Using a sound trigger to capture lightning strikes is counterproductive. Using an IR sensor to measure the ambient IR, then trip the shutter when the IR spikes up works a treat, though. I built a variation on the Camera Axe last summer, and have been using it to take daylight photos of lightning strikes like this one.

I agree that the Arduino is overkill for a basic sound trigger - but projects like the Camera Axe make a lot more sense. I use a variation on the Camera Axe for photographs of lightning among other things.
