Once that works, upload eiher of these sketches, with your SSID & network password:

Sketch Explanation

This sketch is not much different than the SSL test sketch.


In the pre-setup configuration, you can set up your SSID & password. Also, set what pin has the LED connected. Define the path you want to grab, change this to your favorite twitch streamer

// Define the WINC1500 board connections below.
// If you're following the Adafruit WINC1500 board
// guide you don't need to modify these:
#define WINC_CS   8
#define WINC_IRQ  7
#define WINC_RST  4
#define WINC_EN   2     // or, tie EN to VCC and comment this out

#define LED 13

// Setup the WINC1500 connection with the pins above and the default hardware SPI.

// Or just use hardware SPI (SCK/MOSI/MISO) and defaults, SS -> #10, INT -> #7, RST -> #5, EN -> 3-5V
//Adafruit_WINC1500 WiFi;

char ssid[] = "networkssid"; //  your network SSID (name)
char pass[] = "networkpass";    // your network password (use for WPA, or use as key for WEP)
int keyIndex = 0;            // your network key Index number (needed only for WEP)

int status = WL_IDLE_STATUS;
#define HOST "api.twitch.tv"
#define PATH "/kraken/streams/adafruit"
#define REFRESH 20  // seconds between refresh

Adafruit_WINC1500SSLClient client;


In setup we just check that the WiFi module is attached, and set the pin #13 LED to an output

void setup() {
#ifdef WINC_EN
  pinMode(WINC_EN, OUTPUT);
  digitalWrite(WINC_EN, HIGH);

  pinMode(LED, OUTPUT);
  //Initialize serial and wait for port to open:
  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only

  // check for the presence of the shield:
  if (WiFi.status() == WL_NO_SHIELD) {
    Serial.println("WiFi shield not present");
    // don't continue:
    while (true);


We start by checking if we are connected to the SSID, if not we connect

void loop() {
  // attempt to connect to Wifi network:
  if (WiFi.status() != WL_CONNECTED) {
    while (WiFi.status() != WL_CONNECTED) {
      Serial.print("Attempting to connect to SSID: ");
      // Connect to WPA/WPA2 network. Change this line if using open or WEP network:
      status = WiFi.begin(ssid, pass);
      // wait 10 seconds for connection:
      uint8_t timeout = 10;
      while (timeout && (WiFi.status() != WL_CONNECTED)) {
    Serial.println("Connected to wifi");

Then we SSL connect to twitch.tv and ask for the path from the setup section

  Serial.println("\nStarting connection to twitch...");
  // if you get a connection, report back via serial:
  if (client.connect(HOST, 443)) {
    Serial.println("connected to twitch api server");
    // Make a HTTP request:
    client.println("GET " PATH " HTTP/1.1");
    client.println("Host: " HOST);
    client.println("Connection: close");

We then use find to locate whether the magic string appears

  boolean isStreaming = false;
  while (client.connected()) {
    if (client.find("\"stream\":{\"_id\":")) {
      isStreaming = true;

if so, then isStreaming is set to true. Finally we print out the current status, wait a few seconds, and restart the loop

Serial.print("Streaming status: "); Serial.println(isStreaming);
  digitalWrite(LED, isStreaming);
  Serial.println("disconnecting from server.");
