/*This code assumes you have connected the RX pin of the ESP8266 module to pin 2 (ESP8266_RX) of the Arduino Uno and the TX pin of the ESP8266 module to pin 3 (ESP8266_TX) of the Arduino Uno. Also, replace "yourserver.com" with the address of your server.

On the server side, you would need to have a script or service listening for incoming HTTP requests and processing the data sent by the Arduino via the ESP8266 module.

Remember, this is a basic example, and you may need to adjust it based on your specific requirements and the ESP8266 module's configuration.*/
