- 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?arrow_forwardComputer Digital Logic. Design 4 X 1 Multiplexer.

- A circuit has two pushbutton switches connected to pin PB2and PB3 and two LEDs connected to pin PC0 and PC1 of AVR ATmega16 microcontroller. Write a program to control the LEDs as when any pushbutton pressedthe two LEDs will blink at the same time with 800ms total delay time for every blink.arrow_forward1.

Given a 3-wire NPN inductive sensor, the black wire is to be connected to the and the brown wire to the to the 4. After connecting the load to an NPN sensor, the other terminal of the load will be connected to the 5. If a PLC, serving as load, uses a sinking input card, it needs a (PNP/NPN) proximity sensor. 6.
