A quick look at Power Output of different LEGO Robotics motors. The NXT to the EV3 to the Spike Prime motors. What does it mean for your robot performance? Get the doc here.
LEGO EV3 Classroom Software (Scratch)
If you've tried to do complex programming with the EV3 Classroom app, you may be finding it let than clean. I went searching for a reference guide just for the basic command blocks and wasn't finding one. However, there is a Scratch reference guide that at least will give you the information you need for things like the Event, Control and Operators blocks. You just have to ignore all the info that doesn't apply to the classroom. The Move and Motion block sets in Scratch have been replaced by the Motors and Movement block sets in EV3 Classroom.
