hcsr04 is a driver allowing to usea HC-SR04 ultrasound distance sensor

## Documentation

For full documentation, please visit [![Go Reference](https://pkg.go.dev/badge/github.com/raspberrypi-go-drivers/hcsr04.svg)](https://pkg.go.dev/github.com/raspberrypi-go-drivers/hcsr04)

## Quick start

```go

package main

import (

	"fmt"

	"os"

	"time"

	"github.com/raspberrypi-go-drivers/hcsr04"

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

)

func main() {

	err := rpio.Open()

	if err != nil {

		os.Exit(1)

	}

	defer rpio.Close()

	h := hcsr04.NewHCSR04(17, 27)

	h.StartDistanceMonitor()

	for {

		fmt.Println(h.GetDistance())

		time.Sleep(hcsr04.MonitorUpdate)

	}

}

```

## Raspberry Pi compatibility

This driver has has only been tested on an Raspberry Pi Zero WH using integrated bluetooth but may work well on other Raspberry Pi having integrated Bluetooth
