- What are some applications of temperature-actuated switches?arrow_forwardI 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_forwardRequired information A fan is to run only when all of the following conditions are met: • Input A is OFF. • Input B is ON or input C is ON, or both B and Care ON. • Inputs D and E are both ON. . One or more of inputs F, G, or H are ON. Saved Note: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
