# Void Loop()

The void loop() function is the part of the code that executes continuously. Over and over again. 

For this application the code that goes inside the void loop function is very simple. We are just going to call the Blynk.run() function.

{% code lineNumbers="true" %}

```arduino
void loop()
{
    Blynk.run(); // runs the Blynk API
}
```

{% endcode %}
