Simple walking direction sensor. Designed to send MQTT messages back to HA.

You will need to define a file secret.h that contains definitions for the following.

AIO_SERVER AIO_USERNAME AIO_KEY AIIO_SERVERPORT WLAN_SSID WLAN_PASS DIRECTION_FEED

The key and username may or maynot be important for your broker but they are required to use the Adafruit MQTT library
