Rotary potentiometers consist of a circular conductive track and an electrical wiper attached to a central shaft. A constant voltage is applied to the track; as the shaft turns and the wiper contacts ...
"Linear" can refer to the motion of the slider. Such a device is also known as a slide potentiometer. By contrast, a rotary potentiometer slider twists. Linear/Slide "Linear" can refer to the taper ...
After becoming frustrated with drift in the potentiometers, he set out to outfit the entire rig with custom-built encoders. [s-ol] designed the rotary-encoder based boards around an FPGA.
