MicroSoft makecode


Step 1

Click "Advanced" in the drawer of MakeCode to see more choices.

For programming, we need to add a package. Click "Extensions" at the bottom of the drawer and then search "Wukong" in the dialogue box to download it.

Note: If you get a warning indicating some packages will be removed because of incompatibility issues, you can follow the prompts or create a new project in the menu.

Step 2

Click Wukong to choose mecanum block.

Step 3

Drag mecanum into on start block and set the connection for servos accordingly, then initialize the LEDs.

Step 4

Set the variable L and R to a random number between 0~100 and judge their numerical value. If the value of R is more than that of the L, set LED as 0 in black and 1 in yellow; or set LED as 1 in black and 0 in yellow. Then refresh the LED. Next step is to assign the value of variable L to the speed of the front&rear wheels on the left side and the value of variable R to the speed of the front&rear wheels on the right side, and pause 2000 ms.
