Optical Theremin – SCHEMATIC

As for the technical components, the hardware was very similar to previous lab work in which we modified to obtain our project. For instance, the corresponding lab (#4) had the output be delivered to an LCD, which ours was adjusted to go to an external speakers. In addition, the major component was a “Guwoops” light sensor which helped to make the conversion.

Optical Theremin – Code Snippet

From our project, the interesting thing about our code is how the output signals are converted into realistic musical notes. The original approach we were going to use the received signals as a corresponding output using a speakers. But, we actually decided to create a realistic version which takes in the signal and translates them into real-world musical notes; therefore that is the most interesting portion of our code. The above photo only portray the first few conversion because including more would just be repetitive. Also, all the code is a series of if statements which tells certain signals to convert to particular musical notes.

Optical Theremin – BIG PICTURE

The proposed idea was to create a Theremin, an electronic musical instrument which is used with only gestures and no physical contact. The goal of the project was to successfully implement the idea while only using the knowledge from the previous lab work and creating a successful product. Therefore, the equipment necessary to complete the project was Atmel Studio and certain hardware components such as wiring, resistors, and amplifiers. As for the software aspect, the concepts of a previous lab were used to implement the proposed idea due to the similarities of the two. As a result of the effort into the project, the goal was accomplished as the Theremin was fully implemented. It was successful because of the way each gesture creates specific musical notes.
