Arduino based Automatic Plant Irrigation System with Message Alert Never forget to water your plants again with this intelligent irrigation system. Using an Arduino microcontroller, moisture sensors, ...

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 ...

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 ...

If the card gets recognized, the Arduino sends a signal to the relay to unlock the solenoid door lock for 10 seconds, Later, it locks the door automatically. To make it more user-friendly, I decided ...

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 ...

Thanks to Bootstrap, the relay in a column can also be controlled via a smartphone or other device, and it can be customized. Source codes for Arduino can also be used for an Ethernet shield / W5500 ...

Arduino Due and the Ethernet shield W5100 have the microcontroller, which has enough GPIO pins for the 16 channel relay , or 2x 8-channel relay. Since Due does not have everyone, the prepared source ...
