Hi again,I left more questions and pics on my pin-pointer pcouinterA problem at this link:https://www.instructables.com/topics/Pin-pointer-m...hope you can give me some help with the front end.Jon T

Hi,I bread-boarded your circuit for just the end coils to start, and loaded the sketch. It seems to be pulsing the coil OK but the leds aren't responding nor the buzzer.I uncommented the serial port code and it shows ledthreshold1 always at .97, pcounterA at 12, and calav1 at 81. Is this OK? (The other reported variables are always 1000.)I wound the end coils with some bifilar wire I reclaimed from a microwave HV supply transformer. I assumed that was OK?Do you have a flow chart or description of how the code works so I can trobleshoot?Any help or hints would be greatly appreciated.Jon T
