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.

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 ...

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 ...

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, ...

The 5V and GND pin of the RDM6300 module is connected to the 5V and GND pin of Arduino Nano while the TX pin of the module is connected to D6 of Nano. The RX pin is not required as we do not send data ...

Another pin you can use on the Nano to power it up is the 5V pin (located on Pin 27, close to the VIN pin at the end of the board). This pin mostly serves as a power output pin that supplies power ...

Both the Arduino Nano and Uno can be powered via their integrated USB connectors. This automatically supplies regulated 5V power to the board, allowing you to use any USB-supported power source ...
