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 ...

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 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 ...

The use of Radio Frequency IDentification (RFID) technologies is growing. Many different applications are implemented in various sectors, and used for very different purposes. RFID enables wireless ...
