Thanks for the quick replay, the pdf is about 28BYJ-48 model it's comes with 5 pins, but I need 28BYJ-28 it comes with 4 pins.

@salmanfaris I've not used the same version of the stepper motor that you've mentioned but I've used 12V stepper motor with ULN2003 motor driver. So probably I can help you with the queries.
Firstly all the tutorials on the internet show how to connect your motor's wires to ULN2003. But, in reality when you buy those motors the wires color codes may be changed, so in that case, we need to use a multimeter and check the resistance of the wires. 2 wires will have the same resistance and other 2 wires have the same resistance and the leftover one is a ground wire. This way we can get to know which wire must be connected to which port of ULN2003 driver. This is the common doubt all get while using ULN2003.
What are objects?
Jeff Goodell: Would you explain, in simple terms, exactly what object-oriented software is?
Steve Jobs: Objects are like people. They’re living, breathing things that have knowledge inside them about how to do things and have memory inside them so they can remember things. And rather than interacting with them at a very low level, you interact with them at a very high level of abstraction, like we’re doing right here.
Here’s an example: If I’m your laundry object, you can give me your dirty clothes and send me a message that says, “Can you get my clothes laundered, please.” I happen to know where the best laundry place in San Francisco is. And I speak English, and I have dollars in my pockets. So I go out and hail a taxicab and tell the driver to take me to this place in San Francisco. I go get your clothes laundered, I jump back in the cab, I get back here. I give you your clean clothes and say, “Here are your clean clothes.”
You have no idea how I did that. You have no knowledge of the laundry place. Maybe you speak French, and you can’t even hail a taxi. You can’t pay for one, you don’t have dollars in your pocket. Yet I knew how to do all of that. And you didn’t have to know any of it. All that complexity was hidden inside of me, and we were able to interact at a very high level of abstraction. That’s what objects are. They encapsulate complexity, and the interfaces to that complexity are high level.
This webinar is focussing on learning Git VCS, a distributed version control system for tracking changes during practical software development.
We will be exploring the usage of various git commands, plugins/extensions and branching-models based on real-world contexts.
The session is targetting absolute beginners with minimum or no experience with git, But a mindset to optimize and improve work efficiency and productivity by learning and exploring new tool-chains and strategies is a must!
