-Capacitive touch sensing with MPR121
----------------------------
-
-This sketch allows you to hook up an MPR121 capactive touch sensing device
-to Bela, for example the SparkFun Capacitive Touch Sensor Breakout - MPR121.
-The breakout board gives you 12 electrode connections.
-
-To get this working with Bela you need to connect the breakout board to the I2C
-terminal on the Bela board. See the Pin guide for details of which pin is which.
-
-The sensor data will then be available for you to use in the array
-`sensorValue[NUM_TOUCH_PINS]`.
