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 ...

This project is a sound-controlled LED system built using a microphone sound sensor module and an Arduino. The system detects clap sounds and changes LED states based on the number of detected sound ...

今日は、DTMF信号解析装置を紹介します。この装置は、M8870Aモジュール、Arduino、1602ALCDモジュールを使用して、 DTMF信号のシーケンス、トーンの遅延を表示するものです。以下では、装置の構成、動作の様子、そして技術的な詳細を順を追って解説します。

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...
