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.
