RGB LED Lamp

This is the first type of my Skyline Lamp. The circuit therefore the code that works the microprocessor were all developed utilising the Arduino environment after which once I happened to be happy everything worked as I wanted it I made my personal circuit board utilizing an Atmel ATMega168 microprocessor working my rule to manage the twin RGB LED's. The test variation made use of 4 LED's but we was able to discover a supplier of great brilliant RGB LED's which means this final variation utilizes simply two.

The code is defined to randomly select two RGB tints (256 values per color station) after which gradually morph through the last set of tints into the new set with a 10 moments delay inbetween the transitions.

Version 2 for this includes a TLC5940 processor chip allow a much smoother change. The PWM on the AVR gives you 256 greyscale measures whereas the TLC5940 provides you with 4096 offering a far smoother control. You also obtain the capacity to get a handle on 5 seperate RGB LED's from a single chip in comparison to 2 straight from Arduino making use of PWM (although there tend to be ways to simulate PWM on various other Digital I/O lines in computer software).

I adore what sort of lights give a misty impact into rear buildings making all of them seem like they've been drifting in a-sea of colored mist. The video does not get it done justice. The lamp seems far nicer in actual life.

The skyline will be based upon Liverpool. These lights are around for sale, with a skyline of your choosing, upon request.
