Using a sensor to measure an angle A potentiometer or potential divider is a device, which can be used to measure certain type of data. It consists of a moving contact, which can pass along a surface of high resistance. When it does this the resistant output changes and as a result this can be used to measure things, such as distances or angles, as long as the device can be applied to either a rotary potentiometer or liner potentiometer. Current I = V/R V=voltage R= resistance I have researched that radio and hi-fi systems rely on potentiometers to adjust volume levels. On an old radio there is often a scratchy sounds as you turn the volume knob. This is because the signal from the radios is controlled by tapping off part...
