Automatic whiteboard cleaner
Abstract
Whiteboard had been used widely in the schools and universities. Unluckily, the
whiteboard always left unclean, as the teachers need rush to the next class since it need to be clean manually. As a result, this project had been introduced to solve this problem. The automatic whiteboard cleaner is the project that based on the hardware and software. This is a machine, which can clean a whiteboard with a single press of a button. The duster bar that made from aluminum will move from left to right. The
automatic whiteboard cleaner will be supported by DC motor to ensure the duster bar is
moving. Besides, two limit switches are used to detect boundaries of the whiteboard. So
when the duster bar touches the limit switches, it will stop moving and return to original
position. A PIC18F4580 microcontroller that is programmed in C language is the main
part of this machine. The AutoCAD software is used to design the whiteboard prototype
only then the prototype is fabricated while MPLAB is used to run the microcontroller
program. The advantages of this machine is it only use a DC motor and takes shorter
time to clean the whole whiteboard.
