Chapter 3. Project 2 – Remote Controlled TV Backlight

In the previous chapter, Project 1 – LED Night Lamp, we dived into the amazing world of LEDs. We created some cool projects using different types of LEDs. Now, we will use another type of LED – an IR (Infrared) LED. In this chapter, we will start by learning the basics of IR LEDs and the basics of IR communication. Once you have learned about programming the IR sensor, we will use it to control a TV backlight using a remote. In this chapter, you will learn about the following:
