Once you have the app installed. Take some time to plan out your control layout. Think of your goal and arrange the controls accordingly. In my case it was a bbq thermometer so I added two analog gauges.

Once you have your layout setup, configure the ports.

IMPORTANT: make note of the api key shown in the project settings in the blynk app.

 

Upload the Code

Install the blynk library into your arduino IDE like any other arduino library:

http://www.blynk.cc/getting-started/

And open the sketch that matches your hardware, in my case it was usb serial.

OR:

You can also just click the codebender link amd upload it directly from your browser!

IMPORTANT: paste that api key from earlier into the code where it says “api key”

 

See the Action!

Open your app and plug in a sensor/led to your arduino and watch the magic of blynk!

Note: if you are not using an ethernet shield then you have to keep the usb cable plugged into the computer
