Flora Brake Light Backpack #WearableWednesday

Say hello to my new favorite bag! Improve your visibility on your motorcycle by installing an LED pixel display inside your backpack! This weather-resistant project uses a Flora and accelerometer to auto-detect braking and uses a simple wireless module to trigger turn signal animations. Check out the complete tutorial on the Adafruit Learning System, download the code from Github, and watch the video on YouTube (please subscribe) or Vimeo.

Flora breadboard is Every Wednesday is Wearable Wednesday here at Adafruit! We’re bringing you the blinkiest, most fashionable, innovative, and useful wearables from around the web and in our own original projects featuring our wearable Arduino-compatible platform, FLORA. Be sure to post up your wearables projects in the forums or send us a link and you might be featured here on Wearable Wednesday!


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. Very nice build- we’ve been talking about something similar for scooter and bike riders here on Maui. These folks are hard to see normally, and given how many ride in the rain, with even less visibility, the packs would be great.

    Couple things I was thinking about with the design/project…
    1) Flora is about as easy to get as a Raspberry Pi these days – which for most of us means not at all. Backorders may come in but the wait list seems longer than the shipped supplies.
    Since you are not sewing any connections to the Flora, any arduino compatible would do. Teensy or Arduino Micro should be sufficient (although the 3.3v accelerometer would need level shifter).

    2) How about adding some waterproof connectors and Cable Glands
    https://www.adafruit.com/products/744 4 wire for LEDs
    https://www.adafruit.com/products/743 2 wire for switch
    https://www.adafruit.com/products/761 for gland
    The connectors would make it easier to remove the control box for reworking separate from the backpack.
    The gland would be an alternative to the Sugu, but that miracle material might be a better choice in this case.

    Thanks for the article!
