The Challenge

Successfully connect & reconnect the Lego EV3 robot to Scratch X. Use Scratch code to teach the robot some moves! (check out the videos above)
Share the workload with your group
Choreograph (plan out) an EV3 dance with music that combines movement of the robot with sound and visual effects on the computer screen.
Incorporate sensors in your code that allow the robot to interact with the environment.
SHOW OFF!!! Share your results in an edited video of your project! Use the video to show off the cool ways you solved problems with code and sensors!

Day 1: Connect the Robot

(Note to teachers - these instructions only work for robots that have already been paired. For instructions on how to connect your EV3's for the first time, click here.

Turn on your Robot. Double check that the bluetooth on your computer is working. (Remember, the robot should not be connected. It will connect itself in the next step).
Go to Scratch X. Click the Open Extension URL link and paste this text:
- http://scollovati.github.io/ev3_scratch/ev3_scratch_v9.js
- Wait until the light turns green under the "more blocks" menu.
Try some code!

Day 2: Make A Plan, Code the Robot & Save Your Work

Choose a song. Make sure you follow best digital citizenship practices. See below for details.
Make a plan for how your robot will dance.
Create a list of sprites, costumes, and other things you will need to create.
Reconnect the robot. Save your work - multiple times if you have to.

Day 3: Reopen your Project

Click here to view a poster that tells how to revisit a saved ScratchX project.

Tip 1: Turn the EV3 brick on first.

Tip 2: Use Safari

Tip 3. Be patient. It may take up to 60 seconds for your robot to connect.

Tip 4: Save each version of your project with a new number each day. That way if you need to go back to an old version, you still have it.

Day 4: Add Music

Fair Use and Share Alike Music

Tip: Don't add your music to your ScratchX file. It will overburden the system. Add your music into your video project.

Day 5: Add Sprites and Costumes

The video to the right shows how to export a Google Slide and import it into Scratch as a background. The same process works for a Google Drawing or other picture you may find on the internet.
