What Is It

The knob detects the motion of the shaft, like a clockwise or counterclockwise rotation or merely a rotary movement.

How It Works

The Knob converts angular position or the motion of the shaft to digital output signals. The signals indicate if the knob is turned clockwise or counterclockwise. Usually, you can turn it clockwise to increase the value of something (for example, to adjust the brightness of a LED) or turn it counter-clockwise to decrease the value. The Knob can also work a logical input by detecting the presence of rotary motion.
