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 ...

Application control is “via real-time dashboards combined with the Arduino Cloud or third-party services”. Software development is typically Arduino, via Arduino sketches, tutorials and libraries, and ...

Designed in partnership with Finder – an industrial and building automation device manufacturer – it’s aimed at professional developers wanting to take advantage of the wider Arduino ecosystem. It’s ...

After wiring up each outlet so it can be controlled independently, he set out designing a four port relay board. This was a pretty simple build – four 10 Amp relays and a few terminal blocks.

The new Arduino Portenta H7 Lite development board is available to purchase priced at $72 and complies with the Arduino MKR form factor, but is enhanced with the Portenta family’s 80-pin, high ...

As the valves use 24V and the motor 12V, standard N-Mosfets and power relays are used for voltage conversion. The remote controller [Gilard] used is actually 20 years old, so the output signal of ...
