Recording audio/ creating qr code

If you are doing this on a mac, you won't need a microphone because there is a built-in. If you want to do it on your pc I have a microphone headset you can borrow or you can get cheap ones at Best Buy or Wal Mart. They are probably $12.00. 

If you record audio and create a QR code this way, it will expire in a month or two so don't do it for a keepsake project. There is a different way to do it that adds a couple more steps. This is just a quick and easy way to add tech to any project.
