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 ...

Connect relays to digital output pins on whatever Arduino via appropriate isolation circuitry, starting at some pin (default 5), sequentially Set the start pin and number of relays at the top of the ...

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.

Energy is preserved by using this smart lighting system. The experimental results of this system have shown that 50% energy is conserved. But the difficulty is Raspberry Pi is more expensive than ...

Here, pin D12 of Arduino is used to drive a standard 5mm LED, and D13 is used to drive an Electro-Magnetic Relay through a transistor-based relay driver. Everytime the tag values match, D13 goes high ...

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 ...
