In this project, we continue the development of our Simon Says pattern-matching game by adding randomized LED blinking.
In our last project, we wrote some code to flash LEDs in a preplanned sequence. While that's a good start, in our Simon Says game, we're going to need to flash LEDs in a random sequence. This will require us to make some modifications to the code from the last project, which will give us a random sequence of LED flashes.
The hardware setup for this project should be the same setup that was
completed for the project. Here's a reminder:
Here is what the code for this project should look like at this point (with new changes highlighted with arrows). When you run it, you will see a random LED flash, then that light will repeat with a second random light added, then that 2-light sequence will repeat with a third added and so on (the sequence will continue until you stop the program):
Here, we've made the following code changes:
On Line 6, we import the randrange()
we'll need later.
On Line 14, instead of filling the play_order
list with our
predefined sequence of LED flashes, we're going to create an empty list
that we can fill with a random sequence of flashes.
On Line 20, we add a while
loop, so that we can continue to
generate a random LED flash and add it to the list each time through the loop.
This new loop will play the entire sequence of random LED flashes, add a
new flash to the sequence, play the list again with the new LED flash added, and
then repeat.
On Line 23, we append another random LED flash to the
play_order
list sequence.
