    QR Codes + Audio
    Tammy's Tech Tools

    Imagine students’ artwork hanging in your school’s hallway and beside each masterpiece is a QR code. When parents, students, and other teachers scan the code using a mobile device, they hear the student telling about themselves and the relevance of their art…

     Or what about a QR code in the back of a library book that allows you to hear a student’s review of the book? Or a QR code sent home to parents that allows them to listen to their 1st grader reading or telling a story?

    Sounds difficult, doesn’t it? Well, don’t worry — it really isn’t hard at all! I’ll give you two options for recording the audio files and will show you a couple of ways to “embed” them into QR codes.


    Two Options for
    Recording the audio file and generating a URL:

    Option 1:


    1. Go to the Record MP3 website.
      Note – The first time you use this site, you will need to click a couple of buttons to set it up. Just follow the on-screen directions.
    2. Record the audio.
    3. Click the “Save Recording” button.
    4. Copy the provided URL.

    Option 2:


    1. Use the free recording software, Audacity, to record the audio.
    2. Export the recorded audio file (use the default .wav format) and put it into your public DropBox folder.
    3. Right-click the file (within DropBox).
    4. Choose the DropBox option from the pop up menu.
    5. Select “Copy Public Link.”

     2 Options for
    Creating the QR Code:

    Option 1:

    Use an online QR Creator

    1. Go to an online QR Creator such as:
      – QR Hacker
      – Kaywa
      – GoQR
    2. Paste the URL that you copied above.
    3. Follow the on-screen instructions to create a QR code.
    4. Print the code!

    Option 2:

    Batch-Generating Codes in a Google Spreadsheet

    1. Create a Google form to “collect” the URLs of students’ audio file URLs. 
      For instructions, http://tammyworcester.com/batch-create-qr-codes-in-google-spreadsheet/
      Suggested fields:
      – First Name
      – Last Name
      – Notes
      – URL
    2. Follow the instructions to generate a QR code for each URL.
    3. Print the QR codes!



    What to do with the code:

    Once the code is generated, you can download it or just copy it and paste it into a document or webpage. QR codes can be read equally well from a computer screen or from a printed page!

    Ideas for using QR Codes:

    General ideas:

    • Put a QR code with your contact info on the back of your business card.
    • Doing a presentation at a conference? Put a QR code with a link to your online handout or website on the opening slide of your PowerPoint presentation.
    • Put a QR code on your holiday letter that takes the reader to your family photos on your Flickr page.
    • Attending a conference or class reunion? Put a QR code on your name tag with info about you!

     Educational uses:

    (Great if your students have access to mobile devices with cameras)

    • Audio QR codes: See Tammy’s Tip of the Week #114 for instructions and examples
    • Create a QR treasure/scavenger hunt in or around the school. Codes can be printed and mounted in various locations. Students scan a code to get their next clue.
    • Get your students quickly and easily to a website by projecting the related code or printing it on a handout.
    • Have a Google form you want your students to fill out on their iPod touches or cell phones? Just show the related code on your projector screen!
    • A QR code on the back of a book could “take” a student to a web page about the author or to page of book reviews. (You could print the codes on labels, or print them on paper and tape them to the book.)
    • A QR code in a learning station could take students to a web page with instructions, information, or even a video!
    • Displaying student artwork in the hallway? Add a QR code that provides additional information about the student-artist.

    What are QR Codes?

    A QR Code is a 2-dimensional bar code that can be easily generated and then decoded with a smart phone (or other devices.) When scanned/read, the QR Code can activate the opening of a web page, dialing a phone number, sending an email or text message, and more.

    How are QR Codes Used?

    QR codes are very common in Japan and Europe (and are becoming more and more popular in the United States) and can be found on posters, signs, magazines, menus, and many other places.

    Where to get a QR Code Scanner/Reader:

    Some phones and mobile devices come with barcode readers already installed.

    • You can also do a Google search for something like, “QR reader for Nokia,” or “QR Code scanner for Droid.”
    • Note – For iPhone users, there are a variety of free QR Readers in the app store. The one I’m using is called “I-nigma”
