The wiring for this project is fairly complex.

For a double-sided wheel, use six LED strips arranged in pairs. The two strips in each pair are wired identically, so the left and right sides of your bike will show the same image. Treat these like one double-sided strip once they're connected.

Working from the IN end of all strips (arrows pointing away from your solder joints:)

• VCC (red wires) connect all together and to VBUS on the USB breakout
• GND (black wires) connect all together and to GND on the USB breakout, and also to G on the Feather
• CI (yellow wires) connect all together and to SCK on the Feather
• DI (green wires) connect in pairs, then the pairs are connected to A1, A2, and A3 on the Feather

Use either Stemma port on the hall effect sensor to plug into the Feather's Stemma port.
