Hi i found it if the board is esp8266 need to change the const int output = 2; to
const int output = 5; as gpio 5 is d1 for esp8266

Hi.
In VS Code, all function definitions should show up before the setup() and it matters the order in which they appear (contrary to the arduino IDE).
Move the String outputState(){
if(digitalRead(output)){
return “checked”;
}
else {
return “”;
}
return “”;
}

To a place before the processor() function.

Sara

Then i went for this one, i copy pasted the raw code and when I try to upload
I get this :
