I am trying to use Arduino Nano, RR-Cirkits BOD8 and CT coils to detect occupancy on a model train layout for the purpose of turning on LED signals. My system works perfectly sometimes but after working one or two times quits working entirely. At each occupancy event, a signal (LED) is shown on the BOD, sometimes the LEDs work, sometimes not. I have tried re-wiring, changing BOD units, adjusting sensitivity, etc. - nothing helps. I have double checked the wiring schematic and it is wired according to the sketch. It’s almost like something has to re-charge or ‘catch up’ in order for the system to work.
