Basic ESP-8266 Web Server Controlling Two LEDs
Posted: Thu Feb 18, 2016 12:07 amI found this information at http://randomnerdtutorials.com/esp8266- ... duino-ide/ and the sketch would not compile. I contacted Rui Santos and he said he had posted an older version of the sketch and he has since updated it. This sketch below is my updated version of his original old non-compiling sketch. I'm not associated with randomnerdstutorial.com in any way.
