Procedure
In this example, we connect Ameba to WiFi and use Ameba as server, the user can control the LED on/off through a webpage.
First, connect Ameba with the LED.
In a LED, the longer pin is the positive pole, and the shorter pin is the negative pole. So, we connect the shorter pin to GND and connect the longer pin to D13. Additionally, to avoid the electric current exceeds the tolerance of the LED and causes damage, we connect a resistance on the positive pole.

Note:
For
RTL8720DN(BW16) board, you may consider to re-define “LED_PIN” macro to 10 for built-in green LED, or 11 for blue built-in LED, or 12 for red built-in LED to avoid using extra components.
Then open “File” -> “Examples” -> “WiFi” -> “SimpleWebServerWiFi”
In the sample code, modify the highlighted snippet to corresponding information.
Upload the code and press the reset button on Ameba. When the connection is established, you will see the message “To see this page in action, open a browser to //xxx.xxx.xxx.xxx” in the Arduino IDE, as shown in the figure:
Next, open the browser of a computer or a cell phone under the same WiFi domain, enter the address in the message.
