Examples for Sensors and usage
Reusing Hardware - Keypad: http://hackaday.com/2012/04/11/adding-an-electronic-lock-to-a-diy-book-safe/
Magnetism
Reed Switch: (a Magnet Sensing Switch) http://www.youtube.com/watch?v=sl8ItZxGM6E
Hall Effect Sensors (Magnetic Sensors - non mechanical, opposed to the reed switch) http://www.youtube.com/watch?v=9BFdGtvo9JE (too long to watch for class, but good explanation)
- switching
- analog field strength.
Electronic compass. / Magnetometer
Position and Movement
Theremin Sensor: http://interface.khm.de/index.php/lab/experiments/theremin-as-a-capacitive-sensing-device/
Distance Sensor (Ultrasonic): http://hackaday.com/2012/04/04/make-your-rc-car-drive-itself-with-this-simple-brain-swap/ http://www.arduino.cc/en/Tutorial/UltrasoundSensor
Sharp IR Distance Sensor: http://luckylarry.co.uk/arduino-projects/arduino-using-a-sharp-ir-sensor-for-distance-calculation/
Audio
Audio Input as Control - Hack Cellphone + Attach Arduino instead Keypad http://hackaday.com/2012/04/03/recorder-controlled-snake-game-played-on-a-nokia-6110/
Wave Shield: http://www.ladyada.net/make/waveshield/
Wave Shield Demo: (SD-Card + Shield) http://www.youtube.com/watch?feature=player_detailpage&v=0mdmasP_Z-Q#t=28s
comes as a Kit (good entry level soldering exercise): http://www.ladyada.net/make/waveshield/parts.html
Mechanical Input:
- Buttons / Switches

Wireless Drills http://hackaday.com/2012/03/30/loudest-telepresence-robot-ever/ more professional - Big Bang Theory: http://www.youtube.com/watch?v=sbypsMauqOY&feature=player_embedded
Solenoids Stepper Motors DC Motors
Capacitive Sensing
Main Application Today: Touch Screens http://hackaday.com/2012/03/27/piano-box-is-a-digital-synthesizer-made-of-paper/ http://www.instructables.com/id/DIY-3D-Controller/ Capacitive Water Level Sensing: http://www.youtube.com/watch?v=_GPvCxkWgbE
Displays:
LED 7-Segment-Display: http://tronixstuff.wordpress.com/
LCD Shield: http://www.dfrobot.com/index.php?route=product/product&product_id=51 http://www.youtube.com/watch?feature=player_detailpage&v=JDoTn1sLxWQ#t=57s (+ Guide for general LCD Displays)
- search for the display model in case you don't know whether it is easily controllable using arduino.
LED-Matrix (2D) and Lens = Projector. http://tinkerlog.com/2008/08/31/led-matrix-projector/
Arduino 5x7 LED Matrix Display http://www.youtube.com/watch?v=Z6Wv3CiSTfo

Other Connections:
Arduino + Android: (Advanced Level!) http://mitchtech.net/android-arduino-usb-host-temperature-light/
Ethernet Shield: http://arduino.cc/en/Main/ArduinoEthernetShield
- Twitter, Facebook, your own website on The Arduino Webserver, ...
- SD Card for increased storage (Arduino has ownly a few kilibytes, this extends it to 2GB)
Brightness: Photo Diode, Photo Transistor
- fast
- measure current
- photo-transistor: 2 or 3 pins - usually only 2 of them needed.
- photo diode: 2 pin device. Many types visually not to distinguish from LEDs
- polarity does matter.
LDR: Light Dependant Resistor
- slower
- no polarity (usage more simple).
Temperature:
- NTC, PTC: Resistors which change their resistance.
- Many different temperature sensors available (digital interface, analog output voltage)
differ in temperature range, interface, size, ...
Sound:
Microphones
- dynamic, electret or condensor microphones - used for sound in air (flute example)
- piezo (body sound, under water microphones) http://www.youtube.com/watch?feature=player_detailpage&v=NgvG2WWTD8A#t=20s
Knock Tracking: http://www.emeraldinsight.com/journals.htm?articleid=1464099&show=html
Movement
PIR Passive Infrared: Detects changes in temperature (thermal radioation) - widely used to switch lamps on by movement. - in commercial products: often have a brightness sensor included to only work in dark environments)
