Slipper Shining with LED strip & Xadow Using Arduino

LED strip Xadow (1)


Led strips are amazing! Firewalker-led-sneakers( by Adafruit inspired me.LED strip Xadow (1)

I wanna change a way to control it, instead of “pressure-sensitive”, I use a accelerometer sensor judging the motion of slipper.

It’s simple, I complete this version only calculating the acceleration on “z” axis, weather i’m speed up or slow down. Led will “flow” if I’m moving, and stop as I stop.

Step 1: Materials & Tools

shoe and model!
There is already a 3.7V lipo battery shipped with Xadow, due  to my experience this voltage can light up a short segment of RGB Led strip, if necessary you can calculate the max length it can support based on your specific one. For me, this is a W2818 programmable RGB Led strip with integrated driver.

If you wanna a more “blink” experience, please use an external 5V DC power or make a 5V booster  by yourself.

Step 2: Connect

How to:

Xadow main board <- I2C -> Xadow 3-axis <-> Strip

There is already breakout on accelerometer sensor, so you don’t have to add “Xadow breakout”.

Xadow use FFC between two modules, this 12Pin cable just fix the Xadow compatible interface.

For more info, please checkout wiki

Some solder works should be done: you have to connect pins to the breakout on Xadow.

Step 3: Blink Test

Since this is the same as NeoPixel Digital RGB LED by adafruit, if you wanna a quick implementation of beautiful animation with it, I highly recommend the code example  by Adafruit
