Arduino Capacitive Touch Shield, MPR121, 9 Pads, 3 Extra Inputs US$14.95

DEV-12013
Arduino Capacitive Touch Shield, MPR121, 9 Pads, 3 Extra Inputs


The Touch Shield has an MPR121QR2 IC to build simple capacitive touch interfaces for your Arduino projects. The shield has nine capacitive touch pads, with headers for the remaining three electrode connections, giving you a potential total of 12 touch-sensitive buttons.

An on-board logic-level converter allows it to work with 5V and 3.3V Arduino boards. Simply solder on some header pins and stack it on to your Arduino for a convenient input device. Check below for some example code to get you started.

Keep in mind that this shield provides nine touchpads not 10 so it isn't suitable out of the box for number-entry applications that require a zero. It has through-hole pads for connecting three external inputs; you could assign one of those as a zero.
