We've just plugged in the power bank in the Raspberry Pi controller. Has it started? Is it doing something? Why is it not moving? Simply put the raspberry power a small red diode and it just emits light. Well, it's on, but it will do nothing else.

The electronics starts, but nothing much happens
When you power the Raspberry Pi you start the processor and it will try to process different instructions that are given to it. It tries to read the instructions from the memory. But since there is no memory installed currently on our microcontroller there is nothing that the controller could do. It is not consuming any energy (or at least very small). It is more or less in a standby mode.
Standby mode
The controller is ready to do something useful if we give it instructions to do something useful. The way we give it instructions is to record those instructions on the SD card and place the SD card in the controller. This will be something that we would do in the next section of the course.

Courses and lessons with this Tutorial
This Tutorial is used in the following courses and lessons
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 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$ and you could also use it in many of the other courses that we are planning to release.

Power and start the controller
We have two power sources (batteries) - one power source is for the controller, the Raspberry PI, and one power source is for the motors. What is the separation between the power sources and why it exists? Why do we need two power sources? We need the different power sources because there is not enough power otherwise.
