Connecting Components:
Using Shields and Modules:
The following example demonstrates how to blink an LED connected to pin 13:
// Blink an LED connected to digital pin 13
// This code toggles the LED on and off every second.
void setup() {
pinMode(13, OUTPUT); // Set pin 13 as an output
}
void loop() {
digitalWrite(13, HIGH); // Turn the LED on
delay(1000); // Wait for 1 second
digitalWrite(13, LOW); // Turn the LED off
delay(1000); // Wait for 1 second
}
