D1' was not declared in this scope; did you mean 'y1'?

Несмотря на то, что я упоминаю все в начале, тогда тоже m выходит за рамки ошибки. Ссылка на код :- https://noisycarlos.com/project/how-to-turn-your-computer-on-and-off-remotely/ Я не знаю, что здесь происходит. Я использую модуль ESP8266. Пожалуйста, помогите.
