This breakout board is the simplest way to create a project with mutiple capacitive touch sensors. No microcontroller is required here - just power from 1.8 to 5.5VDC. When a person touches one of up to 5 conductive pads connected to the 5 left-hand pins, the corresponding LED on the right lights up and the output pin goes low. Note that only one contact will be detected at once. The board comes with a fully assembled board, and a stick of 0.1" header so you can plug it into a breadboard. For contacts, we suggest using copper foil, then solder a wire that connects from the foil pad to the breakout. The datasheet has many details on sensitivity and power usage.
