If I am using a continuous rotation potentiometer on a pulley, and I want to use an Arduino to convert this reading into an angle as part of an angle control system, then what are the limitations for how fast the pulley can turn? Specifically, if the pulley is turning at 450RPM, will a potentiometer be sufficient or will I have to use an encoder? I am just worried that the faster it is turning, the more noise there will be. I'm also worried about stray capacitance's preventing the voltage from changing to rapidly. On top of this I will have to use a low pass filter to filter out the noise, which may start to filter out the actual signal at high speeds. So what is the maximum speed (RPM) that I can still read angle data from with a continuous rotation potentiometer and arduino.
