For full documentation, please visit [![Go Reference](https://pkg.go.dev/badge/github.com/raspberrypi-go-drivers/button.svg)](https://pkg.go.dev/github.com/raspberrypi-go-drivers/button)

## Quick start

```go

import (

	"fmt"

	"github.com/raspberrypi-go-drivers/button"

	"github.com/stianeikeland/go-rpio/v4"

	log "github.com/sirupsen/logrus"

)

func main() {

	err := rpio.Open()

	if err != nil {

		os.Exit(1)

	}

	defer rpio.Close()

	b1 := button.NewButton(17)

	if err := b1.EnableEventDetection(); err != nil {

		log.WithField("error", err).Error("impossible to enable edge detection")

	}

	for event := range b1.EventChan {

		if event == button.Pressed {

			fmt.Println("Button pressed")

		} else if event == button.Released {

			fmt.Println("Button released")

		}

	}

}

```
