That's very promising, those currents you measured are about right. ?Nothing's burning up. ?But I now have no idea why your audio started motorboating/skreeching at the same time as it got stuck in calibration mode. ?Very curious.
If you can compile and load a sketch to the Raduino, you could switch the calibration mode sense from A2 over to A0 as previously suggested. ?
Alternately, you could completely disable the check for calibration mode by replacing one line down at the top of the loop function (it's a zero, not the letter oohh):
old: ? ? ? if (digitalRead(CAL_BUTTON) == LOW && mode == MODE_NORMAL){
new: ? if (0){
If you don't want to go to a different calibration pin, you could just?
