It is often desirable in designing an electric wiring system to be able to control a single appliance from two or more locations, for example, to control a lighting fixture from both the top and bottom of a stairwell. In home wiring systems, this type of control is implemented with three-way and four-way switches. A three-way switch is a three-terminal, two-position switch, and a four-way switch is a fourterminal,two-position switch. The switches are shown schematically in P2.40(a), which illustrates a three-way switch, and 2.40(b), which illustrates a four-way switch. If the lamp (appliance) is to be controlled from more than twolocations, four-way switches are used in conjunction with twothree-way switches. One four-way switch is required for eachlocation in excess of two. Show how one four-way switch plus twothree-way switches can be connected between a and b in P2.40(c) to control the lamp from three locations. (Hint: The fourwayswitch is placed between the three-way switches.)
Question 13
What is the total number of systems?
Is there anything unique about CPLDs?
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?
