Hand dryer 乾手機 @STEM II with 12 models

Hand dryer:  you certainly won't have anything like this in your bathroom at home, there you have a towel hanging on a hook. But in public toilets or the restrooms in restaurants there is usually an electric blower mounted on the wall for blowing your hands dry with hot air.

A good invention, particularly when the state-of-the-art appliance doesn't even have a button you have to push to turn it on.  Simply hold your hands beneath it to turn it on.

Part 1 - micro:bit block commands used in the Hand Dryer 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 Hand Dryer  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 model (12 of them), you can learn, practise, build fluency and confidence in coding.

The Hand Dryer  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:
