Hello World Arduino Uno R3 Morse Code Sketch – 2016

keving — Fri, 11 Nov 2016 20:09:39 +0000

Recently I decided to get started prototyping the VR device I invented back in 2014. I chose to use an Arduino Uno R3 for my micro-controller. I was amazed how easy it was to get started right out of the box!

Below is a copy of my first Arduino “Sketch” (they are known as sketches rather than programs or scripts), it repeats “hello world” in Morse code.

This is a very simple way to accomplish this, not necessarily the best way. I don’t store any values or functions which would probably improve the efficiency a little.



void setup() {

  pinMode(13, OUTPUT);
}
void loop() {

  //hello world morse code
  //H

  digitalWrite(13, HIGH);   // sets the LED on

  delay(200);                  // waits for a second

  digitalWrite(13, LOW);    // sets the LED off

  delay(100);

  digitalWrite(13, HIGH);   // sets the LED on

  delay(200);                  // waits for a second

  digitalWrite(13, LOW);    // sets the LED off

  delay(100);

  digitalWrite(13, HIGH);   // sets the LED on
