First project and I'm LOST!

My hardware is; Arduino Uno R3 with ESP8266 ESP-12E UART WIFI Shield
I am working on a MacBook Pro with the latest libraries loaded in my sketch folder.
I successfully created a local Blynk server.
Downloaded Blynk and created a project.
Connected to Blynk cloud server and got an authorization code.
I have the Arduino connected to the Mac via USB.

Now what??..
What do I do with the authorization code?

@Carloszeke welcome to the world of Blynk.

My advice to anyone starting off with Blynk is to forget about Arduino’s and local servers.

Use the ESP8266 (with USB port) and Blynk’s cloud server. It’s so much easier to learn this way.

This link shows you what you do with the authorisation code for the nasty shield system.
