Tinkercad Tutorial for Beginners–Part 6 | Adjust LED Brightness with a Potentiometer | 3Gen Techies

In this beginner-friendly Tinkercad tutorial, we will learn how to adjust LED brightness using a potentiometer with Arduino Uno. This project helps you understand analog inputs and PWM (Pulse Width Modulation) for smooth LED dimming.

Project Overview:

A potentiometer acts as a variable resistor that changes voltage levels. The Arduino reads this value and adjusts the LED brightness accordingly using PWM. This concept is widely used in light dimmers, volume controls, and other analog adjustments.

Arduino Code:

int potPin = A0;
int ledPin = 11;
void setup() {
pinMode(ledPin, OUTPUT);
Serial.begin(9600);
}
void loop() {
int potValue = analogRead(potPin);
int brightness = map(potValue, 0, 1023, 0, 255);
analogWrite(ledPin, brightness);
Serial.print("Brightness: ");
Serial.println(brightness);
delay(10);
}
