Chapter3 :숨쉬는 불빛을 만들어 보자¶
1.Preparation¶
1.You should learn about the position of the colorful lights in the body of hellobot；
2.You should learn about the micro:bit pins connected to the colorful lights in the schematic.
1-3-1 colorful lights on body of hellobot（back）
1-3-2 colorful lights on body of hellobot
We can make different colors of light and brightness by programming.
1-3-3 schematic
1-3-4 Pins of Micro:bit
From the schematic diagram in P1-3-3, you can see that the colorful lights is connected to the P16 of the Micro:bit.
Note:In the bottom layer of the HelloBot package has been set parameter for the user, you can directly drag the colorful lights building blocks.
- Learning goals
In this course, we learns the new game of colorful lamps - breathing lights. Breathing light: the colorful lamps are changed gradually from light to dark by the control of the micro:bit. It feels like a person is breathing.
3.Programming
3.1 Programming online
1) You should use the USB cable to connect the micro:bit to the computer, at this point, the computer will have a micro:bit U disk. You need to open it, click micro:bit website, then entered the micro:bit website or you can enter the URL directly in your browser: http://microbit.org/
2) After entering the programming interface, you need to click Add package and copy the HelloBot package URL: https://github.com/lzty634158/HelloBot to the input field, click to confirm the add package. Then you can use the blocks of the HelloBot package.
3.2 Programming offline
- You can double-click to use it. As shown in the following figure.
2) After entering the programming interface, you need to click Add package and copy the HelloBot package URL: https://github.com/lzty634158/HelloBot to the input field, click to confirm the add package. Then you can use the blocks of the HelloBot package.
Note: The package only needs to be added once. If you have added packages in the previous lessons, this course does not need to be added repeatedly.
