Setup
Before getting started, make sure you have the following parts.
Step 1
Attach the RFID Phidget to your computer.
Download Audio Files
Click HERE to download the audio files. After downloading, unzip the file as shown below.
Write Code (Java)
Copy the code below into a new Java project. If you need a reminder of how to do this, revisit the Getting Started Course.

import com.phidget22.*;
//Add other libraries for sound
import java.io.File;
import javax.sound.sampled.*;
public class SoundEffects {
public static void main(String[] args) throws Exception {
//Define tags and audio
String cheerTag = "TAG_ID_HERE";
AudioInputStream cheerAudio = AudioSystem.getAudioInputStream(new File("PATH TO CHEER AUDIO HERE"));
//Create
RFID rfid = new RFID();
//Open
rfid.open(1000);
//Use Phidgets
while (true) {
if (rfid.getTagPresent()) {
System.out.println("Tag Detected: " + rfid.getLastTag().tagString);
if (rfid.getLastTag().tagString.equals(cheerTag)) {
Clip clip = AudioSystem.getClip();
clip.open(cheerAudio);
clip.start();
Thread.sleep(clip.getMicrosecondLength() / 1000);

Console.WriteLine("Tag Detected " + rfid.GetLastTag().TagString);
if(rfid.GetLastTag().TagString == cheerTag)
{
System.Media.SoundPlayer player = new System.Media.SoundPlayer(cheerSound);
player.PlaySync();

Coming Soon!
In the code above, you need to add the following information:
- cheerTag: This is the RFID tag ID that will be associated with the cheering sound. If you don't know your tag ID values, go to the RFID Device Tutorial, run the provided code and copy/paste the tag ID.
- cheerSound: This is the file path to your cheer sound. E.g. "C:/Users/Downloads/sounds/cheer.wav"
After you have updated your code with the proper tag ID and the file path, try running your code. When you tap the correct tag, you should hear cheering!
Practice
- Assign the other RFID Tags to the Applause sound effect and the Boo sound effect.
- After adding the other sound effects, you may notice that your code has many repeated statements. Try creating a function that takes in an audio clip and plays it to reduce your code size.
- Using buttons from your Getting Started Kit and music files, try to replicate the functionality of the Juuke
