cluck

This is:

1. a sketch for the Sparkfun Thing (ESP8266 board) that posts the state of a door (when it changes) to <data.sparkfun.com>
2. a webpage that reads the data from <data.sparkfun.com> 1x/second and updates the page text/color when it's changed.

Arduino sketch

1. Wake up from sleep
2. Read last state from EEPROM
3. Read new state from door sensor
4. If they are different:
5. flash onboard LED 1x
6. connect WIFI
7. post new state to data.sparkfun.com
8. flash onboard LED 2x
9. disconnect WIFI
10. go to sleep for specified # of seconds
11. GOTO 1

Webpage

1. read new status from data.sparkfun.com 1x/second
2. If it's different, update page

Don't forget!

• connect DTR to XPD to utilize deepSleep. If you do not, your thing will not wake up from sleep 'til it's manually reset
• on wakeup, sketch starts from the top so state can only be preserved across sleep by writing to EEPROM before sleep & reading from it after
