Abstract
In this paper, we present a computer appliance, which is intended for remote control and monitoring of multimedia projectors. The computer appliance is developed and embedded in Novosibirsk State University of Economics and Management and provides easy and unified access for different multimedia projectors with an infrared receiver. The developed computer appliance allows potential extension in order to control other devices with an infrared receiver (e.g. air conditionings, plasma display panels, DVD-players etc.). The main part of the computer appliance is an Arduino microcontroller with an infrared transmitter, an infrared receiver and a RFID-reader for users’ authentication via demonstration an electronic pass. The microcontroller is connected with the personal computer, which, in its turn, is connected with the multimedia projector. Also, we developed special software for this computer, for the microcontroller, as well as for the server, which is intended for centralized control of all the available projectors.
