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 ...

I am building a 4-channel touchless switchboard. Arduino Uno, as the heart of the project, surrounded by four ultrasonic sound sensors, offers a simple, low-cost, and novel solution. The switches can ...
