Merry-Go-Round 旋轉木馬 @STEM II 12 models

single micro:bit model from pack

fischertechnik

Product Description

 

You can find various models of merry-go-rounds at public festivals and amusement parks. The first motor driven merry-go-round was placed in operation on January 1, 1863 in Bolton in England.

 

Task 1

The merry-go-round is to be started with the push-button switch . It is to rotate for 10 seconds and then stop.

Task 2

Just going in one direction is rather boring. Change the program so that it waits a second after the motor stops and then the merry-go-round turns in the other direction for 10 seconds.

 

See full online guide with micro:bit coding samples for the Merry-Go-Round model , plus extension activities.

Part 1 - micro:bit block commands used in the Merry-Go-Round Model

To achieve fluency and competency in micro:bit coding, you really need to get a thorough understanding of each of the block catagories to be used in the Merry-Go-Round Model (see part 2 below for the full code).    Fortunately, all the reference guides are available on the BBC micro:bit web site for you to get a deeper and more comprehensive understanding and mastery.

Through every fischertechnik STEM II models (12 of them), you can learn, practise, build fluency and confidence in coding.

The Merry-Go-Round Model used the following micro:bit blocks.  You can click to lean more about each of the block catagories.  The links bring you directly to the respective part of the BBC micro:bit reference document site, where live codes are included for you to understand, try, and download:
