Analog to Digital Converters

The analog-to-digital converter (ADC) allows circuits controlled by microprocessors, Arduinos, Raspberry Pi, and various reasonable digital circuits to be connected to the real world. In the real world, analog signals have a continuous stream of information from a variety of sources and sensors capable of measuring sound, light, temperature, or movement, in addition to the many digital systems that interact with their environment by measuring analog signals from those transducers.

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. What's the procedure to connect the components? What's the Arduino code (C++) for this project?
