  • Click on the cog at the top right of CodeBug.

  • Under the Connected Hardware title, tick the CodeBug Colour Tail box.

  • Tick the check-circle for the Colour Tail you are using.

  • Click Apply button.

Setting a Colour Tail pixel

To control the LEDs on Colour Tail you need to use the blocks from the Colour Tail menu.

  • Click the Colour Tail menu.

  • Drag in a set colour pixel to colour block and snap it to the start block.

  • Set the colour by clicking on the coloured square and pick the colour you want from the window that appears.

Loop through the LEDs

To cycle a pattern on your Colour Tail, you need to change the colour of each LED in sequence.

  • From the Loops menu, drag in a count with block and snap it to your start block.

  • Drag your set colour pixel to colour block into your count with block.

  • From the Basics menu, drag in a pause block and snap it beneath your set colour pixel to colour block (making sure it is inside your count with block.

  • Drag the 0 block from inside your set colour pixel to colour block, into the bin.

  • From the Variables menu, drag in the i block, and snap it into the new gap in your set colour pixel to colour block.

  • Click on the second number block (after the text ‘to’) of your count with block and set it to one less than the number of LEDs on your Colour Tail.
