The three programming palettes
To simplify its use, the programming palette has been
divided into three palette groupings: the common
palette [containing the most used blocks], the
complete palette [containing all of the programming
blocks}, and the custom palette [containing blocks you
download or create yourself}.
You only need to use the blocks below to complete the chal-
lenges. The color sensor blocks can be Found in the complete
palette, while the others are located in the common palette.
The software's help area has more information about the rest
of the programming blocks when you are ready to move on.
