			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.

	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.

	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.)

	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.
