Building an Arduino system from scratch
Let's now see how to build an Arduino system on a breadboard using the components we
chose.
There are several components to assemble, so the best thing to do is follow the instructions
from the following schematic diagram that summarizes all the connections you have to
make:
I recommend putting the Arduino microcontroller (ATmega328) first in the middle of the
breadboard so you can add the different components around it. This schematic illustrates
the placement of the different components:
The following image shows a fully assembled system with the battery pack:
