Topic: MPR121 simulated 13th pin (Read 940 times) previous topic - next topic


hi guys

just started rocking out with my mpr121... it's great!

however, the twelve pins are not enaugh.i am making a one octave keyboard (c - c') so i need 13 touch sensors.

i wanted to know if you guys could give me some tips on how to make a "simulated 13th pin"? stuff to read etc...

any help would be greatly appreciated!
thank you



You can use the analog pins as digital ones - that gives you another six to play with.


im talking about the pins on the MPR, not the arduino...
