- I have a wooden toy train that runs on wooden tracks. I would like to place two ESP-WROOM-32 Boards on top of the train. Broadcast communication (which involves radio frequency, not Wi-Fi) would help communicate about the train's lateness to five other wooden trains on the same track. Local communication would help communicate to the train station about the train's lateness. I would also need radio frequency Tx-Rx Modules for discharging and undergoing the signal, and repeaters just in case the signal loses power due to long-distance traveling. My wooden train should be automated. It should run at 4 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.
