In the process, I learned:
1. how to program a Gemma with CodeBender (even though no ports were detected)
2. how to use a multimeter
3. the importance of using a stabilizer when sewing with conductive thread on a loosely woven material
Unfortunately, I had to learn a couple of lessons the hard way when threads in the stretchy sweater kept shorting out!
In order to increase the versatility of this sweater, I sewed the Gemma to three tiny snaps sewn to a piece of felt. When folded up, the felt supports the battery and fits into the sweater pocket. This connects to three more snaps to complete the circuit.
|I sewed the neopixels to a ribbon.|
Originally, I sewed the neopixels directly to the sweater. That didn't work out well, because I didn't stabilize the back of the fabric first, requiring me to have to rip out all of the stitches.
Afterward, I used what I learned from Adafruit's chameleon scarf tutorial to sew the neopixels onto a ribbon that I later sewed to the sweater using non-conductive thread.
