WEBVTT 00:00.180 --> 00:06.570 This is the date of the final project, and in this state, what we want to do is to say that we can 00:06.570 --> 00:08.870 also unlock the application. 00:08.880 --> 00:16.650 So when it is locked, we can also unlock the application when we press on the play button of the infrared 00:16.650 --> 00:17.720 remote control. 00:17.970 --> 00:19.440 So we would have two choices. 00:19.710 --> 00:25.290 Either we unlock with the push button, which is on the breadboard, or with the play button on the 00:25.290 --> 00:26.080 remote control. 00:26.760 --> 00:32.820 So to do this well, I'm going to need to check if the command we receive is the play command. 00:33.030 --> 00:33.960 And actually it is. 00:34.170 --> 00:37.500 So I'm going to create the switch. 00:37.800 --> 00:42.450 So create an empty switch for all the different commands and then handle the play. 00:42.690 --> 00:43.130 Come in. 00:43.500 --> 00:48.230 So cute in the loop. 00:48.450 --> 00:53.220 So instead of removing the line, which is going to command this, because that can be useful later 00:53.610 --> 00:54.990 and then so we have the command. 00:55.660 --> 01:04.260 I'm not going to override the switch directly in the volume here and keeping it simple just to do the 01:04.260 --> 01:05.540 high level conditions. 01:05.550 --> 01:09.480 OK, check the time functionality and call the different functions. 01:09.810 --> 01:12.840 So I'm going to create a new function instead. 01:12.840 --> 01:15.180 I'm going to put it there. 01:16.770 --> 01:25.330 Void handled, I commend and get along, come in as a. 01:28.890 --> 01:37.500 And what I'm going to do is call this function here so Ariki I can do Hendel I recommend refiguring. 01:38.490 --> 01:44.340 And that's it for the volume, so we don't need to do anything else would just get the grunter with 01:44.340 --> 01:47.470 Decode, we get the comen without the comment to another function. 01:47.490 --> 01:50.220 Then in that function, we handle the command. 01:50.760 --> 01:57.360 So I'm going to switch with the command and I'm going to take each case. 01:58.140 --> 02:00.990 So I'm going to go back to the beginning. 02:01.020 --> 02:06.300 Let's let's just copy and paste that here for. 02:08.840 --> 02:12.830 Just like this, we have the defense and then I'm going to remove it, so Jake. 02:13.870 --> 02:14.920 First case. 02:17.780 --> 02:23.540 And then do so here, which we're going to do is take a look and then break. 02:25.530 --> 02:28.800 And then case with the signature of. 02:30.270 --> 02:38.880 It I'm simply going to put to do here, so we are going to fill those twos in the following steps. 02:40.160 --> 02:42.860 Kees, EQR. 02:45.440 --> 02:48.020 And then to the break. 02:49.100 --> 02:49.700 Jas. 02:52.290 --> 03:01.140 So that can be a little bit repetitive here, but once it's done, it's done, she's done. 03:02.280 --> 03:03.060 But don't. 03:04.710 --> 03:05.190 To do. 03:06.640 --> 03:11.300 Right, and if you make sure that you correctly create the switch structure at the beginning, then 03:11.300 --> 03:12.910 you would not have any problem here. 03:13.160 --> 03:13.800 It's clean. 03:14.150 --> 03:17.870 Now, I can add any functionality without breaking the switch. 03:18.260 --> 03:19.550 And, of course, default, 03:22.760 --> 03:27.150 I think a default, even if inside we do nothing. 03:27.410 --> 03:33.980 So the default, basically, if we receive documents that if we press on a button that is not defined 03:33.980 --> 03:34.260 here. 03:34.490 --> 03:35.930 Well, what do we want to do? 03:36.260 --> 03:38.270 Well, in this application, we want to do nothing. 03:38.270 --> 03:39.860 So I do nothing. 03:39.860 --> 03:47.030 But I started writing the default book because this is a super best practice and. 03:48.000 --> 03:53.050 Let's remove that, of course, and now we have our switch. 03:53.490 --> 04:00.630 So what I can do is complete this current step by unlocking the application when I press on the play 04:00.630 --> 04:01.020 button. 04:01.710 --> 04:08.340 And to do that when it's super, super simple, because we already have all the lock and unlock mechanism 04:08.340 --> 04:10.980 working with functions that we can call directly. 04:11.010 --> 04:15.510 So what I can do is code unlock function and that's it. 04:16.320 --> 04:18.070 So where is the function? 04:18.090 --> 04:26.030 It's here in that function which check if it's locked, if yes, we unlock the application and we pull 04:26.040 --> 04:26.490 out of the. 04:29.710 --> 04:37.780 So basically so this comment actually can be he's not in the is not OK, if it's not, this can be called 04:37.780 --> 04:38.360 anytime. 04:38.530 --> 04:39.490 So basically. 04:41.730 --> 04:48.810 This, whenever you press the button, play it, we call the analog function, whether it's locked are 04:48.810 --> 04:54.960 not locked, but then because you have this check, if it's locked, then it's not a problem. 04:54.960 --> 05:01.080 If you just press on the play button and it's not locked, it's just going to do nothing. 05:01.500 --> 05:03.710 OK, so now everything is ready. 05:03.750 --> 05:04.580 I can just. 05:04.590 --> 05:11.640 So that's the verified code with final project step number eight already. 05:14.460 --> 05:18.600 And Kate's done compiling lists of blue code. 05:20.090 --> 05:27.550 So we have initializing and then the application with no physical outputs or obstacle here wanting, 05:27.890 --> 05:34.240 and then I go to closed obstacle price to unlock, what I'm going to do is press on the play button, 05:34.280 --> 05:34.630 OK? 05:35.210 --> 05:38.890 And you can see now the application is unlocked. 05:39.200 --> 05:46.160 So if I press on the play button, OK, you can see here the right energy is on means that we receive 05:46.160 --> 05:51.110 some data, but nothing happens simply because, well, it's not locked at the moment. 05:51.550 --> 05:57.050 So now, again, I put an obstacle that is going color press to unlock. 05:57.050 --> 05:59.990 I can unlock again with this play button. 06:00.330 --> 06:01.350 I can also. 06:01.430 --> 06:03.410 So that's the application again. 06:03.890 --> 06:06.430 I can press the button here. 06:06.470 --> 06:07.790 That's the same behavior. 06:08.910 --> 06:10.790 All right, and that's the end of the steps. 06:10.860 --> 06:19.080 Now you have two ways to unlock the robot on the application directly on the breadboard with the remote 06:19.080 --> 06:19.560 control.
