Adafruit 12 x Capacitive Touch Shield for Arduino - MPR121

This touch-able add on shield for Arduinos will inspire your next interactive project with 12 capacitive touch sensors. Capacitive touch sensing works by detecting when a person (or animal) has touched one of the sensor electrodes. Capacitive touch sensing used for stuff like touch-reactive tablets and phones, as well as control panels for appliances, which is where you may have used it before. This shield allows you to create electronics that can react to human touch, with up to 12 individual sensors.
