Daisy chain LED strips

Connecting the components
(a) Slot a BBC micro:bit to the breakout board
(b) Plug in a neopixel light strip to PIN1
(c) Using a pin connector, start chaining the rest of LED strips. Do ensure that the direction of Din flows!

Materials

• 1 x BBC micro:bit
• 1 x Tinkercademy breakout board
• Neopixel LED strips
• Pin connectors

Importing Extension
To connect a neopixel LED strip, we need to import a special package in MakeCode.

(a) Click on the ‘Advanced’ drawer, select 'Extensions'.

(b) Search for ‘neopixel’ and click on it to import.

(c) You’ll need to re-import the extension again for new projects in the future.

Initialise LED strip
Before coding for the LED strip, we need to initialise it.

(a) In the Neopixel drawer, drag a 'set strop to...' block into on start.

(b) Change the pin number.

(c) Change the number of pixels. In this tutorial, we have chained 30 pixels altogether.

Show rainbow
(a) Right after the LED strip initialisation block, drag a show rainbow block.

(b) To make the colors rotate, in a forever block, drag a 'strip rotate pixel' and a 'strip show' block.

Congratulations
You’ve successfully chained multiple LED strips together. Don’t forget to plug a micro USB cable from your laptop to the top of your micro:bit, and click ‘Download’ to download the code to your micro:bit.
