Simon Inns @ Waiting of Friday builds a cool VU meter using RGB leds. RGB leds are controlled by 3 TLC5940 LED driver chips and PIC18F2550 microcontroller. Source code and schematic is available on the link below. [via]
This project creates a RGB LED VU Meter which is controlled via USB by a Windows 7 or Vista host machine. The demonstration board consists of a 5V regulator (switching), a PIC18F2550 with the required USB components, 3xTLC5940 16 channel serial LED drivers with PWM and 16 high intensity RGB LEDs.

This project is an RGB led controller based on Microchip PIC18F2550. Color change can be depended on temperature or CPU load, or screen. Controller board communicates via USB with setup application that helps change the color of leds. Schematic, code snd PCBs are available on the link below.

Step-by-step, easy to follow instructions on the building of a LED Rainbow RGB LED PWM Controller. Only a minimal amount of parts are needed, along with a PIC processor, and you can construct one of the most amazing LED controllers available.
The system is capable of driving either RGB LEDs, or individual Red, Green and Blue LEDs to produce stunning effects.

Follow these simple instructions to build you own RGB LED PWM driver. This easy to construct, versatile driver board will allow you to make your own RGB LED driver that can be built into all kinds of lighting effects. It doesn’t need DMX or any other external controller to operate, just a suitable power supply. The firmware is available as a free download and the sequences fully customizable, so if you have access to a PIC programmer you can create your own range of sequences for use with the kit.

This RGB LED controller kit is somewhat different to other offerings on the ‘net. Whereas most others use a single button to step through short pre-programmed loops this controller is intelligent enough to understand different colour palletes and generate colours in real time using a huge 8 million bit randomiser. It lets you choose a colour pallete from sharp vivid colours to soft pastels and the speed and way it will move between them. It also has a selection of other effects thrown in just for good measure, and remembers it’s current settings when the power is turned off.

Control the colour of a powerful LED light beam with a remote control, store the colours and recall them at will. [via]
With this thing I can control the colour of a bright light into many different colours using the three fundamentals colours : red green and blue. Adding them toghether with different intensity can yeld very great a range of colours from the visible spectrum.

This RGB light I designed and built a while ago. A large spectrum of coloured light can be made mixing light from bulbs coloured in red, green and blue. So, this one is not based on LEDs but it’s based on 3×60W 220/110Vac light bulbs. Also, it has a remote controller to change intensity of the three bulbs, store and recall preferred hues, turn the thing on and off.

This is a remake of the fireflies which I did a year ago. I was always fascinated by the emergence of patterns. One I like most is the synchronization of hundreds or thousands of fireflies. First they flash randomly but after some time and influencing each other, they flash in sync.
This circuit simulates fireflies with small microcontrollers. Note that every firefly acts completely autonomously, it is not a preprogrammed pattern. It is a self organizing system.
The NG version uses a small PCB (Printed Circuit Board) and a RGB-LED.

The module consists of a Atmega8 microcontroller. It uses PWM to control 3 different LED’s found in a RGB Led. Because it uses PWM to control the 3 colours we can also control the brightness of the colours. This allows us to create various colours using the three original colors (Red,Green and Blue).

If you want to learn how to control RGBLED this is the right website that you should to visit.Here is the sumary about this website “The RGBLED and mRGBLED controllers allow you to control the color of RGBLEDs. This might sound trivial, but it actually takes a lot of resources to let you be able to set an RGBLED to any color you’d like. In addition to just lighting an LED up with a given color, these boards also let you install a color or setup transition/animations effects. They are easily controller via an RS232 connection (serial port) or an SPI connection (logic level).The boards can be built reasonably inexpensively and there are PC boards available for either model. All source code for the onboard PIC processor as well as the software for configuring and using the controllers is available. The protocol is a simple protocol well documented.” [via]
