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 ...

By using an Arduino Uno and a single-channel relay module, you can control high-voltage or high-power devices, such as lights, motors, and appliances, from your computer or mobile device. In this blog ...

This project uses GSM Module (SIM900) with Arduino to switch Relay state by SMS OR CALL. Step 1 (Connect SIM900 With Arduino) Use picture as a reference for connecting SIM900 to Arduino.

Upload Arduino source code (HomeAutomation.ino) to Arduino Uno. The source code can be downloaded by scanning the QR code given in Fig. 6. Next, pair Bluetooth module HC-05 with Bluetooth of your ...

A 26.000MHz crystal is used in the ESP-01/ESP-01S module. In order to use the ESP-01 Wi-Fi relay module, a programmer/programming adapter is required to program the ESP-01 module (see below). Also it ...

So, to address these problems we will make an inexpensive voice-controlled home automation system using easy to find components such as Arduino Nano, HC-05 Bluetooth module and relay driver board. The ...

I checked several Arduino projects and related libraries available online but was confused. Finally, I decided to do my first test with the help of a Windows 10 computer as the host. First, I ...
