 *
 * Description: This program will produce a single 10ms square wave tone on a speaker via 
 *                  output on PORTC bit 0
 *
 * Input: No user input. 
 *
 * Output: A 10ms square wave meant to drive a speaker

// The setup() method runs once, when the sketch starts

} // end of setup function

/*******************
* loop()
*
* Description: Set pin C0 high, wait 5ms, set pin C0 low, wait 5ms, and repeat
*
* Note: The while(1) loop isn't strictly necessary as the loop function gets repeatedly
*        called by the Arduino overmind
*
* Inputs: None
*
* Outputs: None
