Let's think
Start every code with the “Start Block.”
The “Start Block” is the point where your code begins to run.
Rules of the Start Block
- Code does not run without a Start Block.
- Every code must have the Start Block at the very front.
- You can use only one Start Block per stage.
Show the solution
When the start block runs, the Master Block shows red and the LED block shows a smiling face.
