Exchange any data between Blynk app and your hardware.

Virtual Pin is a concept invented by Blynk Inc. to provide exchange of any data between hardware and Blynk mobile app. 

Virtual pins are different than  Digital and Analog Input/Output (I/O) pins. They are physical pins on your microcontroller board where you connect sensors and actuators.

Blynk lets you control any hardware connected to Digital and Analog pins without having to write any additional code.

For example, if you need to turn On/Off LED connected to Digital pin, you don't have to write any code: 

1. Just use BlynkBlink code for your hardware. 
2. In the Blynk app - add Button Widget and set it to pin D8
3. That's it! No additional code is required. Simply press Play in the app.
