Circuit Playground Bike Glove Light and Custom FLORA PCB with Compass

Thanks Lim for participating in last week’s Show-and-Tell and also for sending in these higher resolution stills and video showing off his projects!

Here’s a video showing the shake-n-glow activation of the bike glove – one shake to turn it on, another to switch off the LEDs:

Very cool!

UPDATED with text from Lim with a bit more about how the projects operate:

This is my custom FLORA board that uses a M0+ and a compass sensor.

There are a few desoldered components, which were removed in my quest to find what was causing the readings on the LSM303 to read only a small range of values. It turns out that I placed my metal reset button too close to the compass sensor, thereby affecting the readings. Once I removed it the charlieplexed LEDs on the edges of the board were able to point me North no matter how I rotated the board.

This was meant to be a drop-in replacement for the Adafruit circuit playground as seen in the video. The user (me) which direction they are going. The light up glove (I call it the Wayfinder Glove) has some debounce code so that the lights don’t flicker when I’m going over rough patches in the road. The LEDs are sewn on the knuckles so that they light up the way ahead. The LEDs on the glove can be used to flash a turning-left or turning-right sign when they are oriented in a specific position. Eventually I hope to integrate it with a bluetooth module so that my phone can stream GPS data to my glove and it will point me to the next waypoint.​​

And here’s a close-up of Lim’s custom FLORA-based PCB with compass in lieu of the WS2812 LED:

Featured Adafruit Products!


Circuit Playground – Developer Edition: Circuit Playground features an ATmega32u4 processor, just like our popular Flora. The board’s also round and has alligator-clip pads around it so you don’t have to solder or sew to make it work. You can power it from USB, a AAA battery pack, or with a Lipoly battery (for advanced users). Just program your code into the board then take it on the go! Read more.


FLORA – Wearable electronic platform: Arduino-compatible – v3: FLORA is Adafruit’s fully-featured wearable electronics platform. It’s a round, sewable, Arduino-compatible microcontroller designed to empower amazing wearables projects.FLORA comes with Adafruit’s support, tutorials and projects. Check out dozens of FLORA tutorials on the Adafruit Learning System, with more added all the time! Read more.
