In this lesson, we mainly learn how to control building block motor by micro:bit and Super:bit expansion board.
Mode 1 online programming: First, we need to connect the micro:bit to the computer by USB cable. The computer will pop up a USB flash drive and click on the URL in the USB flash drive: http://microbit.org/ to enter the programming interface. Add the Yahboom package https://github.com/lzty634158/SuperBit to program.
Mode 2 offline programming: We need to open the offline programming software. After the installation is complete, enter the programming interface, click【New Project】, add Yahboom package:
https://github.com/lzty634158/SuperBit, you can program.
3.Looking for blocks
The following is the location of the building blocks required for this programming.
4.Combine building block
The summary program is shown below:
Please refer to the assembly steps in the Assembly instructions folder for building blocks assembly steps.
As shown below,
Left motor connect to M1 interface of super:bit.
Right motor connect to M3 interface of super:bit.
5. Experimental phenomena
After the program is successfully downloaded, the micro:bit dot matrix will display the smile pattern and the car will advance with different speed, speed is 0 -> 125 -> 255 -> 125. The car will keep a loop in such a state.
If you need to start over, press the reset button on the back of the micro:bit board.
