Photoduino is an open source camera controller based on the Arduino platform. Its main purpose is to serve as technical support for taking photographs of various techniques such as: Timelapses, High Speed Photography, Photography of insects and animals, storms Photography or HDR Photography among others. The electronic circuit is capable to control autofocus and shutter of a camera and two manuals flashes. It also has a sound sensor, an impact/shock sensor, a laser barrier and an infrared barrier that can be used to take pictures when an event is registered . The configuration is set full through a small LCD display using only two buttons, so that works independently without the need for a computer connected (except for firmware updates). The system is currently compatible with multitude of cameras but may be adaptable in the future to other models and brands that have remote shutter connector cable.
