We studied the transistor. Today, in order to understand how it works, we are going to create a circuit in Tinkercad that includes a transistor capable of giving way to a current, when another one is provided by the middle pin.
Mosfet or as we all know, switch; it is an electrically operated switch that allows a current flow, it is made of silicon.
These devices can act as a switch without moving parts, and their main function is amplification.
Doping is used to improve the conductivity of semiconductors.
HERE ARE SOME PICTURES THAT EXPLAIN A LITTLE BIT:
This are two links of two videos that explains better the functions of a TRANSISTOR:
Today we are going to show you how to make an app with the free software app inventor that will serve us as an audio guide to recognize in which containers we should deposit the waste.
We will use:
Buttons
Images to cover the buttons
The TexToSpeech resource
The design will be as follows:
The programming blocks for the operation of the app are:
Video of how was developed:
We test the app:
Now, I'm going to show you how to record a video from your mobile screen and then upload it to Youtube. For example to make a video like the one above:
These are the steps:
Some mobile devices have the predefined function to record the screen, in case you don't have it you should download a playStore app, there are many, I do well with AZ Recorder.
When you have downloaded it, to record your screen you must enter the app and then press the button on the camera, in 3 seconds it will start recording. It is a very simple app.
To end the video you must press the stop button, automatically the video will be saved in the gallery.
To upload it to Youtube, you must go to the gallery, press the send button, look for the Youtube icon and press it.
You will have to include a title and a description and then send it.
If you do not have a Youtube channel yet, you will be asked for the name you want to give to your channel.
The video will automatically be uploaded.
Both in the Youtube app of your mobile, and in the computer by entering www.youtube.com , you can manage the permissions of the video, change the title, delete it, etc.
THIS VIDEO IS ABOUT A SPANISH DIITAL COMPANY,IS A GOOD VIDEO AND YO CAN LEARN A LOT OF IT.
If you are interested in knowing a little more or just imagine how life can be in the future, this video will enlarge several images about a better future and may clarify ideas for you. Not only does it talk about change about society or simply about technology, it also shows you an idea about the world economy, it gives very broad images and I think this video is quite good. Rather, it makes 4 references so that you have an idea of how the world can be in the future, specifically speaking in 2030, 10 years from now, since things are still changing and increasing.
Como es complicado incluyo los pasos por escrito en castellano:
Buscamos una retrato con fondo muy blanco, la guardamos con el nombre “original”.
Abrimos GIMP y buscamos el archivo de nuestro retrato.
Para cambiar el tamaño de una foto → Imagen → Escalar (la dejamos en un tamaño de unos 400/600 px
Si no nos aparecen las barra de capas a la derecha: Ventanas → Diálogos empotrables → Capas
Duplicar la capa original y la nombramos como B y N
Ahora vamos a dejarla en blanco y negro con la pestaña colores → Umbral (movemos para dejarlo en un punto que se reconozca bien el retrato)
Creamos tres nuevas capas transparentes con botón derecho capa nueva, (aseguraros que pone “transparencia”) las llamamos capa1, capa2 y capa3
En la capa B y N, seleccionamos por color toda la parte negra.
Vamos a la capa transparente 1 -> Editar → Rellenar con el color de frente → Se llenará con el color que tengamos predefinido, Cambiamos el color predefinido a morado y repetimos el proceso .
En la foto “original” nos vamos a la barita mágica (si no aparece herramientas → Herramientas de selección → Selección difusa). Seleccionamos el fondo (cambiamos el umbral para que se ajuste bien al rostro del retrato).
Seleccionar → Invertir, así se selecciona la cara., en vez del fondo.
Nos vamos a la capa color 2, y seleccionamos el color frontal amarillo. Entonces vamos a Editar → Rellenar con el color de frente.
La última capa transparente 3, la seleccionamos toda. Luego seleccionamos el color frontal rojo. Entonces vamos a Editar → Rellenar con el color de frente por completo.
Archivo → Guardar proyecto → Foto Warhol
Archivo → Exportar como → Susana1Repetimos el proceso con 4 fotos y montamos el mural
