Dette eksempel tager udgangspunkt i et eksempel fundet ved esp8266learning.com<ref>[http://www.esp8266learning.com/wemos-webserver-example.php Eksempel på Webserver]</ref>.

Formålet er at reducere koden, så den viser det helt basale.

==Samlet kode==
<source lang="C">
#include <ESP8266WiFi.h>

const char* ssid = "ssid name";
const char* password = "ssid password";

WiFiServer server(80);

void setup() {
Serial.begin(115200);
delay(10);

// Connect to WiFi network
WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");

// Start the server
server.begin();

// Print the IP address
Serial.print("Use this URL : ");
Serial.print("http://");
Serial.print(WiFi.localIP());
Serial.println("/");
}

void loop() {
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}

// Wait until the client sends some data
Serial.println("new client");
while(!client.available()){
delay(1);
}

// Read the first line of the request
String request = client.readStringUntil('\r');
client.flush();

// Return the response
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println(""); // do not forget this one
client.println("<!DOCTYPE HTML>");
client.println("<html>");

client.println("<h1>Hello World</h1>");
client.println("</html>");

delay(1);
}
</source>
==Server Connection==
Som beskrevet i [[WeMOS Server Connection]] forbindes til Wifi og der sættes en server op. Det er primært i [[setup()]] det sker:
<source lang="C">
void setup() {
Serial.begin(115200);
delay(10);

// Connect to WiFi network
WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");

// Start the server
server.begin();

// Print the IP address
Serial.print("Use this URL : ");
Serial.print("http://");
Serial.print(WiFi.localIP());
Serial.println("/");
}
</source>

==Connection response==
Der registreres i [[loop()]] om der kommer en henvendelse, og hvis der gør, så sendes en simpel respons, der består af "Hello World" i et H1-tag:
<source lang="C">
void loop() {
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}

// Wait until the client sends some data
Serial.println("new client");
while(!client.available()){
delay(1);
}

// Read the first line of the request
String request = client.readStringUntil('\r');
client.flush();

// Return the response
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println(""); // do not forget this one
client.println("<!DOCTYPE HTML>");
client.println("<html>");

client.println("<h1>Hello World</h1>");
client.println("</html>");

delay(1);
}
</source>
