void setup() {
pinMode(pin, OUTPUT); // sets the digital pin as output
}
void loop() {
digitalWrite(pin, HIGH); // sets the digital pin on
delay(1000); // waits for a second
digitalWrite(pin, LOW); // sets the digital pin off
delay(1000); // waits for a second
}
Notes and Warnings
• The pins 0~13 are all digital pins.
• Do not use pins 0 and 1, as they are used to communicate with the computer. Connecting anything to these pins
