Test the Capacitance

We tested three types of capacitors:

Small:
A) 0.3-5pF
B) 1.0pF

Medium:
A) 3.0-36pF

Large:
A) 10-120pF

on a breadboard and a perf board, and the values of the range changed significantly that we had to go back to the breadboard. We're also not sure if it was the thicker wire that changed the range of the RFID antenna.

Next Steps:

(Before Show):
- We are also going to build an LED indicator into the shelf.
- Add code so it records timed-responses.

(In the near-future)
- Think of orientation of the shelf so that it could read tags perpendicularly.
