Binary code is a way of representing information using only two values: 1 (on) and 0 (off). Computers and digital electronics use this system because it matches the simple on/off state of electronic switches. With just these two values, we can represent numbers, letters, and commands that control how machines work.
In this lesson, you’ll explore how binary code is used in electronics, especially how it helps us control things like lights using a component called the shift register.
Binary might seem simple, but it's the foundation of all digital systems. Let’s keep going and see how we can use binary to control LEDs.
