When we create a program in the LEGO SPIKE Prime software, there is always one orange block in it, it is the starting block "when program starts". But what does it do?
This block is the first in the orange EVENTS section, and it says that all the blocks after it will be executed on an event. What is this event?
The event for this block is the start of the program from the hub, and that's why the block is called the when program starts, because when the program starts, all the blocks after it will be executed!
