Light-triggered relay switch
Version 1 - Last update: Oct 27, 2015

Light-triggered relay switch based around LM393P

This circuit activates a relay switch upon detection of light. Meant for use in DIY high-speed photography, it's purpose is to fire an off-camera, non-synced strobe light upon the detection of a sudden change (increase) in light.
