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 ...

This project demonstrates how to interface a relay module with an Arduino to control high-voltage appliances safely. The setup involves using a relay as a switch, allowing the Arduino to control ...

The article is a tutorial on how to control 16 relay through Arduino microcontroller with Ethernet shield W5100. Hello, I'm going to share again with another project that helps many of you to solve ...

A push button is connected to the ESP32 microcontroller. When its state changes, it will trigger an MQTT publish which will toggle the light controlled by a Shelly plus 1 relay. Keep in mind that you ...

You can read the state of a button using Arduino and a few lines of code. The actual state is shown in the Serial Monitor window as 0 or 1, 0 meaning the button is not pressed and 1 that the button is ...
