I have an O Gauge track and would like to convert it into a “sensored” track. Additionally, I would like to connect that track to an ESP-WROOM-32 board that should flash an LED whenever the track detects a non-moving train. Please list all the components (and how many of each) needed. Also, what’s the procedure for connecting the components?
