Summary
We will be ending this chapter with that. There is a lot more to do, which will be discussed in part 2—the next chapter. What have we learned in this chapter? We have learned a lot about relays, from how they work to how to work with them. We also took considerable time to fully gauge how the relay functions in conjunction with a simple and two-way switch. We also understood why a two-way switch is better for control. We also programmed the Arduino to control a light's switch and built a circuit to achieve the same, with the help of an electrician (or not). Finally, we took it one step higher by adding a communication layer (via terminal).
The next thing on the to-do list is to create a communication layer that allows communication through ...
