Chapter 2. Control Lights from Your Phone or Tablet
In this chapter, we are going to tackle another very common project in any home automation project: controlling lights. There are many devices that you can buy off the shelves that will give you the ability to control devices in your home, but these devices usually have a high price point. And even if they are wireless, they usually come with a remote control.
In this project, we are going to take another approach and control lights directly from your computer, phone, or tablet, all via Wi-Fi. The following will be the major takeaways from this chapter:
- First, we are going to build the hardware part of our project by connecting a Wi-Fi chip to Arduino and the device we want to control (here, a simple lamp) to a relay module. We'll actually use two relay modules in this project, but this can, of course, be extended to any number you want.
- Then, we are going to write some basic code to test the different parts of the project...
