This is an Online Lesson, Briefly discuss the Microcontorller in general but focuses on the use of Arduino. besides, the kids will be introduced to the LED ( Light Emitting Diode ) in general and use it to build some applications like ( Blinking LED, Fading LED, and traffic light ( LEDS, and RGB LED ).
However, you don’t need to buy any physical component as long as this workshop is Online Which uses :
– Arduino Microcontroller ( digital component )
– TinkerCAD ( Open source platform “free” )
TinkerCAD Account ( Free )
Here we just want to break the ice so the kids can interact and tell their opinion. Also, we want to build a connection between what students know about computers to be reflected in the microcontrollers level.
1- Try to give a brief about the computer such as ( the computer is a device process data according to our instructions ).
2- Don’t go deeper and try to give examples ( Laptops, calculators, Smartphones, etc…. )
3- If you feel that they are interacting and starving for more try to ask if any one knows the computer language ( Binary system “0,1”).
**Note :”In this Lesson we have two parts ( Theoretical and Practical ), the theoretical part should take 15 Minutes and the rest for the practical )”
Here we want to briefly explain how the computer interacts with the environment especially us ( humans ); however, we are not expressing widely just mentioning the human senses and how it's similar to computer input devices. ( Real-life examples makes it much easier for them to understand).
1- Don’t go deeper just stay straight forward ask them about the human senses and you connect these senses with the input devices ( Eyes >>> Camera , Ears >>> Microphone) you can also mention output devices ( Mouth >>> Speaker )
2- If they are interacting you can mention that each computer have a brain like ours to process data.
3- The introduction should not take more than 5 min but it helps to attract their attention.
In this section, we are going to briefly describe what is meant by LED in addition to the physical specification of this component and how to connect it in the circuit.
1- The first step to tell the students what LED refers to ( Light Emitting Diode ) a device that when it recives power it starts to emit light.
2- The physical looking of this component; so this component concist of two legs to be connected with battery one of them is longer than the other which is connected to the positive side and the other one goes with the negative side.
3- Its not necessary to mention eample try to ask them to bring some .
This section talks about the RGB LED which we are not going to go in detail.
1- We are going here to mention what does RGB Refers to without any turnning to details.
2- Its enough to mention the way this component works by mixing colors to make a new one and this componnent can produce more than 16 million hues of light.
In this section, we will try to connect all the information above together so they can understand how these strips are built and how they work.
