Blink Led
This is a basic operation, but you need to start small to figure out the more complicated.
This is an example of code in order to see the flashing green led on the Arduino board.
/* void setup() { // initialize the digital pin as an output. void loop() { |
In the “setup” it set the pin 13 of the board as an output
In the “loop” the led blink in cycles 1 second long [delay(1000)=1000ms=1s]
“digitalWrite” goes to write in the output an high or low signal of +5V or 0V.
