“You can’t put new wine in old bottles” – so the saying goes. But you would if you’re a hacker stuck with a radio built in 2005, which looked like it was put together using technology from 1975.

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 ...

The world of littleBits (the “not-a-toy” toy that I reaaaally wish existed when I was younger) just got a little bit bigger: it can now play friendly with Arduino. If you’re not familiar with ...

Discover how the Arduino Opta Pro can be leveraged beyond its industrial roots for smart home and DIY automation. In my article, I share hands‑on insights, practical code examples, and hardware ...
