I designed in two variable push buttons using hall effect sensors, two potentiometers and two pushbuttons.
I got my board back a few days ago. it looks good!. I am still waiting for some parts and I am in the process of programming it while I am waiting for the parts.

does anyone have experience with proportional hall effect devices. I would like the output to be linear to the distance, but the measured voltage is proportional to the magnetic flux, not the distance. does anyone know the calculation, or can anyone help me to create a lookup table?
thanks
