Functions & Global Variables | Raspberry Pi Pico Workshop: Chapter 3.6

🔗 *The full course* : _https://core-electronics.com.au/courses/raspberry-pi-pico-workshop/_

In this video, we are going to learn all about *functions* in *MicropPython* . Functions are just a way of storing a piece of code away, giving it a name, and then running that code when we call its name. This is a great tool to use when we have sections of *code* that need to be *repeated*. We will also be covering some tricky caveats when dealing with functions, namely; parameters, arguments, and *local and global variables*.
