One of the common use cases for our Arduino Relay Controller is setting up a yard or staging ladder. An Arduino relay is often used to control power on tracks by steering or simply turning power on or ...

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 ...

Abstract: This paper aims to design a digital overcurrent relay with a characteristic of a standard inverse that can comply to the IEC standard 60255. The overcurrent relay which is used to protect ...

In the Arduino schematic, for some reason pin 2 on the NINA-W102 is labeled "GPIO34". At first I thought I was mistaken, and that pin 2 on the Arduino schematic really is GPIO34 on the NINA, but that ...
