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 ...

IN - This pin is also called the control pin because it is used to control the output of the relay. COM - is connected to the device you intend to connect. NC - terminal is connected to the COM ...

The concept of automation is getting popularity among people these days and many of them control their lighting, climate, etc remotely at their homes. Several microcontrollers or microprocessors can ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi with an ESP8266 ESP-01 module. With ...

An Arduino nano and relay module with 4 relays (see picture above) was used to simulate and replace the guitar 3-step switch. The project for Arduino is in PlatformIoClamp15. Node-red was used to ...

This project contains Arduino code for an ESP32 microcontroller to control a relay module, which in turn controls lights, to create a variety of blinking patterns. The code is designed to demonstrate ...
