1 00:00:00,730 --> 00:00:02,320 Hello, and welcome to this new lesson. 2 00:00:02,590 --> 00:00:05,950 Now let's start by calling the first method. 3 00:00:06,490 --> 00:00:17,530 First, we need to read the incoming data so light humidity, flawed humidity equals, which is the 4 00:00:17,620 --> 00:00:19,870 object that we all have defined speed. 5 00:00:20,710 --> 00:00:21,430 Humidity. 6 00:00:24,200 --> 00:00:28,190 The next one is for float, for the temperature. 7 00:00:30,520 --> 00:00:32,980 By DHT Dot read. 8 00:00:34,900 --> 00:00:41,770 Then, Richard, now we have the humidity and temperature to send them. 9 00:00:42,970 --> 00:00:52,060 We can easily use the Vishwa write function that is going to Blink Library has a method called Vishwa 10 00:00:52,060 --> 00:00:56,890 Right, which is used to write vessels for reading into virtual pens. 11 00:00:56,890 --> 00:01:02,560 We have or we will define and configure and our playing up. 12 00:01:02,770 --> 00:01:09,730 So to do this, simply write Blink Dot Virtual. 13 00:01:11,800 --> 00:01:12,310 Right. 14 00:01:13,780 --> 00:01:18,760 Now, first, define the virtual pin. 15 00:01:19,810 --> 00:01:21,550 Let's call it V. 16 00:01:24,970 --> 00:01:27,820 Five, and we will send humidity. 17 00:01:32,620 --> 00:01:35,650 And we will do the same for the temperature. 18 00:01:41,010 --> 00:01:43,260 Let's call it the fourth. 19 00:01:44,260 --> 00:01:50,440 And let's and the temperature in its. 20 00:01:52,220 --> 00:01:59,510 That's it now, this is the first function now, the second function, what we will do in the second 21 00:01:59,510 --> 00:02:01,970 function is basically the same thing. 22 00:02:02,510 --> 00:02:04,070 We will be the water level. 23 00:02:05,270 --> 00:02:08,870 And we already defined two variables here and here. 24 00:02:11,080 --> 00:02:17,320 So the water level will equal analog read function. 25 00:02:19,630 --> 00:02:23,770 And this will equal analog. 26 00:02:24,900 --> 00:02:36,090 Reads Now we need to bring the two variables here at water level since our pin number and the salts 27 00:02:36,090 --> 00:02:37,200 and salt pin number. 28 00:02:40,920 --> 00:02:46,260 Now we have two analog readings and two map them, we can easily use this function. 29 00:02:46,770 --> 00:02:48,150 You cut out water level. 30 00:02:50,480 --> 00:03:04,040 Equal mob and inside the mob, you can add water level and the rains zero two thousand zero. 31 00:03:05,260 --> 00:03:10,420 Twenty five, now the same thing can be done for the. 32 00:03:11,570 --> 00:03:19,940 Moisture level will equal mob and will do the very same thing. 33 00:03:20,840 --> 00:03:32,300 We were right, most certainly will, and we would add zero 4000 the zero to five or let's make it 20 34 00:03:32,930 --> 00:03:34,340 hundreds make this one 20. 35 00:03:34,580 --> 00:03:35,430 Now this. 36 00:03:35,450 --> 00:03:41,000 These values are depending on my sense of readings and the range that I want to get. 37 00:03:41,420 --> 00:03:47,000 Now, depending on your type of sense of your data sheet, you need to make sure that you are choosing 38 00:03:47,000 --> 00:03:49,410 the right values. 39 00:03:49,910 --> 00:03:50,870 Now to know. 40 00:03:52,650 --> 00:03:54,960 The arguing malfunction. 41 00:03:56,870 --> 00:04:00,770 Let's take a quick look at its description now. 42 00:04:01,130 --> 00:04:10,310 The map is basically a way to put heat maps a number from one range to another that is a value from 43 00:04:11,930 --> 00:04:14,300 low would get map tool to law. 44 00:04:15,110 --> 00:04:15,620 Now. 45 00:04:17,880 --> 00:04:24,000 It does not constrain values to within the range, because out of range values are sometimes intended 46 00:04:24,000 --> 00:04:31,050 and useful, that constrains function may be used either before or after this function if limits to 47 00:04:31,050 --> 00:04:35,110 that energies are desired, depending on your end goal. 48 00:04:35,130 --> 00:04:38,700 You can either use the constraints function or don't use it. 49 00:04:39,300 --> 00:04:47,970 Now you can see here, the map will take a value and from law from high to low and to high, so it will 50 00:04:47,970 --> 00:04:54,600 turn the value from low total as you can see this to this. 51 00:04:55,440 --> 00:05:03,990 And from high to high, as you can see from this to this now, the value is done on bottom up from low. 52 00:05:04,050 --> 00:05:11,370 The lower bound of the values can range from high, the upper bound of the values current range to low, 53 00:05:11,910 --> 00:05:14,960 the lower bound of the values target range. 54 00:05:14,970 --> 00:05:19,680 The one that we want to high the upper bound of the values target range. 55 00:05:20,250 --> 00:05:22,710 Now, as you can see, this is an example code. 56 00:05:23,190 --> 00:05:29,430 We are mapping an analog value to eight bits zero to 255. 57 00:05:30,750 --> 00:05:33,000 As you can see, here we are reading the value. 58 00:05:33,210 --> 00:05:43,770 And here we are, getting the readings from zero to 1023 and we want them to be up to zero to 255. 59 00:05:44,340 --> 00:05:54,010 So one thousand twenty three will provide an output of 255 and will be stored. 60 00:05:54,070 --> 00:05:54,990 The value here. 61 00:05:55,590 --> 00:06:00,450 So it's basically a way to change from this range to this range. 62 00:06:01,320 --> 00:06:09,330 As you can see, and we are using the very same methodology here we are moving the values from this 63 00:06:09,330 --> 00:06:13,050 range from zero to 2000 to this range from zero to 20. 64 00:06:13,710 --> 00:06:16,740 And here we are, moving the values from zero to 4000. 65 00:06:17,100 --> 00:06:19,320 So this range from zero to 20. 66 00:06:19,890 --> 00:06:30,570 So very easy, straightforward and easy to implement, way to change the range from a very large range 67 00:06:30,570 --> 00:06:31,890 to a very small one. 68 00:06:32,370 --> 00:06:36,510 And they will both provide the very same final result. 69 00:06:37,690 --> 00:06:45,280 Now, this is regarding the mapping, and since we now have the water level and moisture level, we 70 00:06:45,280 --> 00:06:50,080 can easily send the values using the blank dot virtual. 71 00:06:51,280 --> 00:06:55,300 Right function here we have seven. 72 00:06:57,880 --> 00:06:59,290 Water level. 73 00:07:00,920 --> 00:07:02,150 And here we have. 74 00:07:08,520 --> 00:07:10,170 Let's say we six. 75 00:07:12,410 --> 00:07:14,320 To send the most shows. 76 00:07:20,050 --> 00:07:20,470 Hello. 77 00:07:22,700 --> 00:07:27,530 Now, let's verify the code to make sure that we don't have any spelling or. 78 00:07:28,990 --> 00:07:32,460 Promising, unassuming column for moving forward. 79 00:07:36,110 --> 00:07:39,200 OK, now, as you can see here, we have A.. 80 00:07:40,550 --> 00:07:43,100 We have a similar problem here. 81 00:07:53,180 --> 00:08:00,650 Hey, here we have I'm a bit cynical because I'm coding and see Python and Java. 82 00:08:02,250 --> 00:08:03,270 Sometimes. 83 00:08:04,400 --> 00:08:09,470 Such mistakes happens because, as you know, Python doesn't have a single column at the end of each 84 00:08:09,470 --> 00:08:10,070 sentence. 85 00:08:10,970 --> 00:08:11,330 OK. 86 00:08:14,350 --> 00:08:23,410 Now, Dan, combining everything is right now we can add an extra step here in this area and this extra 87 00:08:23,410 --> 00:08:29,230 three step will make sure that we are getting readings from the D.H sensor. 88 00:08:29,800 --> 00:08:35,140 But if you have connected it correctly, you won't need this step. 89 00:08:35,560 --> 00:08:37,600 You can add an if statement. 90 00:08:38,110 --> 00:08:43,510 If you are getting readings from that humidity and temperature, then move on. 91 00:08:43,600 --> 00:08:50,560 If not, then print a serial line, fail to read data from the sensor and you can do the same here. 92 00:08:51,370 --> 00:08:53,740 But I don't think that we need them now. 93 00:08:53,740 --> 00:08:57,290 We need to make sure that we memorize these numbers. 94 00:08:57,310 --> 00:09:04,710 We will give back to them in the blink explanation lesson. 95 00:09:05,860 --> 00:09:08,170 Now we are done with this. 96 00:09:10,740 --> 00:09:12,810 Function and we are done with this function. 97 00:09:13,530 --> 00:09:19,170 The next step is it's configuring the set up and the loop functions. 98 00:09:19,530 --> 00:09:23,370 And this will be an easy thing to do. 99 00:09:24,120 --> 00:09:27,510 Then we'll take an overall look this code. 100 00:09:27,780 --> 00:09:33,270 But let's summarize, or let's make a quick overview of what we have done here. 101 00:09:33,480 --> 00:09:41,520 We have used DST object to bring in the humidity and temperature since our values, and we have sent 102 00:09:41,520 --> 00:09:47,900 them to the blink using B5 and V4, which are their virtual pens. 103 00:09:48,950 --> 00:09:49,290 Sorry. 104 00:09:49,680 --> 00:09:57,450 Now we have used analog to need to read the water level and moisture level since the value, and we 105 00:09:57,450 --> 00:10:05,610 have used the map function to map the range from zero to 2000 to Al-Watan range, which is zero to 20 106 00:10:06,090 --> 00:10:07,680 and in the most liberal sense. 107 00:10:07,680 --> 00:10:14,730 Or we have used the map function to map these values from zero to 4000 to zero to 20. 108 00:10:15,230 --> 00:10:24,930 And then we have some values using the virtual write function and the library, and we use six and v 109 00:10:24,930 --> 00:10:32,070 seven as virtual pens for the blink up and the next lesson we will set up. 110 00:10:33,220 --> 00:10:38,940 We will write the code inside the setup and the loop functions to finish this coding process. 111 00:10:39,390 --> 00:10:40,250 Thanks for watching. 112 00:10:40,260 --> 00:10:43,890 If you have any question, please ask in the Q&A about.
