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

arduino.on('ready', function () {
    
    // Access the temperature sensor on pin A0
    var thermometer = new five.Thermometer({
        controller: 'LM35',

    // Data event listener with callback function
    // Will capture incoming sensor readings
    thermometer.on('data', function () {

        // Callback has readings in celsius, fahrenheit and kelvin
