5.3 Demo Analog Input: Working with Potentiometer

In this section, we learn how to read analog input on Arduino Uno board. For illustration, I use Potentiometer as analog input source. Our scenario is to read analog value from Potentiometer. Then, display it on Serial Monitor.

Arduino Uno has Analog inputs on A0..A5. If you want to work with many analog inputs, you must expand it using ICs based ADC. In this section, we are working on Arduino Uno Analog inputs.

Let's start!.

5.3.1 Wiring

To understand Potentiometer, you see its scheme in Figure below.
