+# Code Samples
+
+To help you develop your sensor project you can make use of these code samples adapted from the samples provided by the Arduino IDE.
+
+## Connecting to the Internet
+
+One of the first tasks you will need to do is connect your ESP8266 to the internet by connecting to an access point.
+
+### Connecting in the Lab
+
+Unfortunately IoT devices such as NodeMCU (and Lego!) can't connect to the Main University WiFi and so we have set up a network for you to use.
+
+The `ECL-LEGO-ROBOTS` network is setup to allow internet on ports 1883 and 8883 and so you should connect to this and make sure you only use these ports to communicate.
+
+The code below will connect you to the 
+
+```cpp
+#include <ESP8266WiFi.h>
+#include <ESP8266WiFiMulti.h>
+
+ESP8266WiFiMulti WiFiMulti;
+
+void setup() {
+    Serial.begin(115200);
+    delay(10);
+
+    // We start by connecting to a WiFi network
+    WiFiMulti.addAP("ssid", "password");
+
+    Serial.println();
+    Serial.println();
+    Serial.print("Wait for WiFi... ");
+
+    while(WiFiMulti.run() != WL_CONNECTED) {
+        Serial.print(".");
+        delay(500);
+    }
+
+    Serial.println("");
+    Serial.println("WiFi connected");
+    Serial.println("IP address: ");
+    Serial.println(WiFi.localIP());
+
+    delay(500);
+}
+
+
+void loop() {
+    
+}
+```
+
+### Connecting at Home
+
+You should be able to connect to your home Wifi network without any issues by changing the ssid and password. If you are having problems check the _security settings_ and, if available, choose `WPA/WPA2-PSK (mixed mode)`. If you discover any more information that might be useful to others, edit this document and file a _merge request_.
+
+You should see the NodeMCU listed under _connected devices_ on your router admin page, with the name `ESP_XXXXXX` where XXXXXX is part of the Mac Address.
