Doggy door with Alexa (updated 1 of 2)

Here I shown you how did I assemble a hardware in conjunction with Arduino ESP32 Sketch to control the doggy door via Web server, and also added to the Alexa control command, so I can open and close the doggy door via voice command and Alexa App from anywhere. From Anywhere? how? in the house via multiple Echo units located in different rooms and when I am out of house I use my Iphone and Alexa app or Amazon music App to issue the voice command. With new updated version of Sketch I added some codes to enable user to enter number of turns within stepper motor shaft with quarter turn resolutions via web server, this number will be save on ESP32 EEPROM as well so power interruption does not erase or effect previously input data.
