An arduino wearable fashion tech project

Materials:

• Adafruit Trinket Mini 5V
• Neopixel Jewel
• LiPo 105mAh Battery

Wiring Diagram:

Build Process:

1. I checked the Adafruit Trinket first by uploading the convenient Blink! test code to the Trinket using the Arduino IDE.

2. I soldered the data, ground, and power wires to the Neopixel Jewel.

3. I uploaded the trinket_ring.ino code to the Trinket. I attached the wires from the Neopixel Jewel to the Adafruit Trinket using alligator clips.

4. In order to power the Adafruit Trinket with a LiPo battery pack, it was necessary to solder a JST connector to the back of the Adafruit Trinket.

This soldering technique is a bit more advanced and called Solid Mount Soldering, because you are solid 2 pieces directly together.

• Step 1: Tin the connection points on the Adafruit Trinket

  

• Step 2: Secure the JST connector and reheat the previously soldered connections to fuse them.

  

• Step 3: Add a bit more solder to ensure good connection. And voila!

  

5. Connect the battery, attach the Neopixel Jewel again with alligator clips to ensure it's all powered and working.

6. Assemble: WIP
