The joystick x-axis is attached to Arduino pin A0 and the y-axis to Arduino A1, and these are our INPUT. The x- and y-axes are then set as variables for movement.

The arduino R3 pinout includes an IORef pin which will be 5v on a 5v arduino but 3.3v on a 3.3v arduino. Any IC’s on the shield should run at IORef. Report comment. Reply. F says: ...

CGA monitors may not be an amazing technological advance these days, but they can generally be found very cheaply. Additionally, they have a DB-9 connector and work off of TTL ranges (0-5VDC) makin… ...
