Sound Pass Through using PIC16F877

Another sound experiment was to use the pic as a pass through. Put music in on one side and get it out at the other side. The music is fed into an A/D converter and converted to a digital signal. On the other side of the pic it has to be converted back from digital to analog.

On the breadboard an actual sound source has been connected: a multi band receiver. Which is a big word for a tiny transistor radio, but it can indeed receive multiple bands. None of them with good music though, as you're about to find out. The long wires on the left side are from the Wips628 in-circuit programmer. And low and behold: this actually works!! And not only that, the sound quality is quite reasonable, as you can tell by this small mp3. Okay, I admit, horrible choice of music, but it's radio and I didn't feel like waiting for something nice to come along. And then again: how often do they actually play something nice like Sofa Surfers or Snake River Conspiracy? So let's not be picky. The sound output is very soft, so the volume control isn't really needed at this point.
