MPR121 turn (almost) any surface to a touch button for arduino
MPR121 is a 12 pin touch sensor, using capactince capabilites of the IC. Using a library from bare condustive, will be able to get trigered each time one of the pins is touched or released. And will build a 2 switch on/off buttons for a LED Link to bare conductive MPR121 library https://github.com/BareConductive/mpr121 My advantures with Bare conductive paint • My adventure with electric paint
