Boa tarde galera...estou com uma dúvida com o estado de um led no meu arduino duemilanove + etherneth shield wiznet5100.
Eu consigo ligar e desligar o LED, mas se eu deixar o LED LIGADO e fechar o browser, quando eu abro o browser denovo, o LED apaga.
Alguém sabe me dizer como faço para deixar o LED em seu ultimo estado?
Obrigado.
vc esta bem confuso, eu fiz o código do post que vc apagou.
pra evitar de ler o estado do pino é mais facil fazer uma variavel de controle no caso aqui LEDON e FANON .
Eu não tenho como testar aqui apenas fiz o codigo e teste ai.

byte sampledata=50;
int ledPin = 4;
int fanPin = 5;
String readString = String(30);
boolean LEDON = false;
boolean FANON = false;
void setup(){
Ethernet.begin(mac, ip, gateway, subnet);
pinMode(ledPin, OUTPUT);
pinMode(fanPin, OUTPUT);
Serial.begin(9600);
}
void loop(){
// Cria uma conexao cliente
Client client = server.available();
if (client) {
while (client.connected()) {
if (client.available()) {
char c = client.read();
if (readString.length() < 30)
{
readString += c;
}
Serial.print(c);
if (c == '\n') {
if(readString.indexOf("L=1")>=0){
digitalWrite(ledPin, HIGH);
LEDON = true;
}
else if(readString.indexOf("L=0")>=0){
digitalWrite(ledPin, LOW);
LEDON = false;
}

client.println("<h2>Luz do Quintal</h2>");
client.print("<a href='L=1'>Ligar</a> | <a href='L=0'> Desligar </a> | Status :");
if(LEDON){

client.println("</body></html>");

Então Rafael,
você viu o ultimo codigo, mas se liga nesse:
Adicionei 1 termistor para medir a temperatura... TEMPERATURA OK(funcionou direitinho).
Porém, quando eu marco o checkbox e aplico a LUZ APAGA. Quando eu deixo desmarcada e aplico, a luz acende. Queria que fosse ao contrario.

esse esquema de form fica bonito mas só ocupa memória... se eu fosse vc deixa html puro.
vc tem q inverter a parte que lê
if(readString.indexOf("L=1") >=0)
{
//led has to be turned ON
digitalWrite(ledPin, LOW); // set the LED off
LEDON = false;
}else if(readString.indexOf("L=0") >=0){
digitalWrite(ledPin, HIGH); // set the LED on
LEDON = true;
}
Consegui acionar uma ventoinha depois que a temperatura atinge mais que 33 Graus Celcius.
Porém, coloquei o esquema de leitura LEDON da forma que você me passou e fica dando problema.
Eu quero acionar o LED da seguinte forma:
seleciono o checkbox, aplico, o LED liga, e o status fica ON.
se eu deixar o checkbox desmarcado e aplicar, o LED desliga, e o status fica OFF.
O código que postarei aqui em baixo está funcionando, porém está com as partes de LEDON, LOW, HIGH todo invertido.
Fora que mesmo se eu tiver ligado o LED, se eu fechar o browser e abrir novamente com o IP do ethernet shield, o LED apaga, sendo que eu queria que ele mantesse o estado que eu tinha deixado.
