Erweiterung klassischer journalistischer Reportagen. Die Form der »Datengeschichte« können jedoch auch für den persönlichen Gebrauch interessant sein, denn durch die stetig wachsende Präsenz von Sensoren in Consumer Geräten ist es heute sowohl für den privaten und individuellen Zweck ohne große Mühe machbar eigene Daten über sich selbst und seine Umwelt zu sammeln.

Wie lassen sich diese Daten, die bei der Benutzung von (digitalen) Geräten im Alltag entstehen, nutzen? Welchen Mehrwert können diese Archive für uns selbst oder für eine Gemeinschaft haben? Wie lassen sich gesammelte Informationen inszenieren, sodass diese einen persönlichen Wert erhalten?

Im Mittelpunkt des Kurses steht ein Selbstexperiment bei dem selbst gewählte Daten über einen Zeitraum gesammelt und anschließend inszeniert werden sollen. Hierbei soll eine Übersetzung eines analogen Datensatzes in einen digitalen (oder umgekehrt) stattfinden wobei die dafür verwendeten Geräte und Programme gemeinsam im Rahmen des Kurses entwickelt werden.

Auf der einen Seite werden technische Aspekte und Grundlagen des physical computings behandelt. Ausgangspunkt hierfür ist die Arduino Microcontroller-Plattform sowie die Programmierumgebungen Processing und OpenFrameworks. Je nach vorhandenem Kenntnisstand der Teilnehmer und Anforderungen des jeweiligen Projektes werden weitere Themen angeschlossen, wobei dieses auch in Form von Referaten geschehen kann.

Gleichzeitig sollen alle Teilnehmer im Kurs ein eigenes Projekt entwickeln bei dem das Entwerfen individueller Werkzeuge und Strategien zur Sammlung und Inszenierung (persönlicher) Daten im Vordergrund steht. Dieses kann sowohl anwendungsorientiert wie frei künstlerisch sein.

===English description===

How can we utilise all the meta-data that is being created by the usage of our everyday (digital) devices for an individual purpose? What is the benefit of these archives for ourself or a community? In what way can we stage information, so that it becomes more personal and emotional?

Together we will develop individual tools and strategies to collect and expose (personal) data, either with an application-oriented or an artistic approach.

In order to realise these projects, students will learn about the technical aspects and basics of physical computing with a focus on the Arduino micro-controller as well as the Processing and OpenFramework environments.

==Themen==
* Processing
* OpenFrameworks
* Object-oriented programming
* Arduino
* Overview and usage of libraries
* Reading and controlling of common sensors and actuators
* APIs and protocols like JSON / XML / OSC

==Voraussetzungen==
* Programmier- und Elektronikkenntnisse sind wünschenswert, jedoch nicht zwingend notwendig.
* Bitte wenn möglich einen eigenen Computer mitbringen.

==Anmeldung==

Julez: /* EHP - Emotion Heartbeat Project */

==EHP - Emotion Heartbeat Project==
 
The "Emotion Heartbeat Project" is a project that will collect my heartrate as a datatype. This data will be displayed in a visual way with diagrams and create an emotional diary out of that. With an increased heartrate the heartrate monitor will ask for the cause of it to differentiate between positive and negative stress or sports activities.
 
 

===First Ideas And Thoughts===

<gallery>

File:4_page4.jpg|Collected Heartbeat-Data Within 1 Week
File:5_page5.jpg|Heartrate Diagrams
</gallery>
 
One of my first ideas was to connect the heartrate monitor with headphones that would calm down my increased heartrate with music and vibrating sensors at my neck; showing picture 3 and 5. The decision diagram displays how this should work.
But within this semester I will just build up the heartrate monitor itself.

Picture 6 and 7 are showing the result of 1 week of collecting heartrate data. I counted my heartbeat within 1 minute manually 4 times a day for 1 week. Pic 6 shows a diagram displaying the whole week at a glance; Pic 7 shows the diagrams of each day in particular. (Unfortunately I couldn't get it work with a consistent scale for the heartrate.)

Inspired by diverse links and Youtube videos the very first try to build it was to use IR Emitter and Detector. It didn't work that well: the sensors are pretty sensitive for moving action and the signal at processing was very faint.

To amplify the signal I used a low voltage op-amp LM358N.
The images of the third gallery show the circuit, schematic and processing screen result.

The Data Logger Shield for the Arduino board is directly plugged on the top of it and will save the collected data to a SD card.

The selfmade sensor with the IR Emitter and Detector is very sensitive for any motion and movements of the finger being measured. So I tried out a EKG Sensor which displayed a higher resolution of the heartbeat on processing. There are 3 electrodes patches placed on the skin: One on the right wrist for the reference, one on right elbow for the negative alligator clip and one on the left elbow for the positive clip. The EKG Sensor is connected with the Arduino to Ground, 5V and Analog Input A0. The heartbeat is displayed with Processing.

This was a pretty good thing to test but unfortunately it wasn't convenient for a design to wear it every day and take everywhere I go. In cause of that and diverse failed trys to make a sensor by my own, I decided to buy a device. This device is a Data-Logger which goes with a chest strap: the chest strap measures the heartrate and the Data-Logger saves it every 2nd or each second. The saved values are collected in CSV-files which can be displayed with the program of the Data-Logger, shown with the images below.

The program of the Data-Logger to visualize the collected data is a pretty good way to have a quick view to the results of the measurements. But the CSV-files need to be cleaned of extreme and zero values which were saved in cause of disturbances between the connection of the chest strap and the Data-Logger. The following images below show possible interface designs to display the collected heart rate and to analyse the results.
