1-1 Binary Secret Code - Introduction to Abstraction

We are moving on to Standard 6 which is about levels of abstraction. To understand what is meant by that, we're starting with a secret message in binary code

In this video, Mr. Weinberg introduces the idea of abstraction and teaches you to use Python to decrypt this binary code.

3-1 Introduction to State Machine Programming

Based on what you did last time analyzing the code of a microcontroller board and accelerometer, this video introduces how the concept of a state machine makes this code more modular and easier to debug. The idea is to refactor the code that deals with inputs, outputs, and the logic into separate functions. This abstraction makes it easier to build more complex programs than you might otherwise be able to program.
