+/* Adafruit IO Example Using WiFiManager
+ *
+ * This is a simple Adafruit feed subscribe example that uses
+ * WiFiManager to handle setup of WiFi credentials and connecting
+ * to the network instead of defining the WiFI SSID and password
+ * explicitly in the code.
+ *
+ * To use this example, add your Adafruit IO Username and Key
+ * and setup a feed called "myfeed".  When you manually add data
+ * to the feed on io.adafruit.com, you'll see that data written to
+ * the serial output.
+ *
