Each programming block has a conguration panel that lets you adjust the 
settings of the block for the specic actions that you want. When a block  
is selected in the work area, its conguration panel will be visible at the 
bottom of the screen.
By changing the parameters on each conguration panel, you can change 
how a particular block will behave. For example, to make your robot move 
faster, you can change the Power property on the Move block’s conguration 
panel.
The ve buttons on the Controller communicate from your computer to the NXT:
The Download button downloads the program 
to the NXT. You can then run the program 
from the NXT.
The NXT window button gives you access 
to the NXT’s memory and communications 
settings.
The Stop button stops a running program.
The Download and run selected button  
downloads and runs just a piece of your  
program’s code (e.g. a single block or just 
a few blocks). Select the blocks you want 
to test and click on the Download and run 
selected button. You will then be able to see 
how the small sequence of your program 
performs on the NXT without having to 
download the whole program. 
The Download and run button 
downloads a program to the 
NXT and then starts running the 
program.
