Capacitive Touch Shield

by toppac on Thu Sep 12, 2019 2:38 pm

Newbie question. I just got the 12x Capacitive Touch Shield and stacked it on my Uno but I'm getting no connection with it. I haven't soldered the pins yet so maybe that's the issue but I assumed it would still work without. I've run the sample sketch as well as the i2c scanner sketch. Both either hang or report "MPR121 not found, check wiring?"

Posting pics below. Just need some newbie advice to get this started so I can learn with it.
