In the following lessons, you will learn how to detect a distance with you and we know using an ultrasonic
sensor.
But first, congratulations, you have just finished the second part of the course where you learned
more interesting functionalities.
Now you have a very good foundation.
Those functionalities will help you create more complex project and understand how to work with different
hardware components.
And now let's start the third part of the class, and this part will be quite fun.
You will experiment with different hardware, sensors and actuators.
Those components are a bit more complex than the classic and is, for example.
But they will also allow you to discover very useful functionalities.
We will start with the ultrasonic sensor with which you can measure distances.
Then you will use an LCD screen to get some Real-Time text feedback directly on your Arduino secret.
You will discover how to control your of application with an infrared remote controller.
And finally, how to get the luminosity of the environment using a photoresistor sensor.
And because the whole course is built with a step by step approach where each building block leads to
another, you will see that with those components we will use all the concepts, tools and techniques
that we have seen so far.
You will practice more.
We've secured building programming, digital and beans, cell time functionalities, multitasking,
interrupts, etc..
So before you start this part of the course, make sure you have correctly finished the previous spots.
But don't worry too much.
If you don't have a 100 percent understanding of everything right now, that's not really a problem.
You will better understand all the previous concepts in this new part and during the following sections.
If you still have any doubt, come back to the previous sections to refresh your memory on a concept.
Rewash the explanations are also redo the practice exercises and after finishing to explore those new
hardware components, you will have finished the third part of the course and you will work on the final
project.
As you can see, we are almost there.
So now let's focus on the first section of this new part, the ultrasonic sensor.
In this section, you will add the ultrasonic sensor to your secretes and then discover how to control
the sensor so you can measure a distance between the sensor and an object or a wall.
With some activities, you will improve the way to read the distance using interns.
And you would also practice by using EDS and ultrasonic sensor in a single application.
And let's start.
