Trick or Treat

Goal: Halloween is almost here, so it is time to trick or treat! Make a WeDo trick-or-treater—how it looks and moves are up to you, but it must say “Trick or treat!”


Start date: October 1, 2015
Due date: October 31, 2015

Rules: Your trick-or-treater can be cute, funny, scary–whatever you want–as long as it says “Trick or Treat.” You may use only the sensors and motors from the WeDo kit. However, you are welcome to use multiple WeDo kits, additional LEGO pieces, and non-LEGO materials. For tips on using sound with the WeDo program, check out this snippet: Programming Sound.
