If you want to delve deeper into microcontrollers, I would highly encourage you to check out Jens’ channel: Friendly Wire:
   • How to build a binary clock  

I began my code with Jens’ and modified it to work with my specific needs. One of the additions was to program the clock to cycle all the tubes (count down) once every 12 hours. This is a preventative measure against ‘cathode poisoning,’ where if a cathode (digit) isn’t used for an extended period of time, it will develop some visible degradation. The most significant hour’s 2 through 9, and the most significant minute’s 6 through 9 do not get used when displaying the time and must be ‘exercised’ to prevent cathode poisoning.

The code is written in C. But C is a high-level language that cannot be interpreted by the microcontroller. Therefore, the MPLab IDE from Microchip is able to compile the C language into hexadecimal machine code that the microcontroller knows how to read. Furthermore, Microchip’s IPE is used to flash the .hex file onto the microcontroller.

Also, I may have used some electronic nomenclature that might not be known to all viewers:

Binary: A numerical notation of base 2 that can represent computation logic of on and off.

0 = 0
1 = 1
10 = 2
11 = 3
100 = 4
101 = 5
110 = 6
111 = 7
1000 = 8
1001 = 9
etc.

Bit: One binary digit (I just realized this is a portmanteau). For example, 1b (the ‘b’ means in binary) is one bit, 100b is three bits, 1001b has four bits (affectionately known as a nibble, or nybble).

IC = Integrated Circuit: More commonly referred to as a ‘chip’, is a generic term used for a manufactured circuit that could contain any number of components and functionality. The Microcontroller is an IC, which is many times more complex than the decoders, which are also ICs. However, they look very similar.

Breadboard: A useful platform for prototyping electronic circuits quickly, without soldering.

Perf Board = Perforated Board: A blank slate to build a prototype or one-off more permanently than a breadboard.

PCB = Printed Circuit Board: I didn’t use a PCB for this project, but sometimes I called the perf board a PCB out of habit.

Cap = Capacitor

V_DD: The conventional name for the power supply pin of an IC.
