This project is a capacitive touch sensing keypad with 6 buttons based on the QProx QT160 charge transfer proximity sensor chip. When a button is pressed the circuit provides some visual feedback, a clicking noise and translate the output into an i2c bus signal. Special mylar capacitors are required for it to work properly. Check details on the link below.
