Capacitive Touch Sensing with the MPR121
If you want to work with capacitive touch sensing in AIR LAB, we have several MPR121 modules available for Arduino. This is a tutorial of how to get started with the very basics of capacitive touch sensing. This includes how to establish electrodes as toggles, buttons, and proximity sensors via the MPR121 library, published by Bare Conductive. At the very bottom of this page, we have gathered useful documentation to help you get further with capacitive touch sensing if needed. What is capacitive touch sensing? Capacitive touch sensing, is at its very core a constant measure of the change in the conductivity of a circuit.…
