The sketch will start immediately - you'll see the LED blinking. Hooray!

Connecting via WiFi

OK once you've got the LED blinking, lets go straight to the fun part, connecting to a webserver. Create a new sketch

with this code:

* Simple HTTP get webclient test

#include <ESP8266WiFi.h>

const char* ssid = "yourssid";

const char* password = "yourpassword";

const char* host = "wifitest.adafruit.com";

void setup() {

Serial.begin(115200);

delay(100);

// We start by connecting to a WiFi network

Serial.println();

Serial.print("Connecting to ");

Serial.println(ssid);

WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) {

delay(500);

Serial.print(".");

}

Serial.println("");

Serial.println("WiFi connected");

Serial.println("IP address: ");

Serial.println(WiFi.localIP());

Serial.print("Netmask: ");

Serial.println(WiFi.subnetMask());

Serial.print("Gateway: ");

Serial.println(WiFi.gatewayIP());

}

int value = 0;

void loop() {

delay(5000);

++value;

Serial.print("connecting to ");

Serial.println(host);

// Use WiFiClient class to create TCP connections

WiFiClient client;

const int httpPort = 80;

if (!client.connect(host, httpPort)) {
