The Arduino Nano, when paired with a relay module, allows control of high-power devices, enabling applications like home automation, industrial control, and robotics in various electronic projects.

The relay module will need 5V from Arduino to power up and will get input from four different digital pins of the Arduino. Now let’s connect the relay module to your home appliance. Take the positive ...

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 after turning on and off the appliances the receiver ...

As Arduino Nano board (Board2) cannot provide sufficient current to drive a relay, a 5V DC power adaptor is used for powering the relay module/board (RM1). To use 5V DC power adaptor with the circuit, ...

I have already made some devices using SeeedStudio’s Seeeduino Nano microcontroller boards and Grove Sensors. In this post I am going to show you how to make a simple sound activated electronic switch ...

Here using ATMEGA 4809 Arduino nano board and Capacitive Soil Moisture Sensor V2, I am trying to make an Automatic drip-irrigation system. Below is my code which is being used in the project. /* code ...
