Controlling a Stepper Motor with the L293D
This nifty little USB pig-tail adds audio input and output through USB. It's a cheap and cheerful solution for audio input to your Raspberry Pi, and the short cable design means it plays nicely with the other USB ports on a Pi.
After testing a wide range of USB audio dongles, this was the winner through being simple, low on noise and artefacts, and free from pointless buttons, bells, and whistles. The ferrite bead on the cable is a nice little extra.

In Raspbian, this device should show up in the audio control panel automagically (go to the Raspberry Pi menu, then Preferences, then Audio Device Settings, and select USB PnP Sound Device).
We recommend providing a good signal to the input, as it provides no gain/boost for passive mics.
Once you're up and running, record audio input on your Pi, in the terminal, by typing:arecord -D plughw:1 -f cd /tmp/recording.wav
