Controlling an LED with Arduino is one of the simplest and most common beginner projects. It helps you understand digital output control and basic Arduino programming.
Steps to Blink the Built-in LED
1. Connect Arduino to PC
Use a USB cable to connect your Arduino Uno (or compatible board) to your computer.
2. Open Arduino IDE
Select the correct board and port from the Tools menu.
3. Write the Code
The built-in LED is usually connected to pin LED_BUILTIN (pin 13 on most boards).
// Blink built-in LED every secondvoid setup() {pinMode(LED_BUILTIN, OUTPUT); // Set LED pin as output}void loop() {digitalWrite(LED_BUILTIN, HIGH); // Turn LED ONdelay(1000); // Wait 1 seconddigitalWrite(LED_BUILTIN, LOW); // Turn LED OFFdelay(1000); // Wait 1 second}Copied!âś•Copy4. Upload and Test
Click Upload in Arduino IDE.
The onboard LED will blink ON and OFF every second.
