And a whole lot more people

2 extensions supported officially in Scratch

            others available for Lego Mindstorms, Aduino, Lego Wedo, Pico Board or Scratch board, etc.

            Lego Wedo developed by Kindergarten group so Scratch can work with them

Can use Enchanting for Robolab and other modifications to Scratch, as well as others

            With all of the enhancements to Scratch, they work but cannot be uploaded to the website

For Pico board, connect it via USB, then go to Sensing in Scratch, check the slider sensor, and make cat move according to the slider value, with a forever loop and set x to slider sensor value

            Can make the cat jump by using the button pressed and changing y in a forever if loop

            Also, 4 resistance sensor values

            Example:

Forever loop,           

Play note value of sensor A = resistance sensor for .5 beats, using the clips along the strip of water

                        As resistance changes, the note changes

A search on Kinect2Scratch will get a free download for moving sprites from sensing body

            Using kinect game controller and Scratch

Now with Lego Wedo, can use tilt and distance sensors to make the bird fly across the screen

Can make all kinds of animations and games using these controllers

Forever

Set y to distance sensor value A

If tilt sensor value = 4,

            Change x by -5

If tilt sensor value = 2,

            Change x by 5

Forever

Moteor direction reverse

Motor on for 1 second

Will make the dragon’s mouth open and close

If go to sites for any of the physical controllers, can download the drivers, usually free
