Our Project:

For our circuit, we played the Imperial March from Star Wars, and then had flashing lights play after the song ends to represent light sabers. 

How it works:

The buzzer is connected to pin 11, and is connected to the potentiometer. The potentiometer must be turned all the way to the right to allow the voltage to flow through the circuit at maximum. The buzzer reads the code from the arduino and plays the music. After the music code is finished, a loop starts to create the flashing lights that move up and down along the light sabers. The wires are connected to one pin of the LED, while the other is connected to a 220 ohm resistor. The resistors regulate the flow of the current.

Reflection:

I think we did a good job designing an easy code and circuit without any coding experience before. It was hard in the begininng, but as we began to learn more about how to setup the circuits and code it became fun. It was neat to see our circuit come into action when we ran the code. I feel like I learned the basic skills to create new circuits and create basic code.
