Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I ...

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 ...

It’s not the first time we’ve seen a relay ... it with an Arduino Uno. It even looks like there might be enough space inside the box for a small wireless setup — maybe using a Trinket ...

In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

Cook At this point, your Arduino has the ability to sense ... You can just leave the power relay on top of the enclosure, ready to use with your fan or whatever appliance you’re looking to ...

Wouldn’t it be great is you could also use the ’16u2 on the Uno or Mega for some additional functionality to your Arduino sketch? That’s now a reality. [Nico] has been working on the ...
