5BLINKING A LIGHT FOR THE FIRST TIME
When I was a kid, one of my very first electronics projects was making a light blink. It was amazing to see the circuit work for the first time, and now I want to share that experience with you. In this chapter, you’ll learn how the capacitor and the relay work. These are two common and very interesting electronics components, and I’ll show you how to have some fun with them. At the end, you’ll build your very own blinking light!
MEET THE CAPACITOR
The capacitor is like a rechargeable battery; you can charge a capacitor and use its energy to power something. But a battery can hold much more energy than a capacitor. ...
