Ideas for Improvement

• A common confusion occurs between the "Only one" block (which disables other LEDs) and the "Each" block (which does not disable other LEDs).
  • A possible solution to reduce this confusion would be to remove the "Only one" block, and teaching students to set the value to <0, 0, 0> to avoid a trail of lights. Perhaps we should also include a "Clear All" block if taking this approach.
  • Another solution is to edit the text of the blocks to be more explicit as to the difference in function.
• Adding a random number generator could be interesting. Suggested implementation is to make a block that sets a variable to a random integer (either 0-255 or within a specified range). This would allow us to tie the RNG into the lesson about variables.
• A block to create a color gradient could also be interesting.
