I know this is a huge request, but any help anyone could provide would be hugely appreciated. I don’t have any prior education in electronics but after seeing this,
https://www.youtube.com/watch?v=sO2-tqoyGik&list=PLxJ6sdzlzhixE-ENZhnilJT8l4VZag-gt I had to make one for myself. I know it’s a lot to begin with, but I’m fairly certain that if I can work out a parts list I can get it assembled in the proper order. I’ve been going by this tutorial,
https://www.youtube.com/watch?v=e7OPWbbpQ_o&list=PLxJ6sdzlzhixE-ENZhnilJT8l4VZag-gt&index=2 and his schematics but I’m having a bit of a hard time understanding how they fit together. The 2 schematics in his videos plus the one he posted on a website are:

C:

I understand A well enough, but are B and C 2 separate ways of doing the same thing or are they both parts of the same whole? It seems there are no voltage regulators in B, but there is no op amp in C, and the final project uses both regulators and an op amp.
Also, I’ve worked up what I think is most of my parts list, please forgive the uninformed terms but does it look complete?
1 - Pancake Motor
1 - Can Motor
2 - 10 ohm resistors for motors
RGB LEDs
3 – 5k trimmer resistors for LEDs
Audio Jack and Plug
4 – 1k potentiometers
3 - on off toggles
1 - on off on toggle
2 - 5k trimmer resistors for duty cycle on PWM
3 - caps for duty cycle toggle: 0.1uf, 0.01uf and1.0uf
1 - Filter Cap (size?)
555 timer
Op amp
2 - voltage regulator
2 – 5k trimmer resistors for regulators
12v power supply
Thank you again, I know his how to videos end up being 25 minutes so its a lot to ask but any tips will help.
