Abstract This project is a degree project made to give a degree in electronic- and mechatronic- engineering. The assigner HMS wants to expand their test system regarding their products. In the existing test system this is done by a manual control of the products functions. For the assigner the project aim is to in a higher degree than today automate the test procedure and secure the quality. Equipment has been developed in the project that contains a sensor connected to a logic unit which communicates the sensor values to a PC. Measurements show that equipment on a reliable way can measure if the light emitting diodes that are assembled on the assigner product emit light or not. It can also decide if the light emitting diodes shine with red or green light. Advantage with the equipment is the components low price and the easy implement in to the already existing system. This since the communication with the already existing system is done by USB, which is ordinary occurrin...
