Great.
You can now make your Raspberry Pi and Arduino boards communicate between each other using serial communication.
This is already a strong foundation you have, and with this foundation, you will be able to create
all kinds of applications.
So what we're going to do from now on is to make progress towards the final project, which is a complete
intercom system using both Arduino and Raspberry Pi.
First, we will focus on Arduino functionalities, then Raspberry Pi functionalities.
And after that we will be ready to start the final project.
So let's begin this part on Arduino.
There are actually two sections here.
First, we will add all the components that we need for the project one by one for each component.
I will give you some basic explanation.
Okay.
And I'm not going to dive into details here because knowing how to create basic circuits and code with
Arduino is part of the prerequisite of the course.
The goal of this section is just to do some recaps and make sure that you have the correct circuits
and also that we can reach the next practice section where you will create programs to interact with
the Arduino functionalities from the Raspberry Pi.
So for some components, if you already know how to use them, feel free to skip the coding part.
If not, then watch the video to expand your Arduino knowledge.
You can also see those following videos as a quick help to come to if you are stuck in some of the following
activities or project.
All right, let's get started.
