yesterday I got my first Arduino. Here it is my first sketch… the blink sketch 🙂

And the Arduino IDE blink sketch

// the setup function runs once when you press reset or power the board
void setup() {
 // initialize digital pin 13 as an output.
 pinMode(13, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
 digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level)
 delay(150); // wait
 digitalWrite(13, LOW); // turn the LED off by making the voltage LOW
 delay(150); // wait
}
