| This section tests the first basic task, compiling using the Arduino IDE software. I. Software Configuration 1.1 Adding Development Board Library Files <https://github.com/WIZnet-ArduinoEthernet/arduino-pico/releases/download/global/package_rp2040-ethernet_index.json> ![](https://maker.wiznet.io/upload/ckeditor5/206447427%5F1764933501%2Ejpg) 1.2 Installing Development Board Library Files ![](https://maker.wiznet.io/upload/ckeditor5/206447427%5F1764933513%2Ejpg) 1.3 Downloading the Software Package <https://github.com/WIZnet-ArduinoEthernet/arduino-pico/releases/download/global/package_rp2040-ethernet_index.json> ![](https://maker.wiznet.io/upload/ckeditor5/206447427%5F1764933532%2Ejpg) 1.4 Adding Libraries Manually add the library files by copying the downloaded files to the following folder. ![](https://maker.wiznet.io/upload/ckeditor5/206447427%5F1764933544%2Ejpg) II.

 }
 else
 {
   sprintf(buffer, "Echo request failed; %d", echoReply.status);
 }
 Serial.println(buffer);
 digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)
 delay(100);                      // wait for a second
