In this case I used the MAKE controller - connected the output wire from Step 2 (which was an LED there) into the 4th Input pin of the controller boar...
This is a short instructable on how to use the Qprox IC (QT113G) as a touch sensor. Using this IC, you can essentially turn any object into a touch switch. This simple circuit may be hooked up to a microcontroller (in this case I used the MAKE controller board).
Step 1: Gather all the necessary parts
1. QT113 - can be ordered at Digikey DigikeyDigikey. Each one costs around $2. 2. 10mF capacitor 3. Wires 4. LED 5. breadboard or perfboard (if you choose to perf, you will obviously need a soldering iron and some solder)
