This project involves controlling a relay using a Light Dependent Resistor (LDR) and an Arduino. The system detects the ambient light intensity using the LDR sensor. Based on the detected light level, ...

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 ...

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 ...

The article is a tutorial on how to control 16 relay through Arduino microcontroller with Ethernet shield W5100.

Arduino Due and the Ethernet shield W5100 have the microcontroller, which has enough GPIO pins for the 16 channel relay , or 2x 8-channel relay. Since Due does not have everyone, the prepared source ...
