Note for POLYUCS Edison Traffic Light

Download package: Source Code for arduino (Currently hard coded)
Makes use of FreeWiFi via POLYU (with a workaround)
Makes use of mqtt.eclipse.org
Announce topic: POLYUCS/esp8266/shared/pub (will have start msg and ping msg)
Config topic: POLYUCS/esp8266/devices/ESP8266Client-bcddc22df583/pub
- If switch device should then be : POLYUCS/esp8266/devices/<device-id>/pub
Worked on top of Clifford Choy's implementation
Commands and example:
- Set sequence timer, in ms, d[green, greenblink, yellow, red]:
  {
  "c": "setTime",
  "d": [5000,5000,5000,5000]
  }
- Set blink on off time, in ms, d[ontime, offtime]:
  {
  "c": "setBlink",
  "d": [500,200]
  }
- Set brightness, d:0..255
  {
  "c": "setBrt",
  "d": 128
  }
- Reboot, d:<a number hardcoded>
  {
  "c": "reboot",
  "d": 1234
  }
To change Defaults (Starting from Line405):
int brt = 255;
const unsigned long max_seq_time[] = {120000, 60000, 60000, 120000}; // for now not allowing more than 2 minutes
unsigned long seq_time[] = {20000, 5000, 4000, 25000}; // default green, blink, yellow, red
unsigned long blink_time[] = {400, 200};
