 +=== Analog Direction Inputs ====
 +
 +Potentiometer inputs are 0-100kohm, linear. Directional inputs are read by a RC delay circuit, i.e. the time it takes a capacitor to recharge after being discharged determines the potentiometer positions.
 +
 +    * North=0 ohm between 5V and pin 6 (or 13)
 +    * South=500 ohms between 5V and pin 6 (or 13)
 +    * West=0 ohm between 5V and pin 3 (or 11)
 +    * East=500 ohms between 5V and pin 6 (or 13)
 +
 +=== Buttons ===
 +
 +Button inputs have their pins held high by the computer, and are pulled low by the joystick when activated by the user.
