Design and implementation of an automatic whiteboard eraser.

Abstract

Whiteboards form the basis for effective learning in organizations and the educational sector. The most common technique of erasing a whiteboard marks is by the use of a whiteboard duster which is a hand held object manually controlled by the student or teacher. Although the type of material used in wiping the board has evolved, the manual labor is still a constant factor. Technologically, improvements have been achieved in this area where we have the Interactive Whiteboards. However, the cost of acquisition and installation is high for most institutions. The need to save time, funds and effort in schools, offices and various areas where whiteboards are applied is exceedingly growing. Through the use of an automated whiteboard eraser, this can be wholly achieved. This report describes the design and construction of a white board eraser that completely wipes clean the board after being used with the aid of push buttons. The whiteboard eraser is a purely automated whiteboard erasing system, which incorporates a logic gate based control circuit with Arduino at mega 328 microcontrollers and a mechanical system that allows adoptability to similar sized whiteboard and is reasonably affordable. The system is designed to increase the productivity in teacher’s delivery during classroom seasons, by reducing health risks, saving energy and time for the instructor.
