The Arduino Uno R3 is one of the most popular microcontroller boards for beginners. In this tutorial, we will build the classic Arduino LED blink project, which helps you understand the basics of Arduino programming.Components RequiredArduino Uno R3LED220Ω resistorBreadboardJumper wiresArduino
int ledPin = 13;
void setup() {
pinMode(ledPin, OUTPUT);
}
void loop() {
digitalWrite(ledPin, HIGH);
delay(1000);
digitalWrite(ledPin, LOW);
delay(1000);
}
ConclusionThis project is the first step toward learning Arduino programming and embedded systems.
