“We tinkerers have used potentiometers whether it is of a buck-boost converter or simple audio amplifier, and at some point, we struggled with controlling it precisely.
We can get trim pots but setting those regularly is not so easy. Also, there are multi-turn potentiometers available in the market but they are generally expensive and only available in a limited range of values.
So in this Instructable, I will show you how I made a simple mechanism that can be used to turn any potentiometer into a multi-turn potentiometer.”
