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 ...

Arduino today announces that the Arduino GSM Shield, developed in conjunction with Telefónica’s Physical Internet Laboratory, is now available to purchase. The GSM Shield adds a GPRS/GSM connection to ...

SIMカードは、既存の通信業者のものを利用可能です。 「DIY Cellphone」のシステムは、オープンソースハードウェアである Arduino から派生した「Arduino GSM シールド」のシステムを使って動作する仕組みになっています。

Microcontrollers like Arduino are designed to control small loads, such as LEDs or sensors, directly from their output pins. However, these pins can only supply a limited amount of current (typically ...

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 ...

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 ...

If you’ve spent much time tinkering with electronics, you’ve probably heard of [Seeedstudio] from their development boards, tools, and their PCB fabrication service. Their latest Kickstarter venture ...

This project implements a GSM-based home automation system using Arduino UNO. The system allows switching of home appliances using SMS commands.
