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;
