Electro-Mechanical Based Automated Whiteboard Wiper

Abstract

Whiteboards although not new, form the basis for an effective learning in organisations and the educational sector of technology.The most common technique of erasing a whiteboard is by the use of a whiteboard wiper 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 labour 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 on the high side for most institutions. The need to save time, funds and effort in schools, offices and various other areas where boards are applied is exceedingly growing and through the use of an automated whiteboard wiper, this can be wholly achieved. In this paper, we design and construct a white board wiper that will completely wipe clean the board after being used with the aid of a push button. The Whiteboard Wiper is a purely electro-mechanical automated whiteboard erasing system, which incorporates a logic gate based control circuit and a mechanical system that will allow for adaptability to various sizes and is reasonably affordable.

Effect of Visual Literacy on the Academic Achievements of Students in Computer Studies in Selected Secondary Schools in Enugu State

“…he use of instructional materials such as visuals is very important in modern day reality education due to their potential to enhance students' understanding of concepts easily and clearly in the classroom. There is a universal recognition of the need to use visual media or technology in education (Aduwa-Ogiegbaen and Iyamu, 2005;Onyema, 2019;Odiase, and Okoli, 2016). The importance of visual literacy in contemporary culture is changing what it means to be literate in the 21st century (Hattwig et al, 2011).…”
