Overview

An Arduino recieves commands from the user via buttons and a knob (potentiometer).

The user gets feedback from an LCD screen.

When the selection is complete, the Arduino runs the operation.

A motor turns a threaded rod to move the eraser left and right.

A spring and electromagnet is used to pull the eraser away from the whiteboard when needed.

A pump is also available for a deep clean function, with fluid measurement using a laser.

Parts were selected and mocked up in Solidworks.

Front view of the finished product.

The user interacts with the whiteboard through a system of buttons, a potentiometer, and LCD display.

The display shows different options for cleaning.

A threaded rod is used as a cheap lead screw to move the eraser along the board.

Fluid level was measured using a laser and photoresistor, and a pump was used to deep clean the board with fluid.

A system of transistors and voltage regulators was used to receive signals from the Arduino and provide power to the components .

The prototype software for the Arduino microcontroller is attached.
