This repository contains a code snippet for creating a simple web server using NodeMCU (ESP8266) to log and display messages received from a 433MHz receiver.

• NodeMCU board (ESP8266-based)
• Arduino IDE or compatible development environment
• ESP8266WiFi library
• ESP8266WebServer library
• RCSwitch library

1. Clone or download this repository.

2. Open the arduino-443mhz-web-ui.ino file in the Arduino IDE.

3. Install the required libraries:

   • ESP8266WiFi: Install via Arduino Library Manager.
   • ESP8266WebServer: Install via Arduino Library Manager.
   • RCSwitch: Download the library from https://github.com/sui77/rc-switch and install manually.

4. Connect your NodeMCU board to your computer.

5. Set the Wi-Fi credentials:

   • Update the ssid and password variables in the code with your desired SSID and password for the Wi-Fi hotspot (default 443 and adminadmin)

6. Upload the code to your NodeMCU board.

7. Open the Arduino IDE serial monitor to view the IP address assigned to the Wi-Fi hotspot.

8. Connect to the Wi-Fi hotspot using the provided SSID and password.

9. Open a web browser and enter the IP address displayed in the serial monitor.

10. The web page will display the received messages, including the decimal and binary representation of each value.

• If you want to change the pin for the 433MHz receiver, modify the receiverPin constant in the code. By default, it is set to D2 on the NodeMCU board.
