For powering the motors we would use the batteries that are in the remote control car. Not the power bank, but the batteries. We should connect the batteries to the Motor Driver

TL. DR.
Connect battery GND to driver GND and battery VCC to driver VCC
Where are the GND (minus) and VCC (plus) on the driver?
Below is the driver with two of the Connectors are highlighted. The one on the left is the 12V+ (plus). The one on the right is the GND (minus). Check them out.
Connect the GND cable from the batteries to GND connector on the Driver
I know, I know. We are starting to get a little technical. We would not even tell you that the official name for this connectors is "Terminal Block PCB connector", but we would just call them connectors. In the next few tutorials, we would even introduce you to the scheme of the driver and you will learn the "official names" and "designations" of this connectors. For now, let's connect the driver to the batteries and then we would discuss.
Counting from left to right on the picture. Batteries holder VCC(plus) from the Switch to the first Connector. GND (minus) cable from the batteries holder to the first connector.
You might have to bend the pins of the cables a little if necessary.
The red cable is the VCC (plus) and the brown cable is the GND (minus)

Perfect STEM course. Module 1 - Smart Car with Raspberry PI
Disassemble a remote control car. Change the brain of the car with a smart computer like Raspberry Pi. Build a smart device with artificial intelligence that you could control from your phone and that could freely navigate itself in the real world and on the Internet. Use your hands. Develop programs for your robot and your phone. Be curious and invent.
The perfect course lives up to its name. You move through the content, we check it and return feedback to you.
In the end, you should be able to better understand how to program and design smart devices that would make the world a better place. For everybody age 12+, 16+, 21+, 35+, etc. The hardware costs about 150$. It changes through the years so it might take some time for you to find it as Raspberry PI, motor drivers, power banks and h-bridges.. they change. Note that the course was designed to be led by a teacher with a decent knowledge in embedded hardware and software. This, on the other hand should not stop you, if you are curious.

Connecting batteries to the Motor Driver
Every electronics tutorial, book or course about Raspberry Pi or Arduino will use a motor driver. Very few of the courses will actually explain why do you need a Motor Driver, what is it for?
