MPR121 Capacitive Touch Sensor on Raspberry Pi & BeagleBone Black

sensors_DSC00759

MPR121 Capacitive Touch Sensor on Raspberry Pi & BeagleBone Black is a new guide in the learning system:

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!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
