I am using a MPR121 capacitive breakout module by sparkfun.
I have the wiring OK and it works fine when only the module is plugged to the arduino.
The problem started when i plugged leds and waterpumps in the arduino digital pins to respond to the capacitive sensor inputs. when other things are conected the arduino does not find the MPR121.
i thought something was wrong with the mpr121 and i unplugged everything that wasn't related to the module and it worked again
why does this happen and how do i fix it?
I didn't find the right solution from the Internet.
