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 ...

In this tutorial we will learn how simple it is to use Arduino 4 channel Relay Shield to control a 12V light bulb. In this tutorial we will learn how simple it is to use Arduino 4 channel Relay Shield ...

In this Lora project, I have shown how to make the LoRa Arduino ESP8266 control relay using the RYLR896 LoRa module with real-time feedback. So if you follow all the steps, you can easily make this ...

IN - This pin is also called the control pin because it is used to control the output of the relay. COM - is connected to the device you intend to connect. NC - terminal is connected to the COM ...

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 ...

Arduino program to handle relays and control them using switches with support for double-click and long-press. Integration with home automation systems is possible through MySensors integration over ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.
