Lighthouse 燈塔 @STEM II 12 models

single micro:bit model from pack

fischertechnik

Product Description

 

Lighthouses stand at important or dangerous points where they serve ships as a navigation mark, which is visible at long distances including at night.

With their light signals (beacon), lighthouses show ships the way and thus allow navigation and the bypassing of dangerous positions in the waters.

In the nautical charts, the characteristics of a beacon are described by uniform abbreviations, for example:

 Intermittent light The phases of light and dark are of equal length.  
Flash 

The light phases are shorter than the dark phases.  A flash lasts for less than two seconds.

Blinking light

The light phases are shorter than the dark phase. An blinking light is at least two seconds long.

 

Task 1

Program a "beacon" according to the isophase principle.  Set the light and dark phases to be of an equal length of two seconds.

Task 2

Program "lighthouse lighting" according to the flash principle.  For the flash lighting, set the light phase at 0.3 seconds and the dark phase at 1.5 seconds.

 

Task 3 Program "lighthouse lighting" according to the blink principle.  Both lights are to be illuminated for a different period of time independent of each other.

  • All model parts can be reused and recycled for other projects and student's creative pieces.    fischertechnik is made in Germany with quality and precision.
  • No soldering.  Ideal for all ages, promote problem solving, changes on the fly as debugging and adjustment can be done instantly.    All works can be done to perfection as even the smallest adjustment can be accommodated, thanks to the complete range of mechanical/structural and electronic blocks offered by fischertechnik.
  • One of the 12 models of STEM 2.   You can now order it on its own for easy whole class lesson, without needing to pick and sort building blocks every time.  

 

Part 1 - micro:bit block commands used in the Lighthouse 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 Lighthouse 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 Lighthouse 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:
