/* BASIC 2 SSR TIMER
 ***************************************************
   WIRING:
   5v pin on the Arduino to DC+ on the SSR board
   GND pin on the Arduino to DC- on the SSR board
   Pin 6 on the Arduino to CH1 on the SSR board
   Pin 7 on the Arduino to CH2 on the SSR board
 ***************************************************
   FUNCTION:
   The Arduino LED (connected to pin 13) will flash briefly
   to indicate SSR 1 is on, at the same time SSR 1 will turn ON.
   After a brief interval (aproximatley 1/3 second) the led will flash again, at the same time SSR 2 will turn ON.

   About 1 second later, both SSR's will turn OFF and the cycle will repeat.

   If you open the Serial Port at 9600 Baud:
   You will see a text confirmation of when an SSR is ON or OFF
   You will also see the TX Led flash briefly when the serial lines are sent.
