 * ToDo:
 * -Code in pins to use
 * -create function that will play a tone out of buzzer
 * -add led to light up when buzzer it played
 * -Create functions to light up neopixel strip and ring

While designing this I decided I would focus on the wiring. I had begun simply by getting two touch sensors to work with two neopixels and buzzers. The image below shows this beginning phase.

After this I had decided to follow up by completely wiring all the components and getting the resulting image.

The next part of this project was trying to come up with a method of containing this mess. I decided to use legos because they are easy to acquire and allow for flexiblity. I had begun by building around the arduino board.

Then once the outside had begun to take shape I began to lay down the ground work for the different components. In the image following there is a raised platform that is meant to hold up the neopixel strip to allow for easy visiblity and a gap in the side for the touch sensors to peek out of.
