 From Thonny, I am going to start our traffic light code with the new breakout code block. Please bear in mind that in this example I am NOT using a Pico W variant.

+<color #ed1c24>*** IMPORTANT ***</color>

 First thing I need to do, because we want this code to run at Pico boot, is to save the file as <color #ed1c24>main.py</color>. The Pico understands that a file called main.py is to be run at boot.
