I am building a pole position/ off road cab with a raspberry Pi and 360 wheels. I have an analog potentiometer gas pedal and brake set. I use a mini pac for buttons and joystick. What should I use for the pedals. I will eventually get 2 more gas pedals to use for the off road game but I’m starting simple at first.
Several approaches to this:
1. Use your Mini-Pac for the buttons, joystick, and 360 wheels. Use a U-HID nano for the pedals.
- Two 360 wheels are electrically the same as one trackball.
2. If you want to fit all of the controls on one hybrid encoder board, you're looking at a full-size U-HID.
- It's a bit expensive for some people's budget but a very powerful and flexible encoder.
3. You can roll-your-own joystick/button, optical, or analog encoders using inexpensive 32u4 Arduino boards.
- Costs far less than the encoders mentioned above, but requires some soldering skills and loading the desired firmware on the board.

Dedicated admin buttons or shifted functions?
http://wiki.arcadecontrols.com/index.php/FAQ#Number_of_admin_buttonsHow many of each type of control will you need for your final build?
2 - 360 wheels (optical encoder)
4 - potentiometer pedals (analog/gamepad encoder)
__ - admin and player buttons (gamepad or keyboard encoder)
__ - joysticks (gamepad or keyboard encoder)
Based on that info, you can determine how many inputs/connections you'll need.

A 360 wheel is an optical (mouse) control.
- 5v
- Ground
- Two data lines ("quadrature waveforms")
A potentiometer is an analog control.
- 5v
- Ground
- Input for variable voltage from the wiper (center tab)
Buttons/joysticks are microswitch controls.
- Input
- Ground
