Welcome to Learn4u !
In this tutorial, I'll show you how to create a project "Arduino RGB LED Control Tutorial!"this project is perfect for creating colorful light displays and learning about pulse-width modulation (PWM) with Arduino.
🛠️ Materials Needed:
- Arduino UNO
- RGB LED
- Three 220-ohm resistors
- Breadboard and jumper wires
- USB cable for Arduino
- Computer with the Arduino IDE installed
Setup Guide
1. Place the RGB LED on the breadboard, ensuring the longest leg (common cathode) is connected to the GND on the Arduino using a jumper wire.
2. Attach a 220-ohm resistor to each of the other three legs of the RGB LED.
3. Connect the free ends of the resistors to digital pins 9, 10, and 11 on the Arduino for red, green, and blue, respectively.
💻 Writing the Code:
Open your Arduino IDE and create a new sketch. We'll write a simple program of Arduino RGB LED Control !. Check out the code snippet below:

🚀 Uploading the Code and Testing:
Connect your Arduino to your computer via USB, select the correct board and port, and hit the upload button. Watch as your LED smoothly fades in and out. If it's not working, double-check your wiring and code.
