I combined the Plexi Project (Arduino backlit photo controller) with an artwork is did last year when I first got into LED strips. It’s an encaustic piece that drowns the light to give it a translucent and diffused feel to the light lines. Here’s the assembled piece.
I want to make my Plexi Controller as small as possible. This Arduino project controls the intensity of the LEDs for artworks that are framed with a backlit plexiglass. So I wired a new version of the schematics around an Adafruit Pro Trinket. It’s a lot smaller and has almost all the capabilities of a full scale Arduino Uno.
Here’s the result.
