Error: compiling for node MCU1.0(ESP-12emodule)

Welcome to the forum

Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'

Use code tags (the < CODE/ > icon above the compose window) to make it easier to read and copy for examination

Please post your sketch, using code tags when you do, and a schematic of your project. A photo of a hand drawn circuit is good enough as long as it shows how the components are connected and powered and the type of Arduino board that you are using
