Arduino Code 

Original Code from 
Rock solid esp8266 wifi mqtt, restful client for arduino
http://tuanpm.net/rock-solid-esp8266-wifi-mqtt-restful-client-for-arduino/

But,I've modified to control device with ThingSpeak.com

Arduino Code Download V0.2
www.softpowergroup.net/files/Arduino/thingspeak_Control2.zip


Code are need some edit.
Set your SSID Network and Passwoard.






Make your TalkBack Command to control deives.
and make your Channel for show your Data.
