Caja Verde Pt. II
Grado 4º y Grado 5º
Nota: Para la Evaluación, deben estudiar solamente hasta el video de CONDUCTIVIDAD. Lo que está después del video no hay que estudiarlo.
Este Link:
·MBlock:
Programming Software: It allows instructions to be created for the HaloCode to execute.
·Alligator Clips:
They allow external devices to be connected to the HaloCode.
·Photocell:
It detects changes in light in the environment and relays that information to the HaloCode.
·Potentiometer:
It detects changes in the position of an object and relays that information to the HaloCode.
·Buzzer:
It emits sounds. You can connect it to the HaloCode and activate it using programming.
·Servomotor:
It changes the angles of external objects. You can connect it to the HaloCode and control it using programming.
·Cables:
They allow external devices to be connected to the HaloCode.

De aquí en adelante NO hay que estudiar, ya que los niños no tienen la caja
Taller Pendiente de la clase psada - Challenge #2
Programar Con el Teclado cada Led de 1 a 9
Create a program so that when you press a number on the keyboard, the corresponding LED light lights up.
1 key: the first LED light lights up.
2 key: the second LED light lights up.
3 key: the third LED light lights up.
4 key: the fourth LED light lights up.
5 key: the fifth LED light lights up.
6 key: the sixth LED light lights up.
7 key: the seventh LED light lights up.
8 key: the eighth LED light lights up.
9 key: the ninth LED light lights up.

Electrical Conductivity
Is the capacity of a material to transport electricity. For example, a soda can is a good conductor of electricity, whereas a ceramic mug is a poor conductor. It is the capacity of materials to transmit electricity. There are good conductors such as water, metal, and the human body. There are also poor conductors such as wood and plastic.
We can find the conductivity value of an object thanks to the touch sensor - touch value block, also known as touchpad - touch value.
The closer the number is to 100, the more conductive the material is. The closer it is to 0, the less conductive the object is.
For example, a metal pencil sharpener has a conductivity value of 99, while an eraser has a value of 12.
We will keep experimenting with the concept of conductivity using the HaloCode and mBlock.
We Will also create a program to turn on the LED lights on the HaloCode according to the conductivity of four different objects. The difference between the objects can be expressed as follows:
•Object 1 turns on LED lights 1 to 3.
•Object 2 turns on LED lights 4 to 6.
•Object 3 turns on LED lights 7 to 9.
•Object 4 turns on LED lights 10 to 12.
In a future we can match the color of the LED lights to the color of the object. For example, a banana with the yellow LED lights or an apple with the red lights.
Now we will use our fingers:
Workshop Challenge
•We will load the program Conductivity_Test.mBlock in HaloCode 3 and install an "alligator" wire in touch input 0 of each of them, with the other end making contact with one of the elements mentioned: plastic, metal and a glass of water. •The program uploaded to the HaloCode card will work as follows. When the touch input is not active (that the element that is touched by the hand is not conductive) the RGB led lights will emit the red color; when the touch input is active (that the element that is touched by the hand is conductive) the RGB led lights will emit the green color. Finally, students will be able to do the test with each element; In the case of the glass of water, they must dip a finger in the water to activate the input. •This activity will allow us to recognize the concept of conductivity and conductive circuit, which are needed for the development of interactive video game controls.

Prueba de Sonido
Challenge #
instalaremos un cable “caimán” en la entrada táctil 0 de cada una de ellas, y el otro extremo haciendo contacto con uno de los elementos que se mencionan a continuación. Luego los estudiantes utilizarán los siguientes elementos de diferente material: plástico, metal y un vaso con agua.
Cuando la entrada táctil no esté activa (que el elemento que se toca con la mano no sea conductor) las luces led RGB emitirán el color rojo; cuando la entrada táctil esté activa (que el elemento que se toca con la mano sea conductor) las luces led RGB emitirán el color verde. Finalmente, los estudiantes podrán hacer la prueba con cada elemento; para el caso del vaso con agua, deben sumergir un dedo en el agua para accionar la entrada.
Esta actividad les permitirá reconoce el concepto de conductividad y de circuito conductivo, los cuales se necesitan para el desarrollo de los controles de videojuegos interactivos.
