Make an Arduino Light Painter

By setting the exposure rate of a camera to a very long period, you can capture movement of a single object over a period of time for some interesting photography ideas. And by use LEDs programmed to change after a certain period of time, you can use this display to make all sorts of effects, as demonstrated by Andrew Mulholland. 

Andrew's system uses a python sketch on a host computer to process an image file and create an Arduino sketch that contains the image data. Once uploaded, the sketch controls an RGB LED strip which is moved across during the photography process. The single exposure can then capture a representation of the original image, for example:

For more information on how to make your own light painter, visit Andrew's github page. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

If you need to add external hardware or devices to your next Arduino project, you'll need a protoshield to mount the external circuitry. In doing so, consider our range of ProtoShields. From the tiny LeoStick to the Mega we have a wide range to suit your application.
