I have a wooden toy train that runs on wooden tracks. I would like to place an ESP-WROOM-32 Board on top of the train. I would like to use broadcast communication (which is radio frequency, not Wi-Fi) for this project. Broadcast communication would help communicate about the train's lateness to five other wooden trains on the same track. My wooden train should be automated. It should run at 3 inches per second, keep a minimum distance of 30 seconds away from the other wooden trains, and make a 17-second-long stop every 500 seconds.
