Spinner Controller

A spinner controller with 3 mouse buttons.

The spinner generates X-axis mouse movement when the knob is rotated, and the buttons generate mouse events. Intended for use with gaming consoles or computers that accept USB mouse-like devices as inputs.

In addition to the printed case and knob, you'll also need:
* a BQLZR 600P/R rotary encoder: https://www.amazon.com/dp/B00UTIFCVA
* an Arduino Pro Micro or equivalent: https://www.amazon.com/dp/B012FOV17O
* three 24mm pushbuttons: https://www.amazon.com/dp/B07X242Z4D
* four 6mm M3 bolts
* six ¼" nuts or similar-sized weights (optional, depending on your gaming preferences)

Assembly is pretty straightforward:
1. solder the header strips onto the Arduino _pointing upward_
2. program the Arduino
3. mount the Arduino in the case (it's a tight fit, and could probably use a heavy double-sided tape to hold it in place)
4. bolt the encoder to the case top using 3 of the bolts
5. connect the encoder to pins labeled 2,3,GND,RAW (whi
