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.
I’ll show you a very easy technique for taking highspeed photos. For this tutorial you don’t need any special equipment, just the cam and your flash.
In Lesson 1 we saw that the main problem with short shutter speeds is that you haven’t enough light. Lets have a look what happens if we use a flash.
