A neat and simple microphone breakout board from PMD Way for sound and audio experiments. Use it to detect sounds of a certain, adjustable level and receive a digital signal when the noise level exceeds the preset limit. Free delivery, worldwide. If you are looking to capture audio for processing and need a line-level output, consider the MAX4466 breakout board. Instructions: Analogue mode: Connect 5V to the pin labelled "+" Connect GND to the pin labelled "G" connect your microcontroller's analogue input to the pin labelled "AO" Voltage returned from AO pin is proportional to sound level Digital Mode: Connect 5V to the pin labelled "+" Connect GND to the pin labelled "G" Connect your microcontroller's digital input to the pin labelled "DO" When ambient sound reaches a certain level, the DO will go HIGH (5V). You can adjust the threshold level with the blue potentiometer. Don't forget to check out our full range of microphone boards if this doesn't meet your needs.
