Arduino LED Blink tutorial

Quick introduction to R3aktor and the Arduino IDE by blinking the onboard LED

Introduction

This tutorial is a brief introduction to the Arduino IDE and is intended to show just how quick it can be to program and deploy software onto your R3aktor development board.

Load the Blink Example

Begin by opening the Arduino IDE and then select File -> Examples -> 01.Basics -> Blink. A new window will open.

This will load one of the example sketches (what the Arduino IDE uses to refer to programs), which will look something like this:

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}
 
// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}

This program (sketch) begins by configuring the digital pin which controls the R3aktor LED as an output. LED_BUILTIN is a special symbol that is used to refer to the built-in R3aktor LED that's located next to the USB-C port.

Connect your R3aktor M0 Logger to your computer via USB-C cable.
