How to use the johnny-five.Proximity function in johnny-five

board.on('ready', function() {
  const proximity = new five.Proximity({
    controller: PiIO.HCSR04, // Custom controller
    triggerPin: 'GPIO23',
    echoPin: 'GPIO24'

    console.log('cm: ', this.cm);
  });
});

board.on("ready", function() {

    //Create new Ping and show distance on change
    var ping = new five.Proximity({
        pin: 7,
        freq: 200,
        controller: "HCSR04"
    });

    var piezo = new five.Piezo(11); // leostick piezo

    var intervalID = 0;

    ping.on("change", function( err, value ) {

        console.log('Object is ' + this.cm + ' cm away');
        // now we do a callback on the interval of the centimetres thus
        // shorter centimetres means less interval before calling the tone command
        clearInterval(intervalID);
        if (this.cm > 4) {  // this is arbitrary to stop the conflicts with tone.

board.on('ready', function() {
  var proximity = new five.Proximity({
    controller: 'HCSR04',
    pin: 7 // Digital pin 7
  })

  proximity.on('data', function() {
    console.log(this.cm + ' cm at ' + new Date())
    // noisy data? You can use a smoothing algorithm:
