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]

This page shows you to build a lamp that can change color, and can be controlled by a computer. Simple Python and C programs for your PC or Mac are provided that let you program color patterns into the lamp. Implementing the weather forecast and other ideas are then up to you. Web scraping with wget is easy if you understand a scripting language. The whole project should cost under 100 euro, half of which is for the lamp (glass ball, LED module, microcontroller, and odds and ends), and the other half for the flash programmer if you don’t have one.

The circuit is very simple. The RGB LED is hooked up to the PWM outputs on PORTB1 , PORTB2 and PORTB3 of the ATMega8. There is also a resistor between the LED and the ATmega8 to limit the current to 20mA. There is also a link to the datasheet of the RGB LED that is used in this project.

The code for the fading LED is written in assembler with the AVR Studio 4. In this example the LEDs will fade in and out one by one. The PWM timers of the ATMega8 are used to let the LED’s fade in and out. To use the PWM timers you first need to initialize the timers at the begin of the program code. The speed of the fading in and out can be changed with changing the clock speed of the ATM8.You can copy and paste the textfile into the AVR Studio 4. [via]

ShiftBrite is a simple device I am designing and producing. It allows easy control of a bright RGB LED. The interface is a straightforward clocked serial data line and a latch input. All signals are buffered and passed through for good performance over long cables and daisy chaining many devices. Many ShiftBrite devices can be controlled from any type of controller that supports clocked serial data output, which is practically all microcontrollers and even PC parallel port or FTDI bitbang adapters.

This project is an array of LEDs, sized to fit an alcove in my apartment living room, about 35 inches wide by 58 inches tall. The LEDs will be RGB, with fullcolor pixels arranged 16 wide by 24 tall. Each pixel will be 2 1/8 inches square. There are a total of 384 pixels, and 1152 individually controlled LEDs. The array will be used to display informational graphics, audio visualizations, and tunable ambient lighting.
