1. How can I get the values of the phototransistor when the laser is on and off?
2. What values does the midi actaully send, how does it know when laser beam one has been blocked? Is it like (very simple), if beam one is struck send a certain value (a note) trough the midi output to the computer.
Between, for a green laser beam I am in need of a phototransistor capable to handle a wavelength of 532nm. So 600nm should work, correct?
