A Remote Controlled Motorized White Board Cleaner

Abstract

Teaching and learning in schools have been done over the years by writing on boards and different methods of cleaning writing boards have been developed in the past. This paper presents the design and construction of a remote controlled motorized white board cleaner. The system consists of four basic units: the remote control and transmitter unit, the receiver unit, pulse generator/ control unit and the cleaner unit. The operation of the system is centered on AT89552 microcontroller and is such that when the remote button is pressed within the range of 20 meters to the board, the cleaner cleans the board. The speed and direction of the cleaner is also controlled via the remote control. The system makes the teaching efficient and flexible.
