What is Blynk?

Blynk is a platform with iOS and Android apps to control Arduino, Raspberry Pi and the likes over the Internet.
You can easily build graphic interfaces for all your projects by simply dragging and dropping widgets. If you need more information, please follow these links:

• Kickstarter campaign
• Blynk downloads, docs, tutorials
• Blynk community
• Facebook
• Twitter

Please find examples on how to use different types of connections (transports) and how to do make something great with Blynk. You can easily apply any type of board/connection to all examples.

Quickstart: Arduino + Ethernet shield

• Download the Blynk app (App Store, Google Play)
• Get the Auth Token from the app
• Import this library to Arduino IDE. Guide here
• In Arduino IDE, select File -> Examples -> Blynk -> BoardsAndShields -> Arduino_Ethernet
• Update Auth Token in the sketch and upload it to Arduino
• Connect your Arduino with Ethernet shield to the internet

Supported boards, WiFi, Serial, USB...

See examples with different connection types.

Full list of supported hardware is here.

Troubleshooting

To enable debug prints on default Serial, add on the top of your sketch (should be the first line ):

    #define BLYNK_DEBUG // Optional, this enables lots of prints
    #define BLYNK_PRINT Serial

And enable serial in setup():

    Serial.begin(9600);

WARNING : enabling debug mode will slowdown your hardware processing speed up to 10 times.
