Projeto arduino

R4malho · 21 de julho de 2016

Estou fazendo um pequeno projeto com arduino uno para liagr 8 dispositivos.

tudo funciona a questao e seguinte. quando acaba a energia os reles voltam todos ligados, eu quero que permanecem na mesma posição. segue parte do sketch.

tudo funciona beleza, ja fiz o app. com o app inventor 2 e ta uma beleza. so esse detalhe que esta difícil.

#include <SPI.h>
#include <String.h>
#include <Ethernet.h>

byte mac[] = { 0x00, 0xAA, 0xBB, 0xCC, 0xDE, 0x02 };
byte ip[] = { 192, 168, 4, 254 }
EthernetServer server(80); //Selecionar porta de saída (na video aula, foi utilizada 8090)

int led1 = 2;
int led2 = 3;
int led3 = 4;
int led4 = 5;
int led5 = 6;
int led6 = 7;
int led7 = 8;
int led8 = 9;
String readString = String(30);

String statusLed;

void setup() {
Ethernet.begin(mac, ip);
pinMode(led1, OUTPUT);
pinMode(led2, OUTPUT);
pinMode(led3, OUTPUT);
pinMode(led4, OUTPUT);
pinMode(led5, OUTPUT);
pinMode(led6, OUTPUT);
pinMode(led7, OUTPUT);
pinMode(led8, OUTPUT);
}
void loop() {

EthernetClient client = server.available();

if(client)
{
while(client.connected())
{
if(client.available())
{
char c = client.read();

if(readString.length() < 30) {
readString += (c);

}

if(c == '\n')
{

if(readString.indexOf("led1") >= 0) {
digitalWrite(led1,!digitalRead(led1));
}

if(readString.indexOf("led2") >= 0) {
digitalWrite(led2,!digitalRead(led2));
}

if(readString.indexOf("led3") >= 0) {
digitalWrite(led3,!digitalRead(led3));
}

if(readString.indexOf("led4") >= 0) {
digitalWrite(led4,!digitalRead(led4));
}

if(readString.indexOf("led5") >= 0) {
digitalWrite(led5,!digitalRead(led5));
}

if(readString.indexOf("led6") >= 0) {
digitalWrite(led6,!digitalRead(led6));
}

if(readString.indexOf("led7") >= 0) {
