RGB LED Projector Christmas Hack

RGB LED Projector Christmas Hack  

Last winter I had an ugly plastic snowman out in the yard front with the brightest fluorescent bulb in it that I could find – it was bright but boring. After doing some cool effects with this Jack-o-lanterns using RGB LEDs was looking to scale things up and put some fancy lighting inside the ugly snowman this year.

When I started sourcing parts, it seemed more economical just to buy a 20W RGB LED spotlight out of eBay for $ 22. I looked up and down to see if anyone had a single notch there to liven up the light without having to stand there with the IR remote. Unfortunately, I did not find an easy and fast hack, but I advanced and ordered the light anyway.

My thoughts were going to use an Arduino Nano to “decode” the remote supplied with the projector and then program the Arduino to be a clone of that distance and automatically change the projector. To my delight, the project was very simple to throw together and is superb! I added a “selector” so I could have three different lighting modes. I have Christmas colors on a fashion, then a winter use theme after Christmas and last a green & gold mode for when the Green Bay Packers play!
