With everything setup correctly, upload the code! Once the code finishes transferring, open the serial monitor
and set the baud rate to 115200. You should see Hello, world! 's begin to fly by. You may also notice that when
the ESP32 boots up it prints out a long sequence of debug messages. These are emitted every time the chip
resets -- always at 115200 baud.

You should also see some blinking happening on the ESP32 Processor Board! Blink Blink Blink!

If the blue LED remains off, it's probably still sitting in the bootloader. After uploading a sketch, you may need
to tap the reset button to get your ESP32 MicroMod to run the sketch.
Arduino Example: WiFi
The ESP32 Arduino core includes a handful of WiFi examples, which demonstrate everything from scanning for
nearby networks to sending data to a client server. You can find the examples under the File > Examples > WiFi
menu.
Here's another example using the WiFi library, which demonstrates how to connect to a nearby WiFi network and
poll a remote domain (http://example.com/) as a client.
Please note: Make sure you are connecting to the 2.4GHz band on your wireless router; the ESP32 is not
compatible with 5GHz signals.
