In the last lesson I wrote about light barrier. Sometimes there are sensors which are more adequate than a light barrier f.ex. if you want to photography a bursting balloon. In this lesson I’ll show how to use a sound trigger.

In the last lesson we saw how one can trigger a flash with an Arduino. In this lesson we’ll add a light barrier to trigger the flash in the right moment.

In the last lesson I showed how to trigger your camera with a flash. In highspeed photography you often want to trigger your flash (see Lesson 3: Freeze the motion with your flash), therefore I show you how to trigger your flash with an arduino.

In the last lesson I showed what an Arduino is. In this lesson I’ll show you how to use an Arduino to trigger your camera.

As I began with highspeed photography, I bought a cheap sound trigger. Soon I realized, that this trigger wasn’t very flexible – f.ex. I couldn’t set the delay very accurate. I did some research and found out that I need a programmable microcontroller. As I had no electronic knowledge, it had to be something really simple. Some friends have already spoken about that “Arduino”, so I had a look at it and recognized, that an Arduio perfectly fits my needs.
