WEBVTT 00:00.150 --> 00:06.000 In this new activity, you are going to practice with the infrared remote controller and actually you 00:06.000 --> 00:12.810 are going to mix that functionality with the LCD display screen and with the different LCD that you 00:12.810 --> 00:13.740 have on your circuit. 00:14.040 --> 00:17.860 So once again, we are going to create a multi functionality application. 00:18.120 --> 00:20.620 So what will you need to do here? 00:21.210 --> 00:27.330 So you will need to map some buttons of your infrared remote controller. 00:27.720 --> 00:35.080 We need to map the button zero, one, two, three, and then the button func stop. 00:35.100 --> 00:36.490 Or does the button stop? 00:36.520 --> 00:39.690 OK, that's the buttons we are going to use. 00:39.720 --> 00:42.420 So one, two, three, four, five buttons. 00:42.600 --> 00:45.420 And no one's to get the mapping from those numbers. 00:45.540 --> 00:49.150 You are going to associate a different action for each number. 00:49.170 --> 00:55.060 So if you press on zero, what you're going to do is clear all editors. 00:56.110 --> 01:00.880 Or just power of all entities. 01:00.940 --> 01:09.540 OK, so you're going to use the three entities if you press one, you are going to toggle energy on 01:09.820 --> 01:12.730 12 that to having to call any one. 01:14.140 --> 01:19.390 So a little girl, I mean that if you press the button, then you are going to put her on the egg and 01:19.390 --> 01:22.890 if you press the button again, you are going to pour out of the edit. 01:22.990 --> 01:26.440 So you are going to need to keep the status for the eight as. 01:26.560 --> 01:33.910 OK, then to you are going to toggle 82 until 11. 01:34.240 --> 01:40.600 And when you press the three, you are going to get any three on been there. 01:41.290 --> 01:47.830 So one, two or three to toggle the LG one, two or three and then zero to pull off all the entities. 01:47.950 --> 01:53.710 Then once you are going to do also is to set up the LCD display screen. 01:53.920 --> 01:59.130 And whenever you do an action, you are going also to print something on the screen. 01:59.230 --> 02:08.170 So whenever you do something on the first line and see the first line, you are going to print just 02:08.170 --> 02:09.450 the number you receive. 02:09.520 --> 02:13.570 So print the the value add to the data, the command. 02:15.310 --> 02:16.070 That's your receipt. 02:16.480 --> 02:18.670 And on the second line. 02:20.400 --> 02:21.420 You are going to print. 02:22.450 --> 02:32.590 The text for the action used to, for example, forgive eligible, OK, just as an example to and two 02:32.590 --> 02:41.670 to three poll of all trades and one additional nothing that you going to do is if you press on the button, 02:41.680 --> 02:46.480 think or stop, you are going to clear, Nancy. 02:46.990 --> 02:52.840 So if you press that button you don't interact with the edit is you just clear whatever is on the LCD 02:52.840 --> 02:53.210 screen. 02:53.530 --> 02:53.890 All right. 02:53.900 --> 02:55.450 So make sure you go step by step. 02:55.600 --> 03:01.840 For example, first, you can set up the infrared remote control to map the numbers. 03:01.840 --> 03:09.580 Do the switch case are effective structure to go through all of the commands and then toggle the entities 03:09.580 --> 03:15.130 accordingly and after that, to use the entity to inform the user of what you have done? 03:15.130 --> 03:22.810 So step by step and also what I'm going to do is for the elves that is on the code, I'm going to use 03:23.020 --> 03:25.540 arrays and functions. 03:26.110 --> 03:33.370 So I'm going to put the three entities inside the ring so then I can set all the modes for just one 03:33.370 --> 03:33.850 function. 03:34.060 --> 03:39.790 I can pull off all it is and I can use the index also one, two or three. 03:39.790 --> 03:43.410 I can use the index on the array to toggle the editing. 03:43.780 --> 03:44.190 All right. 03:44.200 --> 03:47.290 And I will see you in the next lesson from the solution.
