Thank you so much for this amazing video. I’ve been looking for exactly this to show my son how the gears & drive shafts work. Really appreciate you teaching us. Thank you.
Hello Gunnar, really explained very well. It's nice that you explain the physics behind it. As a teacher, I will integrate your videos into my school lessons. It's the best thing I could find on RU-vid about the Microbit. Grüße aus Stuttgart, Dirk
That is amazing. Thanks very much for sharing this. Would it be too much to ask if you would have the Lego parts numbers or code parts? Many thanks in advance.
Thank you very much for your comment 🙂 The Lego Mindstorms Education 9797 is no longer available so it would be an idea with the part numbers. I'm sorry that I can't give you the numbers - I have no longer the Mindstorm set. You could have a look at this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-9L3pASCBQxA.html where there is an other car made of Lego-like parts.
@@gunnarlund6633 That is great. Thanks so much to pass this over. I can get now the pieces online. I have watched some of your videos and they are very helpful. Once again, many thanks for sharing this.
Why is the value of 300 used in the following line of code? 'if (Read == 0 && pins.analogReadPin(AnalogPin.P0) > 300)' How does 300 relate to the analog value of the sensor? I guess what I'm asking is, what is the 300 referring to (time? light sensitivity? etc)? Thank you.
It refers to how much of the infrared light there is reflected from the object passing bye. The value is found by help of experiments. The highest value that P0 can have is 1023.
I don't think that the Micro:bit can handle a voltage of more than 3 V - and may be you will ruin it. If you have two resistors of the same value, you can connect them in series and to the voltage. Then you can measure the voltage over one of them with the Micro:bit and multiply the result by two.
@@jurrevanderwerff3800 Try with something between 1 k ohm and 10 k ohm. We are talking about a voltage divider - which you can learn more about by help of Google.
hi please can you help me to listen to my mp3 file using my mp3 player with my microbit v2 speaker .for the extern speaker connected to my mp3 player it's ok i listen to my mp3 file but now i want to listen with the integrated microbit speaker help please thx in advance kind regards
@@gunnarlund6633 i find a solution that i connect my mp3 player with a mini humberguer speaker but i´m eager to find a solution to listen my mp3 file with microbit speaker
It depends on your home country, but try: shop.elecfreaks.com/ An English version of this video can be found here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-jm00AW5sY4Q.html
Thank you Gunnar - lovely video and well presented. This will help with my daughter's school project. I did have to take a moment's silence for the poor lemon though... :-) Cheers from Sydney - Dave
Takk for videoen! Er der en måde du kan gøre det samme med et hundehalsbånd, der registrerer gøen og reagerer med en ultralyd for at forsøge at forhindre hunden i at gø?
Tak for din hilsen. Micro:bit version 2 har en indbygget mikrofon, som vil kunne registrere hundens gøen. Men den vil jo også kunne registrere andre former for lyd, hvis de er høje eller tæt på. Man kunne godt lave et program, der udsender ultralyd, når mikrofonen modtager en høj lyd. Den transducer, jeg har brugt, kører med 39 kHz, og så vidt jeg kan se, er den en frekvens, som hunde kan høre. Husk at der også skal være et batteri tilsluttet Micro:bitten.
I am a teacher in brazil, you are an inspiration to all of us, i love your classes on micro bit, i am sure your channel will increase much more, i live in a region of Brazil ( Rio Grande do Sul ) where most of the population speaks fluent German but I only understand English, congratulations for the professor channel, if one day you come to know Brazil you will be very welcome to visit my school we have German and English teachers.
Thank you very much for your lovely greeting, I made me very happy - and it gives me more energy, to continue. A trip to Brazil could be nice - right now it's cold and windy in Denmark.
Unfortunately, the extension "Devices" can no longer be downloaded from MakeCode. But you get it by downloading the program that I link to in the description.
Udvidelsen "Devices" kan desværre ikke længere hentes fra MakeCode. Men du får fat i udvidelsen ved at hente det program, som jeg linker til i beskrivelsen.
Hi Sally. Maybe you can get an idea from this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fh9yXPU-QF8.html You don't need to use the Wappsto:bit
Hej Gunnar, Tak for nogle meget motiverende programmer, som gjorde en stor forskel i min folkeskoletid 1996-2004. Jeg er lærer, og de programmer vi har nu, når dem ikke til sokkeholderne! Er det muligt, at du også vil dele dem med mig? Venligst, Kenneth Ps: Jeg troede jeg havde sendt en kommentar, men den kan ikke ses her, så.. måske du får den anden gang nu. I så fald beklager jeg.
@@Javvy9 If you click on the program-link the program will be opened in your browser. Click "Edit" and you will be able to modify it. Connect the Micro:bit to your computer by help of a USB-cable and choose "Download". Choose "pairing" if you are asked about it. Then the program will be transfered to the Micro:bit.
@@gunnarlund6633 thank you very much sir I appreciate your humbleness I am making this project and please help me if I further need your help although thank you for your support.
@@gunnarlund6633 sir I wanted to discuss how can I program it in a way that in the first micro bit it could count till 9 n in the second three points get reduce by the touches the limit should b 3?can you please help me
Hi Gunnar Lund my school has bought a load of these sensors but none of them seem to work.They either don't detect any motion or detect motion every second. I was wondering if you would have a solution, thanks
Hi Sulantro. It takes some minutes until the PIR has warmed up! Do you use an external power supply? 3V from the Micro:bit is not enough. Do you connect as well the PIR as the Micro:bit to common GND? Have you studied my video where the adjustments are explained? Are the of the same type as shown on the video?
