WEBVTT 00:00.180 --> 00:04.170 And a new entity to practice with the communication. 00:04.500 --> 00:11.580 So we decided we are going to use one entity from the secret we have and decided communication to send 00:11.580 --> 00:14.890 a number from the computer to the original. 00:15.150 --> 00:18.590 And so what you are going to do first is very simple. 00:18.750 --> 00:26.820 The first step is to make the blink ring the ability so you can choose any entity you want to be in 00:26.820 --> 00:27.660 2011. 00:28.210 --> 00:29.250 It doesn't really matter. 00:29.250 --> 00:30.630 Just make an entity blink. 00:30.780 --> 00:36.420 And then, of course, you need to choose a delay to set a frequency for the week. 00:36.960 --> 00:39.520 And here is where you will you say communication. 00:40.140 --> 00:46.980 So the value you have in the delay in Michigan will be the value that you send of the cell communication 00:48.060 --> 00:48.410 here. 00:48.930 --> 00:55.580 When we send a number, let's say send 300 or we press enter and this will become the new delay. 00:55.770 --> 01:00.570 And during the execution of the program, every time we send a new number, this will become the new 01:00.570 --> 01:00.990 delay. 01:01.970 --> 01:03.610 We can do is in the loop. 01:03.720 --> 01:11.360 We will use what we've seen before to read data from the cell communication and then use the bus information 01:11.360 --> 01:12.200 to get a number. 01:12.200 --> 01:18.020 And this number we're going to delete also because there will be no value set at the beginning when 01:18.020 --> 01:23.300 you run the program where you just start the program so you can use a default value, OK, for the first 01:23.300 --> 01:27.650 time until you send a value through the sale communication. 01:27.890 --> 01:32.540 Also, to make things a little bit more interesting, you will need to validate. 01:33.830 --> 01:36.620 Validate the user input. 01:36.770 --> 01:44.270 OK, because the delay, we're going to say that the delay can only be between one hundred milliseconds 01:44.660 --> 01:51.860 and one thousand milliseconds so that the only values that we are going to accept. 01:52.610 --> 01:57.740 So if you send here a delay of 10 milliseconds, that will not work. 01:58.290 --> 02:00.780 Send one thousand three hundred. 02:00.920 --> 02:02.480 That will not work either. 02:02.870 --> 02:08.160 OK, so you need to validate the user input to make sure it's between one hundred and one thousand. 02:08.510 --> 02:08.860 All right. 02:08.870 --> 02:11.750 And I will see you in the next lesson for the solution.
