Call it synchronicity, or manually setting a 16-bit number in an Arduino, or how to turn an OLED into a rotary dial... What am I talking about? Well, I was just compiling the blogs pages for the next ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

Gear Potentiometers are also called Thumbwheel Potentiometers. Let’s investigate them. There are many varieties of compact gear potentiometers available. Most of them are single and dual – this time ...

Potentiometers, or variable resistors, are a standard component that we take for granted. If it says “10k log” on a volume pot, than we fit and forget. But if like [Ben Holmes] you are modelling ...

Digital potentiometers are digitally controlled variable resistors that can be used in place of their functionally equivalent mechanical counterparts. While digital potentiometers offer comparable ...
