Click the green flag to go. Use the microphone on your computer to detect noise. The more noise you make, the higher Scratch will fly!
Thanks to Getting Unstuck for the idea for this project. I was inspired to use sound sensing by the project @mres demonstrated during his TED talk where a bat is controlled by the sound made by the audience. I'd like to make this project into a game where obstacles appear and move towards Scratch and the user has to try and control Scratch to avoid them or collect them. Feel free to remix and have a go yourself.
