Share My Creation ESP-01 IoT

The common way for IoT is to set the ESP8266 to server mode and connect to it from the WWW by entering your router static IP address in a browser. My internet provider don't have the option for static IP address. In this project the ESP is set to station mode and it sends several bytes of data to my website every 20 seconds. I can browse at the data from the internet by logging to a page in my website, read analog and digital input and also send a command to switch an output of the Arduino.
I use an Arduino Uno and ESP-01. The code controls the ESP using AT commands only. I used software serial so it's easier to upload the sketch. The code searches the response from the ESP for the command ON/OFF from the website.
I added a suggestion for a PHP script for the website. file a32.php is a blank file which a31.php writes the data to be recorded, page a33.php is for the user to read the data from the ESP and to send command to the Arduino.
In the code enter your SSID and PASSWORD of your router. Also change the name of my website to yours.
You can use my website to test your setup. http://moty22.co.uk/a33.php
