這是一個物聯網排隊掛號機，當初在參加黑客松之前想出來的
起因是和財政部長在逛夜市的時候，想吃某一個排隊名店
But... 人多到漫出來啦!
所以當時就在想大家都有手機，等號碼快到的時候就推撥到手機叫你來領食物就好啦~
當時是用arduino yun做的，現在可以改為ESP8266
這樣加電源與Cloud的成本應該不用5USD，是不是比紙印掛號機的便宜呀?
要不要叫醫院也跟進一下??
好了!廢話不多說，而且這支code應該有半年了，我都快看不懂了
以下是arduino yun的code

Android的code方面，下載parse的tutorial的code來修改就行了
之前寫的很亂，最近有時間再整理一下，暫時不放上來丟人現眼了
