Quite a bit of cleanup for Lesson 2. Primary changes include:
A correction where the documentation referenced the incorrect pin compared to the image
Included a better flow for the pinout diagram, and a diagram more consistent with future lessons
Added clarification for physical pins versus logical pins (for example, GP pins) which is important for this lesson and later lessons
Cleaned up the flow of how the user updates their code. Instead of having multiple python files, the learner instead builds from the first onboard LED and adds code as they go along. The conclusion is a snippet of what their final code would look like.
Consolidated the challenges to be consistent with other lessons
