Hi i am working on an instrument, i want it to active a sound, but not repeatedly as it happens now, if any of you has an idea of how to fix it i´d appreciate it.
Each sound is activated by a bright light on an area, but if the light stays on the area for more than an instant, the sound repeats infinitely and i don´t want that.
THis is the code, if you put a file named notes 1.wav (notes 2, etc...) on your folder you should be able to test it and se the problem.
