Bling Blink Bracelet
The flexible LED strip can transform into a colourful light bracelet when worn on the wrist. Bring it to your next dance party (or work meeting), and gesticulate wildly for some awesome flashing lights!
YOU WILL NEED
• BBC Micro:bit
• Basic:bit breakout board
• LED strip
• Flexible wristband (e.g felt or thick paper)
Cutting out a wrist strap
For the wrist strap, you can use any homemade strap, such as flexible cardboard, thick paper, or felt. You’ll just want to make sure you have a way to attach the strap around your wrist, and a way to secure the micro:bit, breakout board, and battery pack to the strap. Try rubber bands, or lots of tape.
Attaching the Breakout Board
Here, we’ve laser cut our felt so that it can go between our micro:bit and basic:bit. We align the felt holes to match the five screw holes on the breakout board. Depending on the breakout board you’re using, how you attach it will vary-again, tape or rubber bands can work just fine!
Screwing on the micro:bit
Next, we use screws to attach the micro:bit to the basic:bit breakout board, securing the felt wrist strap in between.
Attaching the battery pack
Finally, we plug in the battery pack, and attach it to the wrist strap. Our design has a handy pouch for easy battery pack storage!
Try it out!
Shake it all about!
