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?

Predictive maintenance is to be applied to an industrial conveying system.a) Discuss and illustrate the difference between reactive, preventative, and predictive maintenance.b)  Describe several of the techniques that could be used to develop a predictive maintenance system for the conveyor system. Consider some  of the  sensing techniques  that might be used and what parameters might be measured to detect component degradation.c)  If the predictive maintenance system described in b) detects that the conveyor system is vibrating abnormally, discuss what condition this could indicate and what maintenance might be required.
