Arduino sketch for the Adafruit Feather Huzzah ESP8266 to notify an Adafruit Dashboard
/*
- This sketch sends a notice to an Adafruit IO Dashboard
- when someone arrives (presses a green button) or leaves (presses a red button) the Maker Space.
- Everyone at the Maker Space can view the Adafruit IO Dashboard to see if someone is currently present at the space.
- This uses:
- an Adafruit Feather Huzzah ESP8266 -- important to select this as the board in the Arduino IDE
- an Adafruit IO account to capture the data
- an Adafruit text feed to receive text-based notifications from the ESP8266
- an Adafruit dashboard to display the notifications
- 1 RGB LED, common anode
- 2 buttons, ideally with 1 red cover and 1 green cover */
