Today we tinker us a driver for RGB LED strips using an Arduino. In addition, we use optocouplers to separtae our Arduino from the control unit with the 3 MOSFETs, which is not absolutely essential, but brings some advantages to the circuit.

A RGB LED Library for Arduino
To simplify dealing with multiple RGB strips or individual RGB LEDs I have written a small RGB library. This includes functions for direct set colors in RGB or HSV color model, and animation functionality of color transitions. The library is in a beta phase, is constantly evolving, but can already be used with absolutely NO WARRANTY.
A TLC5940, 5 RGB-LEDs and an Arduino
The TLC5940 is a LED driver IC, which we use today to drive 5 RGB LEDs with common anode. The advantage of this circuit is that it provides a constant adjustable output current for the LEDs and only requires minimal wiring.
Mood lamp with a digital RGB LED Strip (WS2811/WS2812), an Arduino, acrylic glass and a few parts from the hardware store
Today, we build us an animated and programmable mood lamp that can be nicely used as a functional decoration. This tutorial is understood only as a suggestion, especially the design of course is always in the eye of the beholder.
Briefly introduced: Digital (individually addressable) RGB LED strip based on the WS2811 controller and the 5050 LED
The presented RGB Strip is equipped compared to “normal” strips with the property of being able to control each LED individually, which means that not only one color can be displayed simultaneously on the strip, but even complete color transitions at the same time.
