Dear Bela community!
For a university project I've conceived a touch controller for modular synthesizers using an Arduino nano and three Trill Sensors (2x Square, 1x Ring). On the ring sensor I'm trying to use the connectors for two extra capacative buttons but I can't get them to work, no matter what i do.
I've tried adjusting the Ring example to always go into the "button loop" but nothing is ever printed to the serial console, even without the "getNumButtons" condition. How can I get the outputs work?
Another problem that occured in the process is that the solder bad for button B broke off after I soldered a wire to it (the wire broke off with the pad on it's tip). Now all there is left is a tiny little cable, which I cant connect anything to anymore. I attached a picture of the backside of the sensor. Any tips for this? Did I do somthing wrong?
Any help is greatly appreciated!
