前回の記事では3線タイプのサウンドモジュールの例を紹介しましたが、今回は4線タイプのサウンドモジュールの例を紹介します。3線タイプは音のあるなしのデジタル検出のみでしたが、4線タイプでは3線タイプ同様のデジタル検出に加えて、音圧の ...

音を検知するのに役に立つのがサウンドモジュールセンサです。基本は検出したかどうかのデジタル値（0 or 1）ですが、音の大きさや向きによってセンサの感じ取り方が変わりますから、工夫するとこんなデジタル値でもいろいろ使えます。 結線図 図1に ...

I have already made some devices using SeeedStudio’s Seeeduino Nano microcontroller boards and Grove Sensors. In this post I am going to show you how to make a simple sound activated electronic switch ...

To capture an instant on film or sensor with a camera, you usually need a fast shutter. But alternately a flash can be triggered with the scene in the dark and the shutter wide open. It’s this latter ...

An upgraded version of the classic Dancing LED project that uses a sound sensor to trigger LED patterns—making the LEDs dance in sync with claps, music, or other sounds. This project demonstrates how ...

This post describes the preliminary results of a small Hall-Sensor module. This is widely known as KY-024 module. The KY-024 sensor module I got from an online retailer is inexpensive, and the ...
