Light painting, also called light graffiti, is a photography technique where a picture is taken in a dark environment, and light is selectively applied. Here’s a little more explanation of the technique in an article I wrote a while ago on Hackaday. One thing you might notice from that article, or your own experience, is that the lighting tools available are generally adapted from other uses.
But is there was something specifically made for this purpose? Well now there is, the “Light Painters Palette,” which allows you to select colors and lighting patterns via four 10mm RGB LEDs. It’s controlled via an Arduino Pro Mini, so if you’re not satisfied with how everything is set up, you can make changes as needed (code available on here on GitHub).
The kit linked above needs some assembly and you’ll need to provide your own Arduino, power supply, and infrared receiver if you want to use it. On the other hand, if you just want to start painting, it’s available fully assembled and programmed here, though you’ll still need to provide your own remote control transmitter if you’d like to use that feature. [Jdskier1] used the kind of inexpensive color remote that comes with a lot of addressable RGB strips so you may already have one of these on hand. Modes, remote control, and assembly are all shown off in his video found below — and the demo image shown above really illustrates the potential of this little board.
