WEBVTT 00:00.150 --> 00:06.900 This is the solution of the previous activity where you have to pour the energy when the buttons pressed 00:07.140 --> 00:09.930 and power of the ready when the button is not pressed. 00:10.440 --> 00:12.690 So first things first. 00:13.020 --> 00:16.410 We are going to initialize here the beams. 00:16.650 --> 00:21.960 And before doing that, we are going to use define for being. 00:21.960 --> 00:28.890 So this is still PIN number 11 and another defined for button. 00:30.160 --> 00:32.530 Bean, which is number two. 00:32.890 --> 00:37.670 OK, so for every bean you are going to use in your speech, in your program here. 00:38.140 --> 00:41.530 Well, you can just add a define for each bean. 00:42.750 --> 00:54.450 And then in the set up, so here we're going to use spin mode to initialize the energy in order to output 00:54.570 --> 00:59.800 mode and in mode by the button appear. 01:01.750 --> 01:03.820 Or input mode. 01:04.210 --> 01:09.640 OK, so here the order is not really important, you just initialized all the feeds so you could initialize 01:09.640 --> 01:11.650 the energy first on the button first. 01:11.670 --> 01:12.390 It doesn't matter. 01:12.760 --> 01:19.200 And now that the pins are set up after directly after the pin, also here in the set up for your uncle 01:19.220 --> 01:27.100 in the loop function, we can start to rate the button state and we can start to control the the in 01:27.100 --> 01:27.610 the loop. 01:27.790 --> 01:36.370 What I'm going to do, I'm going to write if digital read button in. 01:36.880 --> 01:43.750 But if this is equal to high, OK, and make sure you use to equal sine OK. 01:43.750 --> 01:47.950 If you just use one equal sign you may have some weird arrows here. 01:49.110 --> 01:56.730 So to equal sign, if the balloon is priced so we can read this line as if the balloon is priced, then 01:56.730 --> 01:59.100 we are going to own the entity. 01:59.100 --> 02:00.270 So digital. 02:01.550 --> 02:06.050 Right, and then we've hired. 02:07.250 --> 02:20.270 And as if the button is not pressed, we're going to do digital right in with No. 02:21.690 --> 02:23.380 All right, and that's about it. 02:23.400 --> 02:29.790 So now let's verify, let's combine I'm going to name it activity three. 02:33.720 --> 02:40.170 OK, Don, combining so we don't have any Tarong and I'm going now to upload it occurred to out in the 02:40.230 --> 02:40.580 world. 02:40.610 --> 02:43.010 So again, make sure the board is correctly connected. 02:43.320 --> 02:44.880 I applaud the code. 02:45.390 --> 02:49.850 And now so you should see hear the energy. 02:49.860 --> 02:51.040 So nothing happens. 02:51.640 --> 02:53.190 It is pulled off. 02:53.490 --> 03:02.580 But actually the edit is put off because we are in the end here of the if OK, because the button state 03:02.580 --> 03:03.360 is low. 03:03.360 --> 03:05.370 So we pull off the. 03:06.110 --> 03:14.370 No, I'm going to press the pause button here and you can see the 3D both on OK, I release the push 03:14.480 --> 03:19.200 button and a press error I press. 03:20.200 --> 03:27.310 I really and every time I press, the energy would be put on and every time I release or every time 03:27.310 --> 03:30.380 the button is, the press diary is put up. 03:31.420 --> 03:31.840 All right. 03:31.840 --> 03:35.450 So that's the end of this activity again with this activity. 03:35.470 --> 03:41.650 You could have the first real example of how you can combine different hardware components. 03:41.690 --> 03:48.010 OK, for example, with input components and output components to make a smarter program which will 03:48.010 --> 03:52.120 take decisions depending on the status of your sensors. 03:52.330 --> 03:56.940 And here you can see a nice combination of digital and digital right functions.
