This is the eagerly awaited 3.0 version of Photoduino. Photoduino is an open source camera controller based on the Arduino platform which you can use to automatically take pictures with your DSLR camera.
It serves as technical support for shooting high speed photos but you can also use it as an intervalometer to make Timelapse videos or for animals and insects photography.
Photoduino is an electronic circuit that is placed on an Arduino board as a Shield taking all the inputs, outputs and power pins. It has all the necessary electronic components and connectors for connecting the camera, flashes and sensors. You can control the shutter and camera autofocus, and you can also trigger two flashes. It also has a sound sensor, a shock/impact sensor and a laser or infrared barrier that can be used to take pictures when you register an event on any of the sensors. The configuration is done entirely through a small LCD screen using only two buttons, so it works independently without the need for a computer (except for firmware updates).
This system currently supports a wide range of DSLR cameras with a remote shutter cable connector.
Both hardware and firmware are completely open (like the Arduino platform on which it is based) and it is released under an open license.
