Round Dial Potentiometers are variable resistors whose resistance can be varied by moving the handle linearly from one end to another. This is item include 50K potentiometers with a common ground. It has a nice big 16mm diameter dial which can be used to manually adjust the required resistance. This potentiometer is popularly used in radios and stereos. This is basically a variable resistor, which means when the handle is at one end the resistance is 0 ohms. Moving the handle towards the other end will change the resistance towards 50K as per the handle movement. Can be easily connected to the analog pin on an Arduino or a Raspberry Pi to get the handle position. But is great for controlling lights or a fan, linear encoder, etc
