WeDo 3 Castle
We made a castle out of LEGO bricks, and set it up on top of a laptop, so the scratch project can act as a backdrop. The LEGO WeDo controls a motor that can raise and lower a drawbridge on the castle. There's a sensor in the tower of the castle, so that when the LEGO person goes up there, the scratch project makes the sky turn to night time, and it plays some sleepy music.
This project uses the LEGO WeDo. You can find more information about it here:
