In this article, we propose a circuit to monitor the temperature and control a relay over the local WiFi.

To use ESP8266 with Arduino, select the Board: "Arduino/Genuino Uno" and change it to "NodeMCU 1.0 (ESP-12E Module)" or other ESP8266 modules based on your hardware.

Here, we are using a 4 relay module because we will only control four appliances. If you want to automate a different number of appliances, you can use a different relay module. There are many relay ...

A single-channel relay is an electronic switch that can be controlled by a low-power electrical signal, such as the output from an Arduino microcontroller. By using an Arduino Uno and a single-channel ...

This IoT-based Apple Home Automation Project can control four home appliances. We are using Apple HomeKit, Siri app, and ESP8266 Wi-Fi module. A few months ago we were thinking of building a home ...

To connect your Arduino to the internet, there are two popular options. One option is to use an ESP8266 with Arduino and the second option is to connect an Ethernet module with Arduino. In this ...

By default, first relay module will be selected Below the selection, it displays the connection status If the relay module is found in the WiFi network, the text will change to "Connected" and it will ...

So, connect TX of ESP8266 to Pin 2 of Arduino and RX of ESP8266 to Pin 3. Since, ESP8266 cannot tolerate 5V, the TX of Arduino (pin 3) is first level shifted using two resistors (1 KΩ and 2.2 KΩ) and ...

Final connection after all the soldering and Arduino connection Connections All the pins described above will be connected as specified. Remember to give 3.3v voltage to ESP8266 it can’t withstand at ...
