Receiver Lora Circuit Using Arduino In the receiver LoRa circuit, I have used NodeMCU as the microcontroller. In the circuit, I have also made a voltage divider using 4.7k and 10k resistors to drop ...

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 ...

This project demonstrates how to interface a relay module with an Arduino to control high-voltage appliances safely. The setup involves using a relay as a switch, allowing the Arduino to control ...
