I am geeking out right now. Those project files are using mBlock. They just opened the mBlock program that I downloaded last week for my mBot (from the MakeBlock Kickstarter) EEEeeee!! I am going to be doing some major mBot, Scratch, LittleBits cross over classes now. My kiddos are always wanting to build their own robots and now with LittleBits Arduino bit using mBlock, I will be able to extend my "0 to Roboticist" program one step more. Now I can't decide whether to dig more into the Scratch content on the forums or go write some more content for my classes. Did I mention geeking out!!
