Lego EV3 Quick Tips

The drive block helps you move around.  This will drive the motor for a set number of rotations - click it for more options like on/off, on for seconds or on for degrees.

Drive 2
You can control the speed and direction of each motor by changing these values.

Drive motors
Make sure your motors are plugged into the right spots - B & C for this block!

The loop block (look in the orange section) is very useful.  Here we run the motors for 1 second and then check if the colour white is found by the colour sensor ([6] is the white colour, you can change the options).
Note that the colour sensor is plugged into port 3.  Check the different options you have available!
