During the process of creating methods to synchronise light with low-frequency audio, "bochovj" has documented various methods of capturing, amplifying and analysing sound with an Arduino. This includes experimenting with op-amp amplifier circuits, transistor amplifiers and also microphone breakout boards.
Their notes also include digital processing ideas and other thoughts. For those with an interest in ADC, audio analysis and the curious, it's an interesting article. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
If you'd like to learn about Arduino - but not sure how to start - then the best way to learn is with our Experimenter's Kit for Arduino:
The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects!
