The basic idea was to use a LED display programming by Arduino that can display some character with various intensity of flash. Then I saw some Theremin Instructables using Light sensor that made a unique sound when it given the light. Then the idea to combine the both project really made me excited.
This project was made for my own project on campus. It is built since 3 months ago, so there will be some different picture for one part, because it's been fixed from time to time, and continues to have a progress.
This circuit it's so simple, but the process requires patience, precision, and efficiency.

Okay, let's get started.
