This UV Exposure Box Timer project is a project that Charalampos Andrianakis built when he needed a timer for his UV Exposure Box. The project consists of a few push buttons, a few 7 segment digits and a relay. Best of all it is all controlled using a microcontroller which means that it can be custom programmed to do almost anything. Since there is a board created I can see how this simply yet flexible design will find its way into may future applications.
