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 ...

Throw some blinking LEDs on a project and it’s bound to make the front page of Hackaday. We do love builds of a more analog character, though, and this analog gauge stepper motor breakout board seems ...

The EEWeb Design Contest First Edition sponsored by Arduino and Altium is now open for submissions. This inaugural contest challenges hardware design enthusiasts from all over the world to develop an ...

Ask anybody whose spent time standing in front of a mill or lathe and they’ll tell you that some operations can get tedious. When you need to turn down a stainless rod by 1/4″ in 0.030″ increments, ...

I like this one - a super impressive Arduino-based barometer for measuring air pressure. There's something satisfying about the link with nature, a tangible connection with outside weather. In a ...
