Example 1: Blink

Here's a quick example sketch to get the iconic blinking blue stat LED for Arduino blinking on the SparkFun Qwiic Micro; simply copy and paste from below, then click upload!

language:c
const int LED = 13; // Blue "stat" LED on pin 13

void setup() 
{
  pinMode(LED, OUTPUT); //set pin as output
  digitalWrite(LED, LOW); //turn LED off
}

void loop() 
{

  digitalWrite(LED, HIGH); // Blue LED on
  delay(250);
  digitalWrite(LED, LOW); // Blue LED off
  delay(250);
}

Now that you've passed the Arduino litmus test, you're all set up to start building your first project. If you haven't already, go check out our Qwiic eco-system which allows you to easily connect with sensors and other devices without the need for soldering.

In addition each add-on board within this eco-system has a library to get you started right away. For example, do you want to turn on a lamp with your SparkFun Qwiic Micro, better yet four lamps, or perhaps you'd like to see how much light your plants are getting?
