Getting Started with Igloo: 'Hello World'

This is a tutorial for Igloo, the Sewable PICAXE wearable module from Kitronik.


Tutorial 1: 'Hello World'

Learning Outcomes:

  • Learn how to flash an LED on the Electro-Fashion: Igloo PICAXE Wearable Module.

Level of Difficulty:

  • Beginner - Learn how to get started with the Igloo PICAXE Wearable Module.

For this tutorial, you will need:


You will also need the following equipment:

  • A laptop or computer with the Blockly program installed on it.


Step-by-step guide to making an LED flash:

Step 1:



Connect the Igloo Board to the power supply and insert the programming cable.

Step 2:


Start by opening up a new project in Blockly. Then from 'Loops' select a 'Forever Do' block. Connect that to your start block.


Step 3:



From 'Outputs', choose an 'Output on' block. Connect that to your 'Forever do' loop.

Then, from 'Delays', choose pause for 500 milliseconds and connect that to the bottom of the turn 'Output On' block.

Step 4:


We're going to be using 'B2'; the on-board LED, so change 'B0' to 'B2'. Because we want to make this flash, lets duplicate the 'Turn Output On' block.

Step 5:


Duplicate the 'Pause for' block. Connect those together and we'll change 'on' on the 'turn output B2' block to 'off'. We'll then connect that into the loop.


We now have a program that turns 'B2' on and waits for 500 milliseconds, and turns 'B2' off for 500 milliseconds, and loops back to the beginning. This will make the LED flash.

Step 6:


When you have completed your program, click on PICAXE and click on 'Program'. This will upload the program to the Igloo microcontroller.


Now our program has been uploaded to Igloo. We can see the on-board LED B2 flashing on and off. A simple program like this is called 'Hello World'.
