Sorry if the title is annoying but this forum can be confused with Advanced Topics forum. Connecting to the Physical World forum is about mechanics which allow offline machines to interact with Scratch, Advanced Topics forum is about tricks online which can zoom you above the limits of Scratch.

If you plan to post a topic here about stuff rather than connecting Scratch to the physical world, redirect yourself here.

Scratch on!

Bump!

I do not get it
