Hi, I installed esp8266 v 2.4.1 by using board manager. During time of compiling there showing the error that the functions are " not declared in this scope ". But there is no problem while I moved that function to top of "void setup()". I just started this please help.

Esp8266 2.4.1 update

If you want to write your code the 1st way, you need void Led(); at the top of the sketch.
