Calculations were made by taking the measurements of the room which was 21x22ft and then finding the area as in a circle (using 10.5 as the radius) and then dividing out the area into separate "bubbles" and then finding the diameter of each bubble and using that to input into the "how far away" individual space each one had.
We sewed cloth to the top of the hat and had an opening large enough for all the material to fit into and tried it on to see if the sensor would reach the front of the hats. We tested the chords and the batteries to each one also.
We did run into a problem of not having enough batter plug ins for the arduino because we took the pack that had 2 of the right plug ins but the other 3 had female inserts instead of the plug in and found some that other students took but were not using. We used electric tape to secure the chords in with the arduino and the sensor.
