Resources and Going Further
Now that you've connected your MEMS microphone breakout, it's time to incorporate it into your own project! For more information, check out the resources below:
- ADMP401
- ICS-40180
If you run into trouble getting, or understanding, an audio signal output from the MEMS mic breakout board, try using a multimeter and/or an oscilloscope to measure the voltage output of the signal in quiet and loud settings. If you're still stuck, check out our forums and we'll help you troubleshoot.
After you've read in the MEMS microphone and have a good handle on the signal output, you're ready to start using it for practical microphone applications! Here are a few ideas to get you started:
- Build a music visualizer! Here's a sample sketch for the music visualizer shown in the SparkFun Simple Sketches example.
- Record sounds and play them back! You'll also need a speaker, an amplifier transistor, and some pushbuttons (and some code. Here's an open-source mbed example).
- Make a sound-reactive EL Wire costume and replace the Sound Detector with the MEMS Microphone!
- Make a Bark Back Pet Monitor with a Raspberry Pi to record the sound levels in your home, upload the data MQTT, and trigger an audio player to when the volume reaches a threshold.

The Uncertain 7-Cube
The Uncertain 7-Cube is a non-committal, less-than-helpful, but also entirely honest fortune teller. Simply ask it a yes or no question, give it a nudge, and the 7-Cube will dutifully inform you that it doesn’t have all the facts and doesn’t feel comfortable making a guess.

Tsunami Super WAV Trigger Hookup Guide
This guide will get users started with the Qwiic Tsunami. We'll start by putting *.wav files and a configuration file on a microSD card, pop it into the Qwiic Tsunami, then trigger sounds across multiple outputs.
Happy building!
