# How to pass a callback function as an argument (Arduino, C++)

This makes use of the `std` C++ library

```cpp
bool myCallback(int value) {
  // here your custom logic
  return status;
}

void myFunction(std::function<bool (int)> callback) {
  // here your custom logic
  bool status = callback(3);
}

void loop(void) {
  myFunction(myCallback);
}
```
