Your Android Smartphone is now a Scratch Sensor Board
Scratch is a graphical programming environment that makes it easier for kids (ages 8 and up) to create their own interactive stories, games, animations, and simulations. The new Scratch Sensor app for the Android Smartphone allows kids to now interact with their favorite stuff toy.
Connections between Scratch and other programs are made using the Scratch networking protocol. With this feature turned on, a program can also send broadcasts and global variables into Scratch. The Scratch Sensor uses the Scratch networking protocol to send the Android Smartphone accelerometer and compass sensor information and broadcast two states (jump and walk) to Scratch.
