To Initialize the Arduino Box:

      if (exist('DIO', 'var') == 0)
               % the exact address can be figured out using http://arduino.cc/en/Main/Software 
               DIO = arduino('/dev/tty.usbmodem621');
       end
       for i = 2:19 % filp all pins to a low state (0V)
           DIO.pinMode(i,'output');
           DIO.digitalWrite(i,0)
       end


To Send a pulse:

TTLpin = 2; % any pin from 2 through 19 can be used DIO.digitalWrite(TTLpin,1); % set pin to 5V wrt to GND DIO.digitalWrite(TTLpin,0); % set pin to 0V wrt to GND


To close the session delete DIO;
