433 MHz with arduino yun


Untitled file

 Control light or any other applicace from Yeelink, Wechat,Temboo/ThingSpeak/DeviceHub of IFTTT by using arduino yun
 This sketch connects an 415 MHz to control light using the Yeelink (iOS,Andriod app and web), wechat, IFTTT(twitter), Blynk and IFTTTDo Button(DeviceHub)
 // Project Tutital :
 Version change log
 V1.0 created 11 May, 2015 to support Yeelink
 V1.1 update  12 May, 2015 to support wechat(weline)微信号:ECEFan
 V1.2 update  13 May, 2015 to support Temboo with twitter to read a tweet trigger by IFTTT when we push a DO button. 
 V1.3 update  14 May, 2015 to support ThingSpeak's App "Tweet Control" to read a tweet trigger by IFTTT when we push a DO button. 
 V1.4 update   3 June, 2015 to support 443 MHz RF module
 V1.5 update  11 June, 2015 to use Arduino Yun Bridge to connect this project to Blynk.
 V1.6 update  20 August, 2015 to support IFTTT DO Button on ios and android device by using api
