ayuda con ethernet...

alguien me podria ayudar con el siguiente conmando? necesito agregar mas canales y un canal que trabaje como boton de reset…
desde ya agradesco sus comentarios…

#include <SPI.h>

byte mac = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; // mac address
byte ip = { 10, 0, 1, 17 }; // direccion IP fija en LAN
byte gateway = { 192, 168, 1, 1 }; // internet access via router
byte subnet = { 255, 255, 255, 0 }; //subnet mask
EthernetServer server(80); //server port
String readString;

pinMode(6, OUTPUT);

Ethernet.begin(mac, ip, gateway, subnet);
server.begin();

Serial.begin(9600);
Serial.println(“server LED test 1.0 ---- FILENAME = LED2.ino “); // so I can keep track
}
void loop(){
// Create a client connection
EthernetClient client = server.available();
if (client) {
while (client.connected()) {
if (client.available()) {
char c = client.read();
//read char by char HTTP request

//store characters to string
readString += c;
//Serial.print(c);
}
//if HTTP request has ended
if (c == ‘\n’) {
