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 ...

This Arduino library allows you to use Deneyap Relay with I2C peripheral. You can use this library in your projects with any Arduino compatible board with I2C peripheral.

Here is the circuit of an Arduino-based Panic Alarm! The wiring is very simple so that even a novice can construct this interesting circuit without any difficulty. Arduino is a family of ...
