RGB LED Pen for Lightpainting

This is a complete build instruction for a light painting tool that uses an RGB LED controller. I use this controller a lot in my advanced tools and thought a documentary of how this is built and programmed can help some people. This tool is a modular RGB light pen meant for light writing, light drawing and lighting graffiti. It is easy to use because you only have the pen in your hand and you can quickly change the colour.”
