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 ...

Download "sms_call_gate.ino" Sketch from the repository and Upload it to Arduino. NOTE : Make sure to replace your number in code at line number 71. The number must be in international format. After ...

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 project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

The article is a tutorial on how to control 16 relay through Arduino microcontroller with Ethernet shield W5100. Hello, I'm going to share again with another project that helps many of you to solve ...
