For a midterm project Borna, Jay and I are creating a circuit of lights and sound that turn on and off in a looping sequence. This is an attempt number one to illustrate the general concept.
We are rigging a circuit of 8 lights and thinking about using Piezo Buzzers in the mean time to create sound. The Arduino will allow us to control what lights will turn on and off. We are thinking about using this electrical impulse later as a switch to trigger a more intricate sound patter.
Later on the potentiometer will be swapped out by two photocells that will detect the movement to trigger a switch in the direction of the blinking LEDs and sound.
Here is a simple prototype of the circuit:
