Introducing to programming LEGO® MINDSTORMS® EV3

Send the program "flow" back to an earlier point in the program, causing it to repeat some instructions.

Choose between two different possible sets of commands to run.

Repeat a branching decision quickly, to enable continuous control of the robot.

Run all the programs on the robot in a continuous cycle.

Click the Loop Block, then drag a box around the commands you want to put inside the Loop.

Select the blocks you want to put inside the Loop, then right-click and choose "Place in Loop".

Right-click in an empty area and choose "Make Loop" from the menu that appears.

Drag a Loop into the program, then drag commands into it.
