Exploring Sound with Arduino


I was able to get a hold of multiple discarded speakers from the back of a television and thought “Well hey, I know how to put these to good use.”

The left and right speakers each have 4 pins that are connected to a single 8 pin connector. It’s easy to identify which wires go to which since they are grouped together and color coded. I wanted to test both of their functionality.

I decided to upload Fur Elise to my Arduino using the code posted here .

If I wanted one note to play on one speaker and then switch to the next speaker, I would have to manually write out each note. Just as a demonstration, I manually switched the hook-up wire back and forth in the same pin on the Arduino.

Here is a video demonstrating the functionality of both speakers.
