fischertechnik and BBC micro:bit
Barriers are located in front of many parking lots or parking buildings. They open when a car drives up and close again after the car drives through. Have you ever wondered how the barrier knows when a car is standing in front of it and it needs to open?
Build the model using the assembly instructions and connect the cables according to the circuit diagram.
Please try the suggested task below.
At the beginning the barrier should be closed. Then when the light barrier is interrupted, the arm moves up. After 3 seconds it should close again.
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 Barrier 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 Barrier 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:
The following code has used all the mentioned blocks in Part 1 above.
Comments In English, click the " ? " on block to find out the comment (meaning) of the block code.
