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 ...

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 ...

Patrick Thomas Mitchell has been once again been creating awesome add-ons for your Arduino projects and has this month launched a new Kickstarter campaign for his Arduino speech recognition and relay ...

The official Arduino IDE is a dour piece of software designed for uploading code to the ubiquitous and super-cool micro controller. It is a standalone, non-networked app that isn’t very pretty to look ...

This Arduino module takes past circuits and codes, and applies them to a new program called Snap4Arduino. Snap4Arduino allows us to program an Arduino board in an environment similar to Scratch, which ...

Never get between a man and his salami. [Mike] needed a way to control temperature, humidity and airflow with his meat curing setup. Of course he could modify a refrigerator and humidifier to be ...
