Phone Cleaner

When I was a third-year interaction design student, I was assigned to make something utilizing the Arduino Uno with only one input and output, so I came up with the idea of an automatic phone cleaner.

An LDR sensor is located on the surface of the box. When a phone is placed on the box, the LDR sensor detects a change in light, causing the servo that holds the microcloth to revolve.

This will allow the microcloth to clean the phone's screen.
