Very helpful. Ya, I have been watching more videos where they break down these concepts in depth. My plan is to get this item (https://www.amazon.com/gp/aw/d/B08N4R48LJ?ref=ppx_pt2_mob_b_prod_image) to use as my external power supply. It comes with a DC terminal connector, which from my knowledge could be used with my breadboard. Does this seem plausible??
