WEBVTT 00:00.180 --> 00:07.410 In the following lessons, you will learn how to detect a distance with you and we know using an ultrasonic 00:07.410 --> 00:07.980 sensor. 00:08.580 --> 00:14.940 But first, congratulations, you have just finished the second part of the course where you learned 00:14.940 --> 00:17.480 more interesting functionalities. 00:17.700 --> 00:19.940 Now you have a very good foundation. 00:20.250 --> 00:26.640 Those functionalities will help you create more complex project and understand how to work with different 00:26.640 --> 00:27.690 hardware components. 00:27.930 --> 00:33.920 And now let's start the third part of the class, and this part will be quite fun. 00:34.230 --> 00:38.540 You will experiment with different hardware, sensors and actuators. 00:38.910 --> 00:43.110 Those components are a bit more complex than the classic and is, for example. 00:43.410 --> 00:48.390 But they will also allow you to discover very useful functionalities. 00:48.630 --> 00:53.520 We will start with the ultrasonic sensor with which you can measure distances. 00:53.820 --> 01:01.260 Then you will use an LCD screen to get some Real-Time text feedback directly on your Arduino secret. 01:01.650 --> 01:07.300 You will discover how to control your of application with an infrared remote controller. 01:07.590 --> 01:13.740 And finally, how to get the luminosity of the environment using a photoresistor sensor. 01:13.920 --> 01:20.790 And because the whole course is built with a step by step approach where each building block leads to 01:20.790 --> 01:27.090 another, you will see that with those components we will use all the concepts, tools and techniques 01:27.330 --> 01:28.760 that we have seen so far. 01:29.100 --> 01:30.200 You will practice more. 01:30.210 --> 01:37.500 We've secured building programming, digital and beans, cell time functionalities, multitasking, 01:37.500 --> 01:38.970 interrupts, etc.. 01:39.510 --> 01:45.360 So before you start this part of the course, make sure you have correctly finished the previous spots. 01:45.780 --> 01:47.520 But don't worry too much. 01:47.520 --> 01:53.280 If you don't have a 100 percent understanding of everything right now, that's not really a problem. 01:53.460 --> 01:59.430 You will better understand all the previous concepts in this new part and during the following sections. 01:59.640 --> 02:05.760 If you still have any doubt, come back to the previous sections to refresh your memory on a concept. 02:06.070 --> 02:13.920 Rewash the explanations are also redo the practice exercises and after finishing to explore those new 02:13.920 --> 02:20.460 hardware components, you will have finished the third part of the course and you will work on the final 02:20.460 --> 02:21.090 project. 02:21.390 --> 02:23.620 As you can see, we are almost there. 02:24.300 --> 02:30.510 So now let's focus on the first section of this new part, the ultrasonic sensor. 02:31.080 --> 02:37.230 In this section, you will add the ultrasonic sensor to your secretes and then discover how to control 02:37.230 --> 02:42.840 the sensor so you can measure a distance between the sensor and an object or a wall. 02:43.050 --> 02:48.300 With some activities, you will improve the way to read the distance using interns. 02:48.480 --> 02:55.170 And you would also practice by using EDS and ultrasonic sensor in a single application. 02:55.320 --> 02:56.250 And let's start.
