Raspberry Pi Pico MicroPython Chapter 4 - Updated

Chapter 4 is an introduction to Physical Computing, using the onboard LED, External LED and External Push Button Switch.

I like to show additional content and terminology so that you are able to take the next step on your own. Most of us will go to the internet to find projects we would like to build. This requires us to use some one else's python code.
Hopefully by introducing you to different terminology and reference materials this will enable you to understand the more advanced and complex code you will encounter. (I'm sorry this makes the examples more complex than required, but you may "hopefully" thank me latter).

Update: I am now using the whiteboard to add graphics to help with the explanations.
