Code to control via network (via UDP protocol) a relay connected to an Arduino Uno, which mounts an ethernet shield. Here you can find the code and the connection scheme. **I tested the code with an ...

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 ...

Mini Project: Light-Dependent Relay Control using Arduino. This project involves controlling a relay using a Light Dependent Resistor (LDR) and an Arduino. The system detects the ambient light ...
