Arduinoとリレーを組み合わせて使用することで、Arduinoのデジタル出力を使って高電圧や大電流を扱う機器をコントロールできます。リレーは基本的に電気的に操作されるスイッチで、小さな電流で大きな負荷をオン・オフすることができます。これは特に家庭用電器やモーターなど、Arduinoの出力 ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

三馬力は、Arduinoのためのサンプルプログラム集「Arduino Sample Programs」を2018年8月26日発刊する。 同書は、Arduinoプログラミングを学習し始めてさらにステップアップしたい人、アイデアはあるが実際にどのようにArduinoを使って良いのかが分からない人向けの ...

This is a DIY Arduino-based overcurrent relay project that emulates Inverse Definite Minimum Time (IDMT) protection using an Arduino Nano and ACS712 current sensor. Instead of traditional ...

This repository contains an Arduino-based RFID cabinet door lock designed for industrial tool cabinets, lockers, and kiosk-controlled storage systems. The system reads RFID cards/tags, authorizes ...

Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...

This project implements a reliable and flexible cyclic timer system using an Arduino and a DS3231 real-time clock (RTC). It is designed for applications requiring precise periodic control with ...

Patrick Thomas Mitchell has been once again been creating awesome add-ons for your Arduino projects and has this month launched a new Kickstarter campaign for his Arduino speech recognition and relay ...
