This post discusses how I integrated a regular microphone into an Arduino setup for some serious audio experiments. I used a prewired module which holds a MAX9814 single chip microphone amplifier with ...

When designing a microphone assembly the other day, I reached for an electret condenser microphone capsule without thinking. To be strictly accurate I ordered a pack of them, these small cylindrical ...

A cartridge-based console project that blends Arduino fundamentals, retro gaming nostalgia, and modern maker tools.

Before the invention of microelectromechanical system (MEMS) microphones, almost all microphones in cell phones and other electronics were a type of condenser microphone called the electret microphone ...

As our audio-reactive projects increase in sophistication, we may decide to replace a simple MEMS microphone plus amplifier with one that offers automatic gain control. This is a follow-on to my ...

This is an interesting one - how to make a smart doorbell using Arduino (basically, using a simple AI model to detect the doorbell ringing sound). The system uses the Renesas RA4M1-based Arduino UNO ...
