Item-3
A player that lets go of the button before the light turns green gets an unreasonably
good score (1 ms). Your microcontroller needs to figure out if a player is cheating.
Pseudo code was introduced near the end of Activity #3 in this chapter. Here is some
pseudo code to help you apply an

What’s an algorithm? An algorithm is a sequence of mathematical operations.
What’s pseudo random? Pseudo random means that it seems random, but it isn’t really.
Each time you start the program over again, you will get the same sequence of values.
What’s a seed? A seed is a value that is used to start the pseudo random sequence. If you
use a different value (change value from 23 to some other number), you will get a different
pseudo random sequence.
