I could use help finding parts that fit together better, such as parts that are made for each other, or come as premade as possible (so I don’t have to put them together as much). The best I can think of so far is
- A compass sensor shield that connects to the main microcontroller board. It would be better to get both (the microcontroller and the compass sensor) on the same board.
- About 9 inches of strip lights to create a chase effect (that goes down the part of a costume that covers a forearm), though it wouldn’t be attached to the costume. It would be connected to the microcontroller.
- Velcro strap armbands to hold the above two on the forearm.
- A way to make it so conductors don’t get pulled out of pins.
For wearable projects, I think you’d better proceed with Adafruit Flora. It is Arduino compatible. There are many flora-compatible accessories available. Such as neopixel led rings, gyro, compass, GPS modules etc. You can take a look at the flora projects: https://learn.adafruit.com/flora-geo-watch
