TROCAR IP VIA WEB
Boa noite, meu nome é João Pedro e preciso de ajuda com um projeto, um amigo me passou um condigo um pouco complicado mas que funciona, o mesmo trata-se de trocar o ip via web, nesse código o ip é armazenado na eeprom e o arduino sempre lé a eeprom quando inicia, até ai tudo bem, o que eu quero é implementar nesse código é o acionamento de 5 cargas(tipo receber comandos de uma pagina e acionar relés), mas não consegui, abaixo segue o código, se alguém puder ajudar eu agradeço.
/*
This an Embedded Network Setup Webpage.
When you use the default ip-address in a webbrowser
You'll see a simple text like:
IT WORKS: go to "default-IP"/setup
This default webpage can be replaced by your own
if you go to "default-IP"/setup in a webbrowser
You'll get a network setup page.
It will pressent you the current setup filled out
When you press SUBMIT, the new values will be
saved to EEPROM (and thus still available on RESET).
Now you'll have to RESET your Arduino your self
and it will be available at your submitted IP.
You will need the arduino ethernet shield
and some libraries
