FIRST Recommendations:
A.W.G. vs. current in amps.
12 40A

    DB-xx Connectors:
    1.     These connectors are heavily used on the FIRST Computer boards. The 3 typical values of xx are 9( not 09), 15 and 25.
    2.     Typical uses are serial ports for DB-9, and game ports for DB-15. DB-25 serial cables were used for dial-up modems. Each size can be used in many realms.
    3.     This project uses ready-made cables. There are times when one must know pin numbers.
          A plug is pushed into a socket. An example is pushing the power plug on a TV set into the socket on a wall. If one is looking at a DB-15 plug, the pin numbers are:
      •    1            8
      •     9       15
          If one is looking at a DB-15 socket, the socket numbers are:
      •    8            1
      •     15       9

    General Notes:
    • Get Ear Plugs( about $5 at CVS, etc); competitions are noisy++
