1
00:00:00,180 --> 00:00:05,290
Go to lab 7 RC servo RC So it was demonstration.

2
00:00:05,400 --> 00:00:09,550
If you look here at the I've got the breadboarding here.

3
00:00:09,720 --> 00:00:13,900
I've got my three point three Volt to five volt conversion going on.

4
00:00:13,950 --> 00:00:24,690
I've got the two 39-A four transistors in there and I've got my four resistors the two one k on resistors

5
00:00:25,320 --> 00:00:30,770
and I've got 2.2 K on resistors in there as well.

6
00:00:30,770 --> 00:00:37,950
If you look at the circuit diagram I talked about in the video you'll be able to find a reference that

7
00:00:37,950 --> 00:00:39,090
schematic there.

8
00:00:39,450 --> 00:00:40,950
And here we go.

9
00:00:41,190 --> 00:00:47,250
Here's the bases to board with RC servo land completed and running on here.

10
00:00:47,520 --> 00:00:56,400
And what I've got here is you can see the 7:7 display this is displayed what my pulse with modulation

11
00:00:56,400 --> 00:00:59,910
output is in relation to the resolution.

12
00:00:59,910 --> 00:01:08,460
So we've got 8 bits of resolution meaning that this value will go from zero all the way up to that.

13
00:01:08,880 --> 00:01:10,880
And here I've got.

14
00:01:10,950 --> 00:01:18,660
You can see the 5 volts I'm pulling off of the bases is too bored to power the RC circle.

15
00:01:18,870 --> 00:01:26,360
And over here is brown wires the actual pulse with modulation output coming out of here and into the

16
00:01:26,360 --> 00:01:28,740
3.3 Volt to FEIBEL conversion.

17
00:01:28,740 --> 00:01:35,640
And this right here is a ground I'm pulling off here just to keep everything together and this right

18
00:01:35,640 --> 00:01:38,140
here is the actual servo.

19
00:01:38,400 --> 00:01:43,960
And so what I want to do here is I've got my Nabl pen which is low.

20
00:01:44,160 --> 00:01:46,890
So right now my output is enabled.

21
00:01:47,160 --> 00:01:48,930
And this right here is.

22
00:01:49,050 --> 00:01:51,560
So it should add purchase here.

23
00:01:51,860 --> 00:01:58,860
This should add up to five and this is Archie sort of a new push that a five year seniority servo that

24
00:01:58,940 --> 00:02:00,310
just changed position.

25
00:02:00,310 --> 00:02:06,450
So I keep pressing this because this is my nick right here I've got this switch locked into one which

26
00:02:06,450 --> 00:02:09,820
means that's going to add and my value will change on here.

27
00:02:10,020 --> 00:02:15,900
So as I keep pushing this value changes hands as that increases this won't change.

28
00:02:15,910 --> 00:02:23,150
Now I'm going to go ahead and go down down values who's down on the arse's servo.

29
00:02:23,190 --> 00:02:31,260
Now this thing goes all the way up to the RC service is limited in that it only has 150 degrees worth

30
00:02:31,280 --> 00:02:32,180
of rotation.

31
00:02:32,400 --> 00:02:35,460
And so I can't go up any higher.

32
00:02:35,460 --> 00:02:37,560
Like you'll see what happens.

33
00:02:37,770 --> 00:02:42,350
It'll keep falling until right now which is kind of the Maxson where we went down to zero.

34
00:02:42,350 --> 00:02:49,190
So if I go in here it's kind of all in back around and nothing's going to happen here because this artillery

35
00:02:49,270 --> 00:02:50,590
is an x value.

36
00:02:50,850 --> 00:02:56,710
So I have to get back down to lower pulse with modulation values to where it'll start recognizing.

37
00:02:56,840 --> 00:02:57,580
So yeah.

38
00:02:57,630 --> 00:03:04,950
Now now of a second of these guys or I can push this is the one button and I push this year to a smaller

39
00:03:04,950 --> 00:03:11,400
increments is larger increments and this enable although I couldn't put this off to say that this works.

40
00:03:11,490 --> 00:03:14,620
Put that off because it's output.

41
00:03:14,620 --> 00:03:15,310
I can push it.

42
00:03:15,340 --> 00:03:19,150
But Holsworth modulation up it stays locked in.

43
00:03:19,860 --> 00:03:23,010
But I can't press it on anything else.

44
00:03:23,040 --> 00:03:33,420
Now enable again and as you can see switches around and counting down so you see and you'll be able

45
00:03:33,420 --> 00:03:37,860
to tell it's working right away see you push your buttons here and you the hexadecimal map you'll see

46
00:03:37,860 --> 00:03:40,520
the numbers changing.

47
00:03:41,690 --> 00:03:44,170
Let's get down to value go see something wrong.

48
00:03:44,440 --> 00:03:52,280
And also to since you hook your Cicero and you'll see the push button you'll see it kind of change using

49
00:03:52,280 --> 00:03:59,470
his ups and down and once you going on you've successfully completed you.
