The light painting devices houses an AVR microcontroller and uses Bluetooth LE technology to establish a form of communication with the Android application. This report provides a detailed documentation on the development of the smartphone controlled hand-held light painting application. It will feature the various aspects and approaches, hardware and software, as well as changes and enhancements along the way leading to the final product.
