Reach out and touch someone, or something, with the MPR121 capacitive touch sensor and a Raspberry Pi or BeagleBone Black! This breakout provides 12 capacitive touch inputs and all the logic to read them over a simple I2C communication bus. For example you can make your own buttons, detect if someone touched a device, create a fun plush game controller, or even a wacky devices like a banana piano!
With the MPR121 python library you can now easily use the MPR121 capacitive touch sensor with a Raspberry Pi or BeagleBone Black. Follow this guide to learn how to connect the MPR121 to a development board, install the python library, and start using the MPR121 with your own programs on the Pi or BeagleBone Black. I’ll even show you how to create a ‘virtual keyboard’ to send key presses when inputs are touch on a Raspberry Pi–great for making a fun controller kind of like the Makey Makey!
