One of the coolest features of Scratch is its ability to work with your computer's webcam. The ability to incorporate backdrops (in Scratch 2.0), backgrounds in Scratch 1.4, and sprites by taking pictures with the webcam has been a long-time feature of Scratch, including the current version. In this project, we'll incorporate webcam photos with a sound sensor on the PicoBoard.

Don't have a PicoBoard? Then I'll show you how to use the computer's built-in microphone.
