This is a library for the MPR121 12-Channel Capacitive Sensor
|
|
|
|
Designed specifically to work with the MPR121 breakout from Adafruit
|
|
----> https://www.adafruit.com/products/1982
|
|
|
|
These sensors use I2C to communicate, 2+ pins are required to
|
|
interface
|
|
Adafruit invests time and resources providing this open source code,
|
|
please support Adafruit and open-source hardware by purchasing
|
|
products from Adafruit!
