The Best DIY STEM Tutorials and Projects
OVERVIEW
In this project, we’ll learn how to take input from a potentiometer and read its values using Arduino! A potentiometer works like a volume knob, changing resistance as we turn it. We’ll see how Arduino captures this data and displays it, helping us understand how analog inputs work. Get ready to twist, turn, and explore! 🔄✨
You can follow this video and the instructions below.

Program / Code
Code is Explained in the Comments of the Code
const int potPin = A0; Potentiometer connected to analog pin A0
const int ledPin = 6; LED connected to digital pin 7
void setup() {
Serial.begin(9600); Initialize serial communication at 9600 baud
pinMode(ledPin, OUTPUT); Set LED pin as output
}
void loop() {
int potValue = analogRead(potPin); Read potentiometer value (0-1023)
Serial.println(potValue); Print potentiometer value to Serial Monitor
analogWrite(ledPin, potValue 4); Set LED brightness (divide by 4 to fit PWM range)
delay(100); Small delay to prevent flooding the Serial Monitor
}
