#142119 - Wrong question!

Hello, how can I connect the 8051 pins to PC's sound card the way it wont burn my sound card? Thanks.

That's the wrong question - it really has nothing to do with the 8051!

The question you need to ask is, "what is the input specification for my soundcard?" - then design according to that.

The soundcard neither knows nor cares what is connected to its input - all that matters is that it abides by the specifications.

You will probably want to use the Line-level input - which will be about 500mV, and an impedance of 10k or so
