To code an LED as output in Arduino, there are 3 places to edit your code:
- At the top of your sketch, define the pin you will use for the LED.
- In the void setup() function, add a pinMode statement to initialise the pin as OUTPUT.
- In the void loop() function, add statements to turn the LED on and off as required.
