after verifying and uploading this code in arduino ide for node mcu 8266, am getting an error
Invalid library found in C:\Users\Dell\Documents\Arduino\libraries\Blink: no headers files (.h) found in C:\Users\Dell\Documents\Arduino\libraries\Blink
Invalid library found in C:\Users\Dell\Documents\Arduino\libraries\sketch_oct09a: no headers files (.h) found in C:\Users\Dell\Documents\Arduino\libraries\sketch_oct09a

please suggest which library to add.
