snowflake fall blocks challenges

Coding challenges for snowflake fall.

Before we get started

Complete the snowflake fall activity and your code will look like this:

Challenge 1

@video td/videos/snowflake-fall-1

Let's begin creating our falling effect by adding another snowflake with show LEDs that displays a different snowflake pattern after the first one. We need 2 frames in the new animation that display both the first and the second snowflake images.

• Run your program to see the cool animation.

Challenge 2

@video td/videos/snowflake-fall-2

To finalize our snowflake fall, let's add a different snowflake pattern.

• Run your program and see if it works.

Challenge 3

Add a fourth frame to the current animation... or make it your own!
