My solution to mini project 1 Day 4

LBD3-MP1.ino

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

// the loop function runs over and over again forever
void loop() {
  make_it_blink();
}


void make_it_blink() {
  digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}
