Internet of Things (IoT) tizimi modelini yaratish. Internet of Things (IoT) uchun dastur yaratish

String readString; 
O'rnatish funksiyasi chiqish uchun LED pinini ishga tushiradi va Ethernet 
modulini berilgan parametrlar (Mac manzili, IP manzili, shlyuz, pastki tarmoq 
maskasi) bilan ishga tushiradi va nihoyat, server "server.begin()" funksiyasi 
tomonidan ishga tushiriladi.
int ledPin = 2;
void setup(){
pinMode(ledPin, OUTPUT); 
Ethernet.begin(mac, ip, gateway, subnet);

server.begin(); 
}
Loop funksiyasida biz mijoz ulanishini yaratamiz va kimdir tayinlangan 
IPmanzilga brauzer orqali kirishga urinayotganligini tekshiramiz.
void loop(){
 EthernetClient client = server.available();
if 
(client) {
while (client.connected()) {

if (client.available()) {
Agar ulangan bo'lsa, mijoz serverga qandaydir xabar yuborayotganligini 
tekshirishni davom eting.
char c = client.read();
Keyin HTTP javobini char bo'yicha o'qing va belgilarni foydalanuvchi 
tomonidan belgilangan readString o'zgaruvchisiga saqlang.
if (readString.length() < 100) {
 readString += c;
}
agar HTTP so'rovi tugagan bo'lsa - 0x0D Carriage Return \n ASCII

if (c == 0x0D) {
OK javobini olganimizdan so'ng biz veb-sahifani ko'rsatishni boshlaymiz va

Foydalanuvchi YOQISH LED giperhavolasini bosganda, u yana LEDni 
yoqadigan URL \?LEDON ga yo'naltiriladi.
client.println("

Yuqoridagi kodga o'xshab, bu foydalanuvchini "TURN OFF LED" URL 
manziliga yo'naltiradi.
