single micro:bit model from pack


Pedestrian light 行人過路燈 @STEM II 12 models
Product Description


You certainly have seen various models of traffic lights. You encounter pedestrian lights or entire intersection systems almost daily so that the principle is not anything new for you.

Stated simply, lights are turned on and off in a certain sequence.  


Task 1

Program a pedestrian light, which is switched with a push-button switch. At first, the light is red. When the push-button switch is pressed, the red phase is to continue for five seconds. This is to be replaced by a green phase, which lasts for 10 seconds. After this, the light returns to red.


Task 2

As in task 1, program a pedestrian light, which is operated with a push-button switch. After the green phase is ended, the green light is to blink to show that the pedestrian light will change to the red phase in a short time. The green light is to blink three times.


Task 3  

(requires 2 sets of this model pack)
Build 2 sets of the lights - one for Pedestrian and one for vehicles.  Can you get them to sync and count down as seen in many traffic inter-junctions?

See full online guide with micro:bit coding samples for the Pedestrian Light model , plus extension activities.

This is a specially discounted package - delivered in a clear plastic bag.  

Each pack comes with the bonus fischertechik storage base (box 250 x 186


I/O board for micro:bit 

micro:bit pins extension board, designed specially to take advantage of  fischertechnik's unique,  flexible red and green round plug cable connections. By design, the I/O board rubber legs slot into the fischertechnik black base-plate grid securely.




The price below is for 1 model out of the 12 models STEM II pack.  If you want to build all 12 models, order the full STEM II pack instead.


  • 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 Pedestrian Light 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 Pedestrian Light 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 Pedestrian Light 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:



Part 2   The "live" Pedestrian Light Code (Task 2)  - Understand, Edit and Download

  The following code has used all the mentioned blocks in Part 1 above.    


1.    In English, click the " ? " on block to find out the meaning of the block code.

  • If you read this page on a computer with wider screen size, you will be able to see the micro:bit simulator that is fully clickable.
  • If you cannot see the code, such as on a mobile phone, please  click this link instead.
  • Click   to open the code on the micro:bit website for further editing and modification.
  • Click   to download this code to your micro:bit for immediate use or to save on your computer.
