1 00:00:00,720 --> 00:00:05,640 Let's have a quick look at the wiring before we move on to the software side of this project. 2 00:00:06,600 --> 00:00:13,350 I've got my completed project on a report, and just to make it easier to make reference to individual 3 00:00:13,350 --> 00:00:13,570 pins. 4 00:00:13,960 --> 00:00:15,930 I've got my pin map right here. 5 00:00:16,350 --> 00:00:22,600 So I've got the orientation the same as well between the pin map and the actual hardware. 6 00:00:23,710 --> 00:00:31,320 Also having a look at the documentation that I have provided that the header of each script you see 7 00:00:31,320 --> 00:00:36,930 there, I've got a listing of the connections here, the components and where those should be connected. 8 00:00:37,380 --> 00:00:46,650 I have chosen the OLED screen and the sensor that can both be part of the same ice quazi interface. 9 00:00:47,130 --> 00:00:53,250 The particular screen that I'm using is the page one one zero six OLED. 10 00:00:53,670 --> 00:00:58,920 It has a one hundred and twenty eight by 64 pixel resolution. 11 00:00:59,160 --> 00:01:07,110 And I chose this particular city because from a previous testing, I know that it works well on hardware. 12 00:01:07,510 --> 00:01:08,870 I see. 13 00:01:09,150 --> 00:01:15,050 So that means that I can be a little bit more efficient as compared to using software I could see. 14 00:01:15,420 --> 00:01:21,350 I had also tested the image two hundred and eighty sensor to make sure that it does work with hardware. 15 00:01:21,810 --> 00:01:22,560 I squared. 16 00:01:22,560 --> 00:01:28,560 See, apart from the efficiency of hardware, I could see this as software. 17 00:01:28,560 --> 00:01:32,610 I could see also wanted to economize on the amount of chip away. 18 00:01:32,610 --> 00:01:33,710 So using the breadboard. 19 00:01:33,720 --> 00:01:41,280 So I wanted both peripherals to either be connected together on the same software I could see interface 20 00:01:41,280 --> 00:01:43,710 or hardware R-squared interface. 21 00:01:44,070 --> 00:01:47,780 So I was able to find the components that match all of those criteria. 22 00:01:48,330 --> 00:01:52,650 So the way that this works is I've got pins 18 and 19. 23 00:01:52,980 --> 00:02:01,500 And as you can see from the documentation here, for the ease with the 32 and micro python, the hardware, 24 00:02:01,500 --> 00:02:12,210 it's quite seabass and there are two interfaces, interfaces with IDC zero has S.L nine, 18 and state 25 00:02:12,780 --> 00:02:19,350 of 19, that these are these two pins right here, Tapio 18 and 19. 26 00:02:19,680 --> 00:02:24,330 And I just broken out those two pins on the two sides of the Bridport. 27 00:02:24,330 --> 00:02:32,040 One goes to the OLED display and the other one goes to be EMY to remove that section which under it. 28 00:02:32,670 --> 00:02:35,760 But just be careful with the pins. 29 00:02:36,000 --> 00:02:42,810 Very often I personally mix the ground and the pins in this case basically. 30 00:02:42,810 --> 00:02:51,390 And Genndy for the display, it can be a little bit sometimes confusing, but take a bit of time, take 31 00:02:51,390 --> 00:02:56,910 care to make sure that you have broken out the correct pins to the correct columns on the breadboard 32 00:02:57,390 --> 00:02:59,190 and then you'll be good. 33 00:02:59,190 --> 00:03:03,300 So I'm going to plug in the welded back onto. 34 00:03:04,760 --> 00:03:13,540 Britain would take good care, sure, they are properly lined, another criteria that are used to select 35 00:03:13,540 --> 00:03:18,510 the components was that they wanted them to be on the same logic level and the same power level. 36 00:03:18,780 --> 00:03:24,480 So both this display and the sensor can operate on three point three volts. 37 00:03:24,600 --> 00:03:32,530 So I didn't need to use the five four vote output pin on the E.S.P 32 as I would if I had used the 16 38 00:03:32,550 --> 00:03:34,680 by two LCD display. 39 00:03:35,340 --> 00:03:43,190 So with all of the above said, the wiring, as you can see, is fairly simple and just straightforward. 40 00:03:43,470 --> 00:03:51,280 There was a minimum wiring necessary finally for the idea of just connected reality to a 21 year old. 41 00:03:51,300 --> 00:03:52,510 It just shows me activity. 42 00:03:52,530 --> 00:04:00,060 It just shows me with time that the script is taking a reading from the sensor or sending data to efficient 43 00:04:00,060 --> 00:04:02,820 that in order to trigger the notification email. 44 00:04:03,800 --> 00:04:07,800 OK, so let's compare it with the wiring and the hardware. 45 00:04:07,940 --> 00:04:16,640 Let's move on to the next lecture where we'll talk about the script in its first version, a situation 46 00:04:16,640 --> 00:04:20,050 where a whole lot is stored in a single file.
