This program uses three potentiometers for RGB control and displays the resulting color on an RGB LED. - fyemane/Arduino-Control-RGB-LED ...

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 ...

This LED DIMMER is an Arduino Uno based PWM (Pulse Width Modulation) circuit developed to get variable voltage over constant voltage. The method of PWM is explained below. Before we get start building ...

This project uses two Arduino boards to control the speed of a DC fan using a potentiometer. Three LEDs indicate different speed ranges: red for slow, green for medium, and blue for fast. The serial ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

LED dimmers are like $3 on AliExpress, but yeah that's much more than a potentiometer. On the other hand they handle 12-24V and like 6A of current. You can sink that kind of power into a pot.

While we’ve seen a great deal of innovation in areas such as digital controllers, the interface between the physical dimming control and driver ICs remains complex. Typically, a potentiometer or 0-10V ...
