Ciao a tutti,
devo fare un web server che riceve dati da un tmp36 per temperatura e visualizza una pagina html se interrogato da web, il mio problema è che sono alle prime armi e provando a capire i codici sul sito officiali cado in errori che non riesco a risolvere e capire.
Il codice che mi riferisco è questo:
/*
Web Server
A simple web server that shows the value of the analog input pins.
using an Arduino Wiznet Ethernet shield.
Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13
* Analog inputs attached to pins A0 through A5 (optional)

Questo report potrebbe essere più ricco
di informazioni con
"Mostra un output dettagliato durante la compilazione"
abilitato in "File > Impostazioni"
come posso risolverli?
grazie in anticipo
