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;
