00:00:00,810 --> 00:00:06,370
Let's have a quick look at how way to display the world in the sense that I want to be, especially

2
00:00:06,390 --> 00:00:13,590
to when I was looking for the appropriate components for this project, I wanted components that are

3
00:00:14,040 --> 00:00:15,640
easy to connect to.

4
00:00:15,690 --> 00:00:21,270
That means the least amount of wiring is necessary, the fewest possible wires.

5
00:00:21,690 --> 00:00:28,790
And then the next step from that is to also try to use the least number of communications interfaces.

6
00:00:29,250 --> 00:00:37,300
So based on components that I have played with and examined in the past, I was able to find the BMY.

7
00:00:37,590 --> 00:00:47,520
Two hundred and eighty sensor and the squid see two by 16 character display the LCD display that both

8
00:00:47,520 --> 00:00:50,940
work on the squid sea communications interface.

9
00:00:51,180 --> 00:00:58,260
And I've also tested them so that I can confirm that both of them work on the E.S.P 32 hardware interfaces

10
00:00:58,260 --> 00:00:59,760
instead of software interfaces.

11
00:00:59,970 --> 00:01:05,280
Some of the other displays that I've played with the already displays in particular would only work

12
00:01:05,280 --> 00:01:07,230
on the software interface.

13
00:01:07,540 --> 00:01:15,060
So if that was the case, then I would need to use a hardware I could see and a software I could see

14
00:01:15,060 --> 00:01:15,660
interface.

15
00:01:15,660 --> 00:01:18,630
And that again would require Maguires that I wanted to avoid.

16
00:01:19,110 --> 00:01:25,430
So this combination is ideal hardware interface for the display hardware interface with a sensor.

17
00:01:25,680 --> 00:01:36,780
Both of them go on to interface with the zero which work on on Jupitus 18 and 19, as you can see here

18
00:01:36,780 --> 00:01:38,580
as well, in the micro python.

19
00:01:38,580 --> 00:01:46,650
That limitation for the specific two, we have to hardware, it's could buses and using this one here

20
00:01:46,650 --> 00:01:52,710
at Pince GPO 18 and 19.

21
00:01:53,520 --> 00:02:00,330
So I've done the necessary connections are used jumper wires to break out those two panes, connect

22
00:02:00,330 --> 00:02:03,520
them to the sensor into the city.

23
00:02:03,960 --> 00:02:11,600
Now, one point of differentiation between the two devices is that sensor is a three point three foot

24
00:02:11,610 --> 00:02:12,210
device.

25
00:02:12,420 --> 00:02:21,420
So I've connected to the three point three volt power array here, which takes power from this pen right

26
00:02:21,420 --> 00:02:23,850
here on the east, three to three point three volts.

27
00:02:24,600 --> 00:02:28,410
The LCD screen, though, requires five volts.

28
00:02:28,410 --> 00:02:33,600
So I got that from the five both pin on the ASPCA to buy this green wire.

29
00:02:33,960 --> 00:02:38,340
So I was able to power the LCD that way.

30
00:02:38,760 --> 00:02:46,950
The ground, of course, for both devices is the same for the activity entity that's connected to Tapio

31
00:02:46,950 --> 00:02:53,760
21 with a two hundred and twenty on current limiting resistor to ground.

32
00:02:54,060 --> 00:02:57,780
So the anode is connected to CHIBBARO twenty one.

33
00:02:59,140 --> 00:03:01,420
And that's it with the hardware, fairly simple.

34
00:03:02,020 --> 00:03:05,760
Let's move on to the next election to have a look at the screen.
