I have an ultrasound sensor that when anything is more near than 7cm, a LED lights. I want that when the LED lights, the ESP8266 enter to a website. And I don't know so good how to connect all good, so if you indicate me I will be really thanks.
the ESP8266 enter to a website.
What does this mean? A client can make a GET request, and get a web page, if that is what the script that is invoked serves up. But, what is the Arduino going to do with a web page?
