Hello I have the identical problem to the one described in this thread: http://forum.arduino.cc/index.php?topic=145535.0
I want to connect a potentiometer to a foot pedal but the range of movement of the pot will be limited to about 50 degrees. Is there any way to make this deflection produce a full 5V change in the output?
In the thread above, @Grumpy_Mike suggestes "using a reduced referance voltage to get the full swing from your reduced angle of movement".. I'm not sure what he meant by that.
