Abstract:

Report has been written on design and fabrication smart board cleaner to introduce a new advance mechanism for erasing the board. In previous project, the mechanism used for erasing the board was belt drive, controlling it by switches. So to erase the board, he/she has to come near the board and press the button. Hence, this makes discomfort for the lecturer. Along with this erasing was done from one side to another side. So it was not possible to erase section wise or partially. The above mention problems/ limitations of previous project is resolved in our project by controlling the project by mobile phone at a range of 10m from board as well as we can erase the board partially by dividing the board in four sections and duster into two parts. The significance of our project is that the project can be controlled by lecturer anywhere from the classroom. Electronic kit used is portable, light is weight, compact in size and for accuracy Lead Screw is used.

Introduction:                

A smart board cleaner is a device, which is used to clean the board automatically with the help of duster. By using this device we can not only reduce human effort but also save time. A device for automatic operation, duster is mounted longitudinally which slides over the two horizontal rods and forward, backward motion of duster is provided by rack and pinion mechanism. In this device, the erasing action of the duster is controlled by the mobile application used in mobile. Mechanism is important in this project ,so that this mechanism can be applied on blackboard as well as whiteboard .this board is divided into four section A, B ,C, D as a four quadrants, erasing action of each quadrants is controlled by a microcontroller (arduinouno).This device can be controlled upto a range of 10m by using mobile. In present automatic board cleaner, switches are used to erase the board. So, if the teacher is far away from board he has to come towards the board to switch the button to erase the board .hence, our device can erase the board. If the teacher is away from the board by using mobile application.

LITERATURE SURVEY:

This section includes background and various systems for cleaning the whiteboard and blackboard. Different research papers are referred to study the different systems and different mechanisms.Different research papers are referred to study the different systems and different mechanisms. This machine can operate in three selectable opera table modes. Initially the board is divided into four sections, or four quadrants. So, to erase these four sections by duster we are using 5000rpm two D.C Gear motors to move duster in horizontal (x-axis) direction. To move the duster in forward and backward motion 10rpm motor is used. ATMEGA328P microcontroller is used to control the motion of duster. The paper puts forward a kind of mechanism design scheme; the mechanism can automatically controlled by using mobile application, this mobile is connected to the microcontroller. In this way, when, the button is pressed in application at a range of 10m, the operation ofthat section is possible.

Advantage and applications:

i.                   Minimize lecturer's effort.

This technique was selected by us by taking into consideration some comfort for Teachers while cleaning the blackboard/whiteboard.

Ii.Reducing health hazards

The traditional blackboard chalk dust is a common problem in the traditional blackboard-eraser-chalk architecture. This operation produced a great deal of dust that is rather objectionable both from the standpoint of health and cleanliness. These tiny particles of chalk may also land on devices or computer equipment that would cause overheating and severe damage. Also in case of whiteboards, Permanent marker will affect someone whose has allergic reaction, possible ink poisoning and side effects from inhaling ink fumes. This is because the permanent ink is made from organic solvent.

Iii.Time Saving

As the manual method is time consuming, implementing automatic cleaning mechanism will definitely save the significant amount of time.

FUTURE SCOPE

· By Application of Gesture Sensor, the whole board can be controlled by using the palm, by showing different gestures different areas of the board can be erased.

· So, different gestures would be assigned for different actions. Hence, to do the project Camera is required for image graphing and a microcontroller (Rasp berry).

· Just like we take selfies in our phone by palm sensor, in the same way we can control the Board.
