Materials

  • Ameba x 1

 

Example


In this example, we connect Ameba to WiFi and use Ameba as server to send message to connected client.
First, open “File” -> “Examples” -> “AmebaWiFi” -> “WiFiWebServer”

Use server.available() to get a client that is connected to the server and has data available for reading.
https://www.arduino.cc/en/Reference/WiFiServerAvailable
Use client.connected to check whether or not the client is connected.
https://www.arduino.cc/en/Reference/WiFiClientConnected
Use client.println() to print data followed by a carriage return and newline.
https://www.arduino.cc/en/Reference/WiFiClientPrintln
Use client.print() to print data to the server that a client is connected to.
