First of all, sorry for the English If anything is incorrect.
Thank you jremington! You Said "picoseconds If used properly". That means there is some way to speed the Rise time of this component, for example? Reducing 7us to Something faster? How?
The sensibility of the component is "fixed" or adjustable as well? How? I'm asking If It can be regulated for the amount of Lux received in order to switch.
Wawa,
The Beam break system was the First Idea when I decided to do the project. It is a simple way to do It, and it's called "Framed Laser Harp". That requeries a large structure above the lasers, since I'm going to play standing. This method prejudice the transportation of the instrument to other places... My project is the "Frameless" type.
I don't know If It Will works, but the glove's function is exactly to reduce the ambient light problem. Imagine that you have your hands turned to the floor, with the sensor "looking down". That way the sensor doesn't receive direct light...
The harp Will have 8 string, 8 lasers, and a pedal to change octaves. The system turns ON and OFF each laser in a sequence. The code tests If the sensor received light and look for the laser that is ON in that moment, in order to know which note It has to play (that's why I need fast response). It is already working with 2 strings, but with more, the delay in code turns to be a problem.
