Introduction: 3D Printed LED Bracelet With Motion Sensor
This project started when I printed Diagrid Bracelet by nervoussystem and got the idea to add some LEDs to it. I designed the model using123D Design. An Adafruit trinket (Attiny85) is controlling a Neopixel 144 LED/m strip and reading value from a FLORA Accelerometer/Compass Sensor (LSM303) using I2C.

I printed it on a Form 1 using white resin.
Print the model and glue the magnet.
Step 3: Electronics
- Trinket - 3.3V Logic
- 144 LED/M Neopixel strip
- Smal battery (~110 mAh)
- Neodymium magnets (3 mm)
- FLORA Accelerometer/Compass Sensor - LSM303
Connect the led stripe to D1 to one of the trinkets pins, I use pin 1, and connect +5v to the battery positiv and GRD to negativ. To connect the accelerometer use pin 0 for SDA and pin 2 for SCL.
Step 4: Code
Step 5: Party!
