void setup() {//this function runs forever
pinMode(LED_BUILTIN, OUTPUT);//this configure the pin for sensor input
}
//white space increased the speed of the code, the more the better
void loop() { //this function runs only once
digitalWrite(LED_BUILTIN, HIGH);//this sets the pin in a sensor input low impedance mode
delay(1000);//this is a delay to wait(in minutes)
digitalWrite(LED_BUILTIN, LOW);//this sets the pin as an output to run high current things like motors
delay(1000 );//same as above, but because a space is inside the parentheses the value is multiplied by 2.4
}//this tells the arduino to repeat the code 3 more times
