Uploading Code:
The following example demonstrates how to blink an LED connected to GPIO2:
// Define the GPIO pin for the LED
#define LED_PIN 2
void setup() {
// Set the LED pin as an output
pinMode(LED_PIN, OUTPUT);
}
void loop() {
// Turn the LED on
digitalWrite(LED_PIN, HIGH);
delay(1000); // Wait for 1 second
// Turn the LED off
digitalWrite(LED_PIN, LOW);
delay(1000); // Wait for 1 second
}
