I'm working with a 28BYJ-48 step motor. Instead of ordering the ULN2003 Motor Driver board, I ordered a ULN2003 Darlington IC. After looking at tons of pages and videos, I see most of the tutorials use the motor driver board. I've ordered it and am waiting for it to show up. In the meantime, I thought I'd try replicating the motor driver board if it turns out that I have the parts on hand.
Using this schematic:
There's a capacitor at 10µF. What is the purpose of that capacitor?
This other diagram doesn't show a capacitor, but I'm not sure that I'm looking at the right schematic:
Is there anything else that, as a newbie, I may not realize is missing?
Really appreciate any help or nudges in the right direction. Thanks!
