Introduction: Color Changing/Sound Activated LED Jacket
Using a Circuit Playground Express and some LEDs you can upcycle a jacket from the back of your closet to the front of stage!
By the end of this instructable you will have created a stylish LED jacket featuring:
- 7 Color modes
- 4 Pattern modes
- Sound Activation
Supplies
1x USB Powerpack/ Battery Pack
Addressable LEDs – These prewired ones made it a lot easier!
Wires!
Needle and Thread
Old Jacket
Step 1: Diagram & Prepare Wiring
Measure wire lengths from Led sleeves to power source. For ease, I ran full length from both arms to a front pocket that will be used to house the Circuit Playground Express(CPX) and battery module.
Both strips will connect to the same data/power/ground so feel free to splice the respective wires together anywhere along the path. I just waited until the end.
(Optional) – Add connectors to ends of wiring/led strips if you want to make it modular.
Step 2: Prepare Jacket – Cut Tiny Slits in Line With Where the Leds Will Be.
Since the the leds are pre-wired, I laid them out on top of the sleeves and cut them as I went. Weaving them= strip through the holes I learned the smaller you can make the slits the better the leds will hold in place before sewing.
Step 3: Sewing Leds in Place
Hand sew each led so it doesn’t twist or pull though the slits as you wear and stretch the jacket. In the future I will probably sew in more of the wiring as
Step 4: Circuit Playground Express - Wiring and Programming
Wiring the CPX is simple...
LEDS
-Data wires from both arm strips connect to A1
-Ground wires to ground
-Power wires to Vout
Programming was not as simple but not too hard with the drag and drop coding UI!
- A and B buttons scroll through color/pattern options
- A+B changes color/pattern mode
- Switch toggles sound activation

*Sound activation sensitivity can be changed in the Sound Activation forever rule.
