Garage Door Opener With ESP8266 Wireless Web Server

// This Garage Door Opener script has a main and a tab named "server"
//credits to Arduino Forum member "nolasca" https://forum.arduino.cc/t/garage-door-opener-with-esp8266-web-server/1154364/41
//and Rui Santos ESP8266 Garage door opener 2 relays - programming //https://www.codemacs.com/iaot/applications/esp8266-//garage-door-opener.4002131.htm
// I edited this script to give a 12 second delay when the buttons are pressed and also to give a proper message statement on the buttons, when the web buttons are pressed, to give the user the Garage Door Status, and progress when the garage door is open and when the garage door is closed. It gives 12 seconds for the garage door to open and 12 seconds for the garage door to close.
