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 ...

Scratch Arduino is Scratch 3.0 with Arduino and Arduino Robot Extensions. Arduino programming hasn't been easy, but using Scratch to program Arduino, it is more fun and simple than ever before!

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 ...

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 ...

Love Arduino but hate the GUI? Try arduino-cli. In this article, I explore a new tool released by the Arduino team that can free you from the existing Java-based Arduino graphical user interface. This ...
