Switch on a lamp anywhere over the internet using website

Please watch this video for more detail about how to set up the website.

This project is about how to switch on/off a lamp over the internet through personal website even you are not in your home LAN(Local Area Network). You can access the website anywhere around the world using any web browser which installed in any devices like personal computer, notebook, smartphone or something else. In this simple project, I just create a simple website with button to switch on or off the lamp. For more security you can create on your own a log in page before the switch on/off page for your website to make it safe.

*NOTE :

Please make voltage divider between Arduino TX and ESP8266 ESP-01 RX.

*NOTE :

• Please change SSID Name & Password to your WIFI SSID Name & Password. ESP8266 will use your WIFI with internet connection to retrieve status of the lamp from your website. The website will store 0 for OFF and 1 for ON.

• Please change switchonthelamp.atwebpages.com to your website URL. You can watch my video for tutorial how to create free website using free web hosting like 000webhost or webfreehosting.net.

• Before upload this sketch, please remove RX and TX connection on arduino board. After upload done, you can connect it back.

SETUP WEBSITE (Please watch my video for more detail):

• Sign Up for new account on webfreehosting.net (You can use other free webhosting service).

• Sign In on webfreehosting.net.

• Set up free domain name.

• Set up database.

• Set up all three.php file (index.php, control.php & update.php).
