WEBVTT 00:00.210 --> 00:04.450 Let's now add the ultrasonics insult to our suit. 00:04.800 --> 00:09.840 So, again, first I'm going to do this on Tinker Cat and then show you with the real secret. 00:10.470 --> 00:16.070 So we're going to start not from an empty secret, OK, but we're going to start from the previous one. 00:16.080 --> 00:23.630 So the three areas where you have three, it is one potential murder and one push-Button connected to 00:23.640 --> 00:24.000 the original. 00:24.060 --> 00:26.160 So I'm going to duplicate that one. 00:28.760 --> 00:29.720 And they meet. 00:30.930 --> 00:32.910 OK, so Nick. 00:34.890 --> 00:35.490 Syncytial. 00:37.250 --> 00:43.580 All right, and let's find the ultra sonics and so in the component lists, I'm just going to take ultra 00:43.730 --> 00:45.150 sonic, OK? 00:45.180 --> 00:49.480 And you may see a few different ultrasonic components here. 00:49.730 --> 00:57.980 And actually, the one we are going to use is that what the H c dash s are OK for? 00:58.310 --> 01:02.360 OK, there is another one, which is not the same one. 01:02.360 --> 01:05.170 And you can see this one has only three things. 01:05.570 --> 01:08.390 However, the one we are using has four things. 01:08.540 --> 01:10.020 So remove this one. 01:10.460 --> 01:12.320 Just use that one. 01:12.320 --> 01:13.670 The H c. 01:13.970 --> 01:16.000 S are ok for OK. 01:16.580 --> 01:18.360 And what do we have here. 01:18.380 --> 01:20.350 So we have four different things. 01:20.720 --> 01:25.250 We have this is C, which is power, which would go directly to Five-fold. 01:25.820 --> 01:29.200 On the other end we have Genndy which is grong great. 01:29.210 --> 01:35.570 So we have ground, we have possibly and then we have two more pins here in the middle we have three 01:35.600 --> 01:38.210 which is Trigorin and equal. 01:38.510 --> 01:44.360 OK, so we are going to use I'm going to explain to you just a little bit later in the form listen how 01:44.360 --> 01:47.050 to use those two things basically to trigger pain. 01:47.300 --> 01:51.920 We are going to use it as an output to trigger the sensor and then the equipping. 01:52.010 --> 01:56.360 We are going to receive the data on that beam to get the distance. 01:57.020 --> 01:58.580 So let's connect. 01:59.530 --> 02:03.860 I'm going to put it here and have. 02:05.080 --> 02:06.370 Left, OK. 02:06.490 --> 02:14.110 Let's start by connecting the ground, the ground is here, all this line, I'm going to take the line 02:14.110 --> 02:17.620 here, the last one and do this. 02:17.620 --> 02:22.840 And actually what I'm going to do here, I'm going to make a small modification, so I'm going to put 02:22.840 --> 02:23.230 that. 02:24.440 --> 02:28.370 Here, I'm going to modify this wire here. 02:32.920 --> 02:35.110 So by clicking, you can add one dot. 02:39.430 --> 02:45.340 And I'm going to modify this year and one that year. 02:47.450 --> 02:48.800 That when we go here. 02:52.700 --> 02:56.840 And that when we go here, so I have just modified the secretes. 02:59.450 --> 03:01.290 So that's the exact same thing. 03:01.310 --> 03:06.590 OK, I've just connected the ground to a different pin and obviously two different being on the same 03:06.590 --> 03:09.590 line, OK, and that one is still connected to the ground. 03:09.770 --> 03:18.440 So I can just do this, connect the ground of the sensor to the ground here directly. 03:19.990 --> 03:29.230 And let's pretend like, OK, let's take the vesi on the second spin and let's connect it to this issue 03:29.380 --> 03:30.760 here with. 03:31.240 --> 03:31.630 Right. 03:32.980 --> 03:39.820 OK, and then we have the two beans here, so the trigger pin and eco thing, I'm going to connect the 03:39.820 --> 03:46.480 A.P. on digital pin number three, the Equipe handling of the ECOFIN. 03:46.480 --> 03:51.160 And let's let's find a way like this. 03:56.300 --> 03:57.600 OK, let's change. 03:57.620 --> 03:58.130 Carol. 03:59.390 --> 04:09.140 To four people, so make sure you use different colors so you don't mix the wires together and then 04:09.140 --> 04:17.350 so the equipment on number three and trigger pin, so that one, I'm going to take it and put it on 04:17.360 --> 04:19.150 PIN number four. 04:19.940 --> 04:21.040 Let's do this. 04:22.830 --> 04:23.850 In number four. 04:25.940 --> 04:32.130 And it's changed color also to Brown, OK, Brown looks good. 04:33.080 --> 04:38.700 So, as you can see, the more components you add to your secret, the more it can look a little bit 04:38.720 --> 04:39.310 messy. 04:39.770 --> 04:42.740 But with the correct colors, you should be fine, OK? 04:42.770 --> 04:47.930 Make sure that, of course, all of these dots are connected together. 04:48.200 --> 04:51.470 OK, here, all the grounds are connected together. 04:51.590 --> 04:52.460 OK, that's good. 04:53.090 --> 04:57.770 Then make sure you don't mix the wires together, ok. 04:57.820 --> 05:00.070 And the secret is done just one thing. 05:00.320 --> 05:06.500 So for the trigger and Escorpion, you can basically choose any digital thing, but actually not for 05:06.500 --> 05:12.230 the Equipe because for the eco pin, the PIN number three, if you remember on the adeno, is also a 05:12.230 --> 05:14.810 pin that can handle interrupts. 05:14.940 --> 05:17.660 OK, so you have been two and three that can handle. 05:18.590 --> 05:24.830 So it's important you plug the eco pin on an incorrect pin as well. 05:24.860 --> 05:31.460 OK, so if you have you know, that means in two or three, if you have a different ball, just check 05:31.460 --> 05:36.780 the listen on the interrupt section to see what pins you can use. 05:37.420 --> 05:37.760 Right. 05:38.300 --> 05:39.600 And now I'm just going to show you. 05:39.620 --> 05:46.700 So if I just start the code here, actually, let's remove any code we have. 05:49.440 --> 05:56.920 Run the code with nothing, just going to show you how you can use the ultrasonic sensor. 05:57.110 --> 06:04.520 So if you click on the ultrasonic sensor, you can see here, so you have the range with the angle and 06:04.520 --> 06:07.410 the range of where you can detect an object. 06:07.450 --> 06:11.240 OK, you can see here one hundred and thirty centimeter. 06:11.240 --> 06:14.410 You also have the range in inches, OK? 06:14.510 --> 06:17.410 And you can see you can move the objects. 06:17.420 --> 06:23.590 So you will be able to use this, OK, because in real life we will be able to do a real hardware. 06:23.600 --> 06:30.160 We will be able to measure directly by putting our hand on a wall on objects with simulation. 06:30.170 --> 06:36.860 You just put on the circuits with a simulation, you click and then you will be able to get an object 06:37.280 --> 06:38.780 in the range of the sensor. 06:39.110 --> 06:39.500 All right. 06:41.570 --> 06:46.290 And here is the real hardware secret with the ultrasonic sensor. 06:46.670 --> 06:53.120 So I have put the address and sensor here and so you can see we have the four different beams of ground, 06:53.120 --> 06:59.480 echo, trigger and viscously, and each one, which each is connected to a different line. 06:59.540 --> 07:03.310 OK, you can see here make sure you connect each to a different line. 07:03.320 --> 07:04.280 That's very important. 07:04.910 --> 07:09.710 Now, I have also but as you can see here with this on this direction. 07:09.830 --> 07:14.360 OK, so the sensor doesn't face any other component. 07:14.390 --> 07:18.840 OK, that's very important because with this and so we're going to measure a distance. 07:18.900 --> 07:21.450 OK, so the distance, for example, from my hand. 07:21.650 --> 07:29.270 So if you put it the other way or if you put it near something else, then you will always get an object 07:29.480 --> 07:33.190 in the middle and then you can't measure an accurate distance. 07:34.290 --> 07:36.870 So I have got to keep, as you can see here. 07:36.900 --> 07:42.260 So first, of course, the wire is disconnected and I have connected the ground. 07:42.270 --> 07:49.350 So the first you can see here ground here to the ground line, which is connected to the ground of the 07:49.350 --> 07:49.730 area. 07:50.220 --> 07:58.740 I have been connected the opposite and with the small right wire to the plus line with D.C., which 07:58.740 --> 08:01.460 is connected to five of them. 08:02.100 --> 08:09.140 And then I have so we have here you can see AECO first when he is on the right is coping, OK? 08:09.240 --> 08:12.080 So make sure you correctly check AECO is here. 08:12.120 --> 08:22.230 OK, you put Echo here and you go to PIN number three on the Alvino and then the trigger being OK, 08:23.070 --> 08:24.320 trigger that one. 08:24.330 --> 08:26.550 So make sure you get to the trigger. 08:26.550 --> 08:29.220 The same line as trigger pin goes to. 08:29.220 --> 08:33.810 I have chosen the orange wire goes to pin number four. 08:34.670 --> 08:37.310 OK, so that's four new wires. 08:37.320 --> 08:45.930 OK, one way out of the ground, one to see which is five-fold and then pin on pin number three which 08:45.930 --> 08:50.420 has the interrupt functionality and trying to pin on pin number four. 08:50.700 --> 08:52.320 And that's pretty much it.
