This is my first post, i have some arduino borads, and some arduino stuff, i have readed a basic book for programming, and do basic things with arduino boards. I have been writed post because i want to do a digital volume control with arduino. My idea is the next (and then please say me if its possible or not):
Like a mixer, i want to create a hardware with arduino that control the sounds, digital sounds of my pc. To specify what i means with sound, i want to say the sounds of programs, music, or my microphone like volume mixer integrated in the windows SO but in hardware.
I dont know how to program that idea or how to create with arduino hardware. Some one can say me how could i do, or show me post or page to learn to program that or something.
