Step 20 - Connection Schematic

Use this schematic and refer back to the first one in Step 10 to see how to wire the Arduino. Either an Arduino UNO or Diecimila will
work. Also, refer to the connection key at the top of the picture, as this really ties both schematics together to make things easier for
you.

Special thanks to MAEWART for his translation to Arduino, and CHR for his invaluable guidance and schematic.

Step 21 - Connecting the Arduino

Use two female headers side-by-side to act as the port to your controller. This port will have wires running from the Arduino to the
controller so it can receive data. Refer back to the first schematic to see how it should be wired. I started by naming pins 1 and 2
across from each other and having the odd and even pins on separate headers. In addition, there will be two status LEDs that can be
used later for debugging. This port will send information to the address selector and to the chips connected in parallel.

Crimping won't be necessary.
