Scratch 2.0 could not interact with hardware devices directly. Instead, hardware extensions came with a helper app — a separate application that the user needed to install and run on their computer. Scratch communicated with the helper app via HTTP requests, and the helper app talked to the hardware.
A document (last updated: September 2013) had been drafted for Scratch 2.0 HTTP extension developers to describe the extension description file format — the protocol used to communicate between Scratch extension helper apps, and the extension development process. This specification was still preliminary, and was discontinued due to the release of Scratch 3.0.
The Scratch 2.0 extension mechanism was still under development, and the Scratch Team was still figuring out how the extensions will be shared and distributed. However, it was discontinued upon the release of Scratch 3.0.
