WEBVTT 00:00.150 --> 00:05.850 And now that you have a better understanding of digital things as output begins, let's quickly make 00:05.850 --> 00:08.900 a recap of how to work with editor. 00:09.300 --> 00:15.000 So here in our secret, we already have the plugged on PIN number 12. 00:15.510 --> 00:19.950 So the first thing I'm going to do is to do a defined. 00:21.620 --> 00:25.330 Define we've already been 12. 00:25.770 --> 00:33.920 I'm going to create a constant here, we've defined all uppercase with an underscore and then directly 00:33.920 --> 00:34.860 the value. 00:35.150 --> 00:42.560 So whenever we needed to use this number in our code for the NDP, we just need to write a dippin instead, 00:42.860 --> 00:50.740 which will make it much easier later on if, for example, we want to change the being where the entity 00:50.750 --> 00:51.510 is attached. 00:51.710 --> 00:58.820 So first that you use a defined to easily get access to the PIN number in your code and then in the 00:58.820 --> 00:59.090 set. 00:59.180 --> 01:06.650 So I'm going to remove that command in the set that you will use the pin mode function here to set the 01:06.650 --> 01:07.590 mood of the pin. 01:07.760 --> 01:11.150 So by now we have seen only the outputs. 01:11.180 --> 01:16.820 So the first parameter is the PIN number and then the mode. 01:16.820 --> 01:22.580 So the mode will be out, put all the keys and it should be OK. 01:23.090 --> 01:29.630 Once you have done that, the PIN twelve is defined as an output, not an input. 01:29.630 --> 01:38.630 B So from now on, after you have used the pin mode function, you can change the state of the pin and 01:38.630 --> 01:41.780 we can directly do that here if we want to geto. 01:42.140 --> 01:42.650 Right. 01:43.740 --> 01:51.780 Elegy in we've let's say hi, because it will be low by default, but we said the and once we have set 01:51.780 --> 01:57.620 the mode we can directly set the stage, whether high or low, don't know. 01:57.630 --> 02:00.290 Let's say in our program we want to make the energy drink. 02:00.300 --> 02:05.400 But first, when we start the program, we want the energy to be boiled on for three segments. 02:05.430 --> 02:08.880 So, for example, we can do Delate three thousand here. 02:09.690 --> 02:17.070 So we pour on the LCD, we wait for three Siggins and then we we enter the loop function and in the 02:17.070 --> 02:22.770 loop function will digital right in here. 02:22.770 --> 02:30.210 Maybe we are going to start with low and then wait for let's say five hundred milliseconds and then 02:30.210 --> 02:30.930 digital. 02:32.440 --> 02:39.500 Right in high wait for another five hundred milliseconds. 02:40.360 --> 02:45.850 All right, and we have our blink example right here, but nothing complicated, as you can see. 02:45.880 --> 02:52.390 First, we said the mode and once the mode is set, we can just change the state as many times as we 02:52.390 --> 02:52.810 want. 02:53.700 --> 02:56.620 Let's upload this program here. 03:01.450 --> 03:06.850 All right, and you should see Oladipo out on for three singles and now the lady is blinking.
