Analog and Digital Signals | What are the difference between analog and digital?

What are Analog signals and Digital signals? Understanding the difference between analog and digital signals is essential when learning about electronics, robotics, or even audio and communication systems. In this video, we break down what analog and digital signals are in the simplest way possible.

You'll learn how analog signals continuously vary over time — like the smooth volume changes from a knob — and how digital signals jump between fixed levels, like ON and OFF states.

We also compare both types of signals using real-world examples and visual demonstrations. From the output of a microphone to the signal from a push-button or a microcontroller pin, you'll see how each type of signal behaves.

We also show how Arduino reads analog signals using an ADC and converts them into digital values. So, get ready to learn with easy examples, clean visuals, and beginner-friendly language!
