Ola, tudo bem?
Alguem pode me ajudar?
Adaptei esse sketch em um ESP32, tem conecção WI-FI direto com reset pino 4.
Cotação STOCK EUA
CRIPITO
B3

Porem a B3 parou de funcionar.
Com a API do nosso amigo
@felipemarinho97 com o link: https://felipemarinho.vercel.app/api/b3/prices/
Vou colocar o Sketch para analizarem.
Agradeço a atenção.
Fico no aguardo.

Pelo que entendi, teria como colocar um comando para que o site achei que é Android ou windows, pois neste caso acho que funciona , pois ao link abre e diz verificar o sistema operacional.
