Zuino M UNO Example Codes

Posted by Aswana, 08/11/2018

Note: This is the example code for our Zuino M UNO Qwiic Start blog.

This post is part of our Zio Qwiic Start Guide Blog Series.

Test Example Code: Blink

Step 1 Select Example code Blink

From your Arduino IDE, go to the ‘File’ tab, select ‘Examples -> 01.Basics -> Blink

 

You will be shown with the following code as shown below. Just leave it as is for now.

 

 

Step 2 Upload the example code to your board

Click the arrow button to upload your code to your board.

 

 

Step 3 Your Zuino board is now blinking!

 

 

Step 4 Test by making few changes to the code

 

Under the setup function you will see the following code:

 

// initialize digital pin LED_BUILTIN as an output.

 

pinMode(LED_BUILTIN, OUTPUT);

 

As explained in the comment section (marked with a forward slash ‘//’), this code pointed to the 13 digital pin, which by default is the pin connected to the LED as explained previously under the board overview. Just leave this code as it is for now as well.

 

To make changes to the code scroll down to the section under the loop section.

 

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

}

 

The code under loop function will repeatedly run your code unless you specifically told it to stop. To test your code for BLINK you can make changes to how FAST or how SLOW your LED Blink.

 

What does the code mean:

 

HIGH - simply means switching your LED on

LOW - simply means the opposite of HIGH, that is switching your LED off

delay - As the name suggests, this is the time taken for your code to ‘pause’. It is stated in milliseconds (ms) format. For example 1000 = 1 second.

 

To change how fast or slow your code blinks, you only need to change the time in delay section. Play around with the delay time and see how your Zuino board blinks :).

 

 

Aaaaaaaanddd it’s a wrap!

 

You now have a basic understanding of what your Zuino M UNO can do on its own. Play around with other Arduino IDE Example codes as well to further your understanding on our Zuino board.
