1. Learning Objectives
In this course, we mainly learn how to use MakeCode graphical programming to make the Lifting platform automatically rise and fall.
2. Building Blocks
For the building block steps, please refer to the installation drawings of [Assembly Course]--[Lifting Platform] in the materials or the building block installation album.
3. Motor Wiring
Insert the building block servo wiring into the Super:bit expansion board S1 interface, and the servo orange wiring into the yellow pin of S1.
As shown in the figure below:
! Notes:
When taking the course related to the building block servo for the first time, we need to remove the gear on the servo and upload the program of this course to the micro:bit; then turn on the power switch of the Super:bit expansion board and wait for the building block servo to turn to the initial position; then, we can turn off the power, adjust the lifting platform to the lowest position, as shown in the figure below, and then install the servo gear. (If you have used the lifting platform and servo-related programs before, you can skip this step)
4. Programming
Method 1 Online Programming:
First, connect the micro:bit to the computer via a USB data cable, and the computer will pop up a U disk. Click the URL in the U disk: https://makecode.microbit.org/ to enter the programming interface. Then, add the Yahboom software package https://github.com/YahboomTechnology/SuperBitLibV2, and you can start programming.
Method 2 Offline programming:
Open the offline programming software MakeCode and enter the programming interface. Click [New] and add the Yahboom software package https://github.com/YahboomTechnology/SuperBitLibV2 to start programming.
4.1 Add expansion package

4.2 Building blocks used
The location of the building blocks required for this programming is shown in the figure below.
4.3 Combined blocks
The summary program is shown in the figure below.
You can also directly open the microbit-Automatic-Lift.hex file provided in this experiment and drag it into the browser that opens the URL, and the program diagram of this project source code will be automatically opened
5. Experimental phenomenon
After the program is downloaded successfully, the micro:bit dot matrix will display a heart. Turn on the power switch, the servo will initialize to 0° (Lifting platform descends). One second later, we can see an upward arrow pattern on the micro:bit dot matrix, the RGB light turns red, and the Lifting platform rises; 500 milliseconds later, we can see a downward arrow pattern on the micro:bit dot matrix, the RGB light turns green, and the Lifting platform descends. And keep looping in this state.
If you need to restart, press the reset button on the back of the micro:bit motherboard.
