# setup()

The `setup()` function is called when a sketch starts. Use it to initialize variables, pin modes, start using libraries, etc. The `setup()` function will only run once, after each power-up or reset of the Maple board.

## Example

    int buttonPin = 38;

    void setup() {
      pinMode(buttonPin, INPUT);
    }

    void loop() {
      // ...
    }
