What are the indications that the Raspberry Pi controller has started? Pro Preview

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.
