1
00:00:00,880 --> 00:00:07,379
Well, I'm going to explain you how to use Cocodrive.

2
00:00:07,379 --> 00:00:14,980
I know that you must download it and unzip the program and then open the folder and you

3
00:00:14,980 --> 00:00:18,160
can see the Cocodrive icon.

4
00:00:18,160 --> 00:00:22,660
Click in Cocodrive Algorithm and you can see this screen.

5
00:00:22,660 --> 00:00:30,500
So you can choose between Pictures and Symbols, but in this level you must use Symbols.

6
00:00:30,500 --> 00:00:41,280
So click in Symbols and as you can see in Cocodrive you can see the different components

7
00:00:41,280 --> 00:00:45,060
organized into different categories.

8
00:00:45,060 --> 00:00:58,479
For example this is Power Suppliers, Switches, Input Components, Passive Components, Output

9
00:00:58,479 --> 00:01:15,299
components, gears and rotational mechanism, meters or different ways to do measures.

10
00:01:15,299 --> 00:01:27,060
So in this case we are going to choose the suppliers, the power suppliers, and in this

11
00:01:27,060 --> 00:01:37,879
case it doesn't, current, supply or supply it, so you must change its value, 5V, then

12
00:01:37,879 --> 00:01:49,260
you must choose a switch, a simple switch, that can be this one, or push, something to

13
00:01:49,260 --> 00:02:03,819
push you must also choose the motor and where is the motor well the motor is here in with gears

14
00:02:04,780 --> 00:02:13,020
you have one motor one constant speed motor some torsion so the first one

15
00:02:15,259 --> 00:02:17,580
and then with the mouse

16
00:02:17,580 --> 00:02:31,379
just only click the button and moving you can join the different parts of the

17
00:02:31,379 --> 00:02:48,479
circuit using a wire so if you switch or turn on the switch the motor can move

18
00:02:48,479 --> 00:02:54,860
but in this case we need apart from the motors and gears so here you have

19
00:02:54,860 --> 00:03:03,919
different mechanisms, one of these is gears, take gears and join to the motor

20
00:03:03,919 --> 00:03:16,659
and obviously I need a reduction mechanism so the output gears need to be

21
00:03:16,659 --> 00:03:28,039
bigger than the input gears, and to do this I can change the number of teeth.

22
00:03:28,039 --> 00:03:34,419
So now you have the circuit, and that is the first part.

23
00:03:34,419 --> 00:03:45,639
You can do a photo of the circuit, you can do a screen capture of the circuit, or you

24
00:03:45,639 --> 00:03:57,780
You can, if you want, create a document, a Word document or some paper, or another document

25
00:03:57,780 --> 00:03:59,520
if you want.

26
00:03:59,520 --> 00:04:09,240
Because the second part of the exercise consists in doing a very simple calculation.

27
00:04:09,240 --> 00:04:16,600
If I want to know the intensity current, I need to measure, because obviously the motor

28
00:04:16,600 --> 00:04:22,839
is under 5 volts, it's the only supplier.

29
00:04:22,839 --> 00:04:33,959
So here in meters, I'm using the cocodile, I can insert an amperimeter that lets you

30
00:04:33,959 --> 00:04:39,160
to know the intensity current.

31
00:04:39,160 --> 00:04:47,939
if you want, it's not necessary, but if you want you can also use a voltimeter to know

32
00:04:47,939 --> 00:04:50,740
the voltage in the motor.

33
00:04:50,740 --> 00:04:59,220
One, the amperometer, is connected inserting into the circuit.

34
00:04:59,220 --> 00:05:10,220
This type of connection is usually called as serial connection, where as the voltimeter

35
00:05:10,220 --> 00:05:15,060
needs to do in parallel connection.

36
00:05:15,060 --> 00:05:27,899
So now if you switch you can know the intensity current, that in this case is 275 mA, and

37
00:05:27,899 --> 00:05:30,939
the voltage in the motor.

38
00:05:30,939 --> 00:05:37,600
So if you want to know the resistance in the motor, you need to use Ohm's law, and it's

39
00:05:37,600 --> 00:05:45,779
very easy, because in this case, resistance can be calculated using this law.

40
00:05:45,779 --> 00:07:02,740
The problem is, I am going to add the test, well, what I have said is that resistance

41
00:07:02,740 --> 00:07:07,980
is voltage, intensity current.

42
00:07:07,980 --> 00:07:19,279
So now to do the calculation I insert the values, voltage is 5, and intensity current

43
00:07:19,279 --> 00:07:33,439
is 1A is 1000 mA.

44
00:07:33,439 --> 00:07:40,420
So you must take this into consideration, if you do the calculation the result is this.

45
00:07:40,420 --> 00:07:56,670
The letter is OM, it's a Greek letter, but the result is this.

46
00:07:56,670 --> 00:08:06,209
So you have the, it's as simple as that, you must do the exercise and the exercise is as

47
00:08:06,209 --> 00:08:07,750
simple as that.

48
00:08:07,750 --> 00:08:23,560
You can then save as this format or if you want you can insert the photo, the picture

49
00:08:23,560 --> 00:08:40,539
in a test document if you want and submit this file and that's all, that's all that

50
00:08:40,539 --> 00:08:49,299
you want that's all that you must do in this first exercise I hope it can be

51
00:08:49,299 --> 00:08:55,860
useful for you I hope this can be useful
