Serial communication: 9:00-12.00

1. RS-232
   1. Baud rate : One baud is one electronic state change (one bit) per second. (e.g. Serial.begin(9600))
      
   2. Parity : odd, even, or none (e.g. none parity)
      
   3. Data bits : 5, 6, 7, or 8bits (e.g. 8bits)
      
   4. Stop bits : 1, 1.5, or 2 (often says true = 1 stop bits)
