Glitch Art with Arduino and LED strip.

I’m working on driving LEDs strip from an Arduino Uno. I setup a small circuit around a TIP 121 and a photo resistor inspired from this post on Dimming a 12V LED Strip With an Arduino.

We the photo resistor input gets too low, I unintentionally send -1 on the pin which is probably interpreted as HIGH and the LED strip flashes. See the video:

I love glitch art.
