00:00:02,540 --> 00:00:14,539
Firstly, we are going to do the report of the project in which you can see how it works.

2
00:00:14,539 --> 00:00:30,539
In general, that is only something that has an alternative movement and sometimes it stops and then a LED lights.

3
00:00:30,539 --> 00:00:36,140
So it's very easy and it is what you can do.

4
00:00:36,140 --> 00:00:42,539
The first step we have made using Tinkercad

5
00:00:42,539 --> 00:00:51,140
because it's the design of the bird that is part of our river.

6
00:00:51,140 --> 00:00:57,640
So I think it's easy to understand because it's a very, very simple design

7
00:00:57,640 --> 00:01:02,200
and you can do easily using Tindercad and its tools.

8
00:01:09,799 --> 00:01:16,920
We have one very easy structure also that supports all the parts of the project

9
00:01:16,920 --> 00:01:33,920
such as the lever, with an axe, and in the lever you have the burn, which is the resistance of the lever.

10
00:01:33,920 --> 00:01:44,920
And the other mechanism is an eccentric, so the eccentric is capable to move the lever, because they are connected.

11
00:01:46,920 --> 00:02:03,159
Apart from this we have also an electronic mechanism which consists in a board, in a

12
00:02:03,159 --> 00:02:14,120
control board with two digital outputs that are the LED and the servo motor.

13
00:02:14,120 --> 00:02:24,120
We also have one input, which is time, but it's not something that you can touch, because it's something that happens, that only happens.

14
00:02:29,120 --> 00:02:43,120
So, with this we must create, we must program this electronic circuit, and to program this electronic circuit we can use the BigBlock platform.

15
00:02:44,120 --> 00:03:06,120
The platform is based on blocks, similar to Scratch and App Inventor, so we have firstly to create and to indicate the control board that we are going to use

16
00:03:06,120 --> 00:03:14,120
and also the input and output and how we are going to connect it with pins

17
00:03:14,120 --> 00:03:19,120
and after that we create a very simple program

18
00:03:19,120 --> 00:03:26,120
which is just only to move on stops in alternative mode

19
00:03:26,120 --> 00:03:32,120
because it is repeating all the time without any stops

20
00:03:36,120 --> 00:03:47,000
With all of these parts, the project works as you can see in the last part of the video,

21
00:03:47,000 --> 00:03:49,120
in the results.

22
00:03:49,120 --> 00:03:56,860
I think it's easy to understand and this is the project for second of ESO this year, under

23
00:03:56,860 --> 00:03:57,860
this oil.

24
00:03:57,860 --> 00:04:06,800
I hope you can enjoy it.
