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 ...

Components Arduino Main (Arduino 1) - Controls the LEDs, potentiometer, and L293D motor driver. Arduino Helper (Arduino 2) - Powers the DC motor through a transistor and diode setup. DC Motor with Fan ...

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 ...

I'm trying to dim LED strips, approximately 30ft in length, with hand controls. I've found that regular potentiometers (those sold by Adafruit) max out at about 0.2 W. For whatever reason, the Red ...

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 ...
