opened arduino object
put on the IR LEDs but now the thresholding etc will have to be changed to match with it
improved threshold and now pupil is properly detected
stable
changed time values to be able to initialize t=0 just before while loop
added a button to the thing to excite the pupil
added links to the matlab/arduino page
added callback to external m-file to put on the white LED. it does work but the problem is that it cannot be called from the while loop
added excitation m file
