Dilate your N64 control stick to a certain distance after a threshold distance

N64 Dilation Threshold Mapper

Designed to dilate your N64 control stick after a certain threshold to a certain radius / distance.

Programmed for the Arduino Nano.

Modifications

Modify THRESHOLD to change when the dilation kicks in.

Modify EXPAND to set the radius the coordinates dilate to from the center.

Pins

By default, PIN 8 is your N64 console data line, and PIN 10 is is your N64 controller data line.

Hook ground for both the controller and console up to ground on the Nano.

N64 controller power can go into 3.3v, or take power from the N64, however you wish (I use the Nano's 3.3v line)

N64 console power can either go into the controller, or be left loose.

Use a logic level shifter so you're not sending 5v logic back to the N64/Controller from the Nano.
