## Arduino
- To configure the integration, simply provide the IP / hostname and port number of the Arduino device that is listening. The code below is an example of what should be running on the Arduino to receive requests from XSOAR.

#### Example Arduino Code

---

```c
#include <SPI.h>
#include <WiFi.h>
#include "arduino_secrets.h"

char ssid[] = SECRET_AP;          // your network SSID (name) - This is defined in the "arduino_secrets.h" file
char pass[] = SECRET_KEY;         // your network password  - This is defined in the "arduino_secrets.h" file
IPAddress myAddress;

/*
   An example of the "arduino.secrets.h" file would be

  #define SECRET_AP "myWiFiNetwork"
  #define SECRET_KEY "myWiFiPassword"

*/

int status = WL_IDLE_STATUS;
int port = 9090;                  // Default port number to listen on

WiFiServer server(port);

void setup() {
  Serial.begin(9600);             // Start a Serial connection
  //while(!Serial);               // Uncomment to wait until Serial connection is available
    
  Serial.print("Attempting to connect to SSID: ");
  Serial.println(ssid);
  status = WiFi.begin(ssid, pass);
  if ( status != WL_CONNECTED) {
    Serial.println("Couldn't get a wifi connection");
    while (true);
    // don't do anything else:
  }

  Serial.print("Connected to ");
  Serial.println(ssid);
  myAddress = WiFi.localIP();
  Serial.print("My IP is: ");
  Serial.println(myAddress);
  Serial.print("Starting listener on port ");

   * By default, this just sends the data back to the sender
