#67613 ...and to what port/pin is the LED connected? :?:

You're using an Arduino sketch, which (in theory) is fine, but most of the time you need to edit some stuff like used port numbers for used LEDs and switches. :idea:


Also please use [ CODE ] tags on this forum to show the sketch like this:
Code: Select all/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the Uno and
  Leonardo, it is attached to digital pin 13. If you're unsure what
  pin the on-board LED is connected to on your Arduino model, check
  the documentation at http://www.arduino.cc

  This example code is in the public domain.

// the setup function runs once when you press reset or power the board
void setup() {
  Serial.begin(115200);
  Serial.println("Blink Test LED");
  // initialize digital pin 7 as an output.
  pinMode(7, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(7, HIGH);   // turn the LED on (HIGH is the voltage level)
  Serial.println("LED High");
  delay(1000);              // wait for a second
  digitalWrite(7, LOW);    // turn the LED off by making the voltage LOW
  Serial.println("LED Low");
  delay(1000);              // wait for a second
}
