Diary Switch

Concept

The concept for this switch is derived from the idea of bookmarks. In this case, when you close a book, there is a light indicator. I made this as a motivation to write poems in an orderly manner before sleeping every night.

Circuit

The switch makes use of a simple circuit that introduces an opened circuit when a book is opened and a closed circuit when the book is closed. See below for circuit diagram.

Remarks

The assignment gave me a keen understanding of how the Arduino breadboard works as I needed to come up with a way to separate the circuit without removing wires from the Arduino Uno board. Overall, challenges I faced was coming up with a creative switch idea.
