Usage Instructions

Connecting the Shield to an Arduino

  1. Align the WINC1500 shield pins with the headers on your Arduino board.
  2. Gently press down to ensure a firm connection without bending the pins.
  3. Verify that the shield is seated properly and there are no loose connections.

Software Setup

  1. Install the Adafruit WINC1500 library through the Arduino Library Manager.
  2. Include the library in your sketch by adding #include <WiFi101.h> at the beginning of your code.
  3. Initialize the WiFi module in your setup() function using WiFi.begin(ssid, pass).

Example Code

#include <SPI.h>
#include <WiFi101.h>

char ssid[] = "yourNetwork";     // your network SSID (name)
char pass[] = "secretPassword";  // your network password

void setup() {
  // Initialize serial communication for debugging
  Serial.begin(9600);
  while (!Serial) {
    ; // Wait for serial port to connect.
  }

  // Check for the presence of the shield
  if (WiFi.status() == WL_NO_SHIELD) {
    Serial.println("WiFi shield not present");
    // Don't continue if the shield is not present
    while (true);
  }

  // Attempt to connect to WiFi network
  while (WiFi.begin(ssid, pass) != WL_CONNECTED) {
    Serial.print("Attempting to connect to SSID: ");
    Serial.println(ssid);
    // Wait 10 seconds before retrying
    delay(10000);
  }

  Serial.println("Connected to wifi");
  printWiFiStatus();
}

void loop() {
  // Nothing here for now.
}

void printWiFiStatus() {
  // Print the SSID of the network you're attached to
  Serial.print("SSID: ");
  Serial.println(WiFi.SSID());

  // Print your board's IP address
  IPAddress ip = WiFi.localIP();
  Serial.print("IP Address: ");
  Serial.println(ip);

  // Print the received signal strength
  long rssi = WiFi.RSSI();
  Serial.print("Signal strength (RSSI):");
  Serial.print(rssi);
  Serial.println(" dBm");
}
