Re: Limited OI Range From Linear Slide Potentiometers

The OI doesn't want to see a voltage. It wants to see a variable resistance. You're "tricking" it by using a potentiometer, and you aren't quite tricking it enough. I think you could get it to work better by adding a 22k resistor between the low end of the pot and ground, but that still won't be using the OI input the way it is designed.

Try making the OI a little happier by connecting one end of the 50k pot to +5 through a 22k resistor, connecting the wiper to the joystick input pin, and leaving the other end of the pot open.
