Boa tarde pessoal, desculpe-me caso esteja postando no lugar incorreto.
estou com uma duvida, sou novato no arduino, por isso peço a ajuda de voces, tenho o codigo abaixo no arduino, quando acesso pelo browser, o browser fica o tempo todo carregando até a pagina expirar, o que pode ser. Atecipadamente, agradeço.
