LED Blink

Solving Approach

How do you plan to solve it?

 set the pin to be output

in the loop:

set the output to be high

delay for 400ms

set the output to low

delay for 800ms
 

Code

/*Paste your code here*/

void setup() {
  pinMode(GPIO, OUTPUT);
}
void loop() {
  digitalWrite(GPIO, HIGH);
  delay(400);
  digitalWrite(GPIO, LOW);
  delay(800);
}
