  // Make sure your Serial Terminal app is closed before powering your device
  Serial.begin(9600);
  // Wait for a USB serial connection for up to 30 seconds
  waitFor(Serial.isConnected, 30000);

  Serial.println("connecting...");

  if (client.connect(server, 80))
  {
    Serial.println("connected");
    client.println("GET /search?q=unicorn HTTP/1.0");
    client.println("Host: www.google.com");
    client.println("Content-Length: 0");
    client.println();
  }
  else
  {
    Serial.println("connection failed");
  }
}

void loop()
{
  if (client.available())
  {
    char c = client.read();
    Serial.print(c);
  }

  if (!client.connected())
  {
    Serial.println();
    Serial.println("disconnecting.");
    client.stop();
    for(;;);
