I love to read through project suggestions and examples for the Arduino and ... First we learn the basics of using the Arduino Ethernet shield to connect your Arduino to a network.

This is an easy tutorial ... Arduino writes this value to the CONTROL pin, resulting in a variable voltage that is dependent on the pontetiometer value (its voltage on the adjustable pin, in this case ...

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 ...

The problem with using it along with Arduino-based gadgets is that you then need to use something like an Ethernet shield to provide the network connection. [Liam Lacey] decided to use Processing ...
