A supermarket has a one entrance-door and one exit-door. The customer capacity of the supermarket is 500. Entering and leaving customers are detected by door sensors. In the morning all doors are opened by pressing a start-system button. When the number of customers inside equal or greater than 500 entrance is closed. Entrance is opened again when the number of customers inside drops to less than 400. In the evening a stop- system button is pressed and all doors are closed. Write a FBD program for this problem.

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?
