Lego Wedo and Scratch Getting Started
In Scratch, go to Hungry Alligator
https://scratch.mit.edu/projects/63608914/#editor (the green light
needs to be on next to Lego Wedo- check you have clicked More
Blocks and Add an Extension. Hint: close any windows or tabs you
have open that you do not need)
Put your hand in the mouth. Here is what should happen
https://youtu.be/ovkAsdHp1jc See a screen shot of the code
below.
Change the sound to meow and put your hand in the mouth.
Record your voice so the alligator makes a different sound when
it chomps.
Challenge: Go to Lego Wedo Hungry Alligator Simulation Starter
https://scratch.mit.edu/projects/45245528/#editor Click Remix top
right. Share to our Studio. Put in a background. Write a program so
that when an actual Lego man moves near to your plastic alligator,
your actual plastic Lego alligator starts to bite! Hints: You could
use the code above as the base. You can walk a man (or your hand)
towards the lego plastic crocodile to cause it to snap. Then you
need to write script so that when the crocodile opens its mouth,
the man moves on your screen as well.
If you finish early, try and make some other programs using Lego
Wedo with either Scratch or the Lego Wedo software.
You can search in Scratch for Lego Wedo and Alligator: click
Projects and look inside for the code.
