CRAFT Video: LilyPad Arduino Blinking Bike Patch

Craft & Design



In this intermediate soft circuit tutorial, I show you how to make a light-up patch that can be used on your backpack for fun and bike safety. If you missed my LilyPad Arduino 101, you may want to watch that first. The theme of this year’s Maker Faire is “Re-Make America” so I thought I’d add some red, white, and blue LEDs to my messenger bag. I added them to a removable patch (from the fatlab, an artist collective I’m part of) so I can easily remove it at the airport, in the rain, etc. I used a rechargeable lithium polymer batter to power the whole thing because it’s flatter, lasts longer, and can be recharged instead of thrown away. I also made an Instructable where you can find links to all the supplies I used. You can download the source code and schematic for this project to get started on your own!

    I honestly could not read this as “fatlab” and was trying to parse it as Arabic.. :)

    To end your special case, change your order of operations.
    Turn on lights, sleep, turn off lights, loop.
    This will keep you working with the same numbers without a wraparound problem.

    Becky – Not only is this a completely awesome project, but you also reminded me of a great 8bitpeoples album I had entirely forgotten. Thanks!!!
