Abstract:
Innovation from scrap materials can go beyond expectations. For this reason, the objective of this study is to
create a motorized whiteboard eraser out of a car windshield rubber blade from a broken car. With the help
of Arduino Uno and Arduino Interface, an open-source electronics platform based on easy-to-use hardware
and software, was able to help read the coding and inputs in causing the wiper moves with a switch, battery, and motor. The results of the study showed that the time of executing the command was 0.35 seconds after
turning the switch on, while the distance covered in centimeters by the motorized whiteboard eraser was
75cm. It is also noted that after four rounds of horizontal swiping directions, it had totally erased the writings
on the whiteboard. Further, in terms of the speed of erasing the writing, the shortest time was 0.0852 miles
per hour. Proving its efficacy in erasing various percentages of shaded parts it is recorded that in 50% shaded
part it took a minute and six seconds, while in 75% shaded part it took one minute and 20 seconds, lastly, in
a 100% shaded it could totally be erased in a span of one minute and 36 seconds. As a result, it is
recommended to increase the speed of the motorized whiteboard eraser by utilizing a bigger motor with a
higher RPM capacity. Moreover, it is advised that the whiteboard eraser be improved in order for the rubber
blade to entirely adhere to the whiteboard in order to have fewer constraints on erasing. It is also
recommended that you choose a lighter material than PVC in order for the eraser to operate smoothly. |
