int led = 13;//pin 13 as OUTPUT LED pin
int resetPin = 12;
// the setup routine runs once when you press reset:
void setup() {
digitalWrite(resetPin, HIGH);
delay(200);
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
pinMode(resetPin, OUTPUT);
Serial.begin(9600);//initialize Serial Port
Serial.println("reset");//print reset to know the program has been reset and
//the setup function happened
delay(200);
}
// the loop routine runs over and over again forever:
void loop() {
delay(10);
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
Serial.println("on");
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
Serial.println("off");
delay(1000); // wait for a second
Serial.println("resetting");
delay(10);
digitalWrite(resetPin, LOW);
Serial.println("this never happens");
//this never happens because Arduino resets
