ESP8266 ESP12 + Arduino IDE + Blynk + WiFi + LED

I found Blynk somewhere in my Twitter feeds and it catches my curiosity. :D

The setup is quite simple:
All I need was an ESP8266 module, LED, and a WiFi connection.
I use a USB-TTL adapter to program the ESP12, Arduino Uno as my 3.3V power source and a power bank as my 5V source.

All of the wiring is on the github link above. For my case, i use GPIO14 to control the LED.

Arduino IDE was being used to upload the Blynk firmware.
My module runs at 115200 baud rate.
