Abstract: This project is about finding a real time solution for the problems caused by the chalk pieces used in the class room. To overcome the problems that are faced daily by the students and faculty, the project entitled „BLACKBOARD CLEANING AID‟ has been suggested to automatically erase the blackboard. It is seen that while cleaning the board, faculty and students often have to cover their mouth with one hand while cleaning the blackboard. So we decided to implement our course study and some extra knowledge and with the help of electrical and mechanical concept our project came into picture. The project can clean the blackboard automatically and reduces the time consumed by in hand erasing. As the name suggests our project basically works on combined principles of mechanical and brief knowledge of electronics. The instrument moves forward and backward erasing the board and collecting the dust automatically from the erasing material due to the rotation of the roller. This project is implemented to make human work easier and can reduce the use of human power because of its potential applications. Thus the device avoids the dust flow in the environment and thereby providing good solution for the problems faced by the student, faculty and other electronic equipments that are used inside the class room in a cost effective and time efficient way.

cancer, dust allergy etc.,. The design and usage of a remote control to motorized the white board cleaner. These researches consist of four modules the remote control and transmitter module, the receiver module, pulse generator/ control module and the cleaner module. The remote control unit is used to control the speed and direction of the cleaner. The system is more efficient and flexible. By using a simple circuit than a micro controller circuit, we are able to make the operation a little less complex and a more efficient. The main aim of our project is to save time and energy. In earlier days writing was done by sand, slate, walls, and chalkboards. It‟s highly impossible to spend our time always in cleaning of the white board and absorbing dust. Instead of this, we can control the D.C motor so that the black board can be cleaned. This indeed saves valuable time. We can do by sequential coordination and by the use of forward or reverse switch control. It is highly useful, as it possess various advantages. The conventional black board is still largely in use in many sectors. In the most recent times, processors have found great applications in the field of electronics engineering and automation. Dust collection is a major problem with Chalk boards, and this is a problem essential to be rectified because of the various health hazards it brings with it. The best way to do this would be a vacuum collection system within the cleaner itself. This helps trap the dust within the dust collection system itself as well as not make the prototype unnecessarily bulky. An automatic blackboard duster is a device that is generally used to clean board automatically with the help of duster. By the use of this automatic blackboard duster we can save time and energy. It is a new technology that is generally used now a day. A device for automatically erasing a
