Sending sound signal of computer's sound card to arduino how can i send the signal of sound card to arduino? I want to send sound signal of computer's sound card to Arduino just connect a wire from card to Arduino.. and then i will process it by programming of Arduino after that processing the signal will send via wifi... this is my ideal idea.. how can i do this thing? can i interface Arduino via sound card output pin/jack? can i catch the signal of sound card in Arduino?
Did you a look at this ?
Don't expect to play good quality audio through an Arduino, it is not powerful enough for that. Also the Arduino's AD converter is way to slow for anything but telephone quality audio !
