MusicBox: Mapping and visualizing music collections. Triggering a Camera’s Flash with Sound and Light. Update: Check out my latest Camera Axe project for a much more robust device that handles this or my store where I sell the Camera Axe.
For those just wanting to see the pretty pictures, click here. This article focuses on making the sensors used to trigger a camera’s flash using a microphone or a cheap laser pointer. Since I’ve already described how to do the actual firing of a camera’s flash here I won’t focus on that part of this project today. There are a lot of places on the web that describe how to trigger a flash with an electrical circuit, but I feel that using a microcontroller like Arduino offers big benefits.
