Abstract

Intervalometer or time lapse photography is not very widely used because it requires good planning and a lot of time. Photos are then often put together into a video file which is not a simple procedure. One can buy a wired remote for the camera with time lapse function. But we haven't found one that can be controlled with a mobile phone. In this thesis we are focusing on building an application for Symbian smartphone, rather than the time lapse photography itself. A photographic intervalometer that can be connected to a camera was designed and constructed. The mobile phone and the intervalometer communicate wirelessly via Bluetooth. Mobile phone is used to remotely control the intervalometer. It can also use SMS messages for this purpose. The intervalometer can also be used as a stand-alone device and the user operates it with the built-in keyboard and LCD screen. The aim of this thesis was to explore the possibility of wireless communication and control. This goal was achieved using mobile phone and the Arduino development board which communicate wirelessly via Bluetooth. In the end we got a fully functional intervalometer prototype which can be used to demonstrate how the device works and how it can be used.
