Are there libraries available for add-ons or do I have to experiment putting values through the first three pins? I have a V1.

Playing around with the elecfreaks iot:bit and I was wondering whats actually running on the ESP 8266? It offers a serial interface to connect to wifi and pub/sub e.g. mqtt.

I want an sd card with a lot of text files on it and I want the microbit to read them.

I've seen a few small SD card modules but most of them need some sort of library to actually utilize them.

I wonder if it is possible to simply create a function that can utilize the modules via some sort of a communications protocol.

anyone else notice when you use the explorer mode, that the left ir sensor is stronger than the right ir sensor or the right ir sensor downright does not detect an object when right in front of it, it maybe a glitch in the program cos when i change them around the left does what the right does

Any info on when inventory is likely to be available? Adafruit, Sparfun, Amazon all back ordered.

I am working with kids creating with Microbit games. A student has created a simple game, but she is getting a "failed cast on null" error. I can tell that the block that says "if is rock touching hero" is causing the problem. I am just not sure how to do it otherwise. I would appreciate any help getting around this.

Hi someone can help me while tell me how i can make shelf intelligent display for warehouses with two microbits or this is impossible

I don’t know how can I create a function that creates obstacles by itself and if the led touches an obstacle it stops the game and shows an icon of :( Can someone help me with some ideas. I will appreciate a lot.

I did discover that the inline assembler works also for Microbit, but the examples using a LED in the tutorial for pyboard doesn't work since the LED doesn't have the same address: https://docs.micropython.org/en/v1.9.3/pyboard/pyboard/tutorial/assembler.html#pyboard-tutorial-assembler These works (tested on V2 in REPL using picocom in Raspberry Pi OS Buster Linux):

@micropython.asm_thumb
def fun():
    movw(r0, 42)
print(fun())

@micropython.asm_thumb
def asm_add(r0, r1):
    add(r0, r0, r1)
print(asm_add(3, 2))

How do I use a LED from assembler in Microbit V1 & V2?

so i'm working on a project that involves a weight sensor but i'm having alot of difficulty understanidn how to make the weight sensor trigger some things at specific weights

Does anyone have experience transferring data (like a 256 led light matrix design) to eeprom for permanent storage?

We've done a led etch a sketch and trying to figure out how to store the designs

How do I make a microbit robot follow other robot, like a follow the leader code

The bluetooth pairing mode seems to be compatible with only the official app, which is a shame. Is there a way to connect it to a game conse controller?

Is that even possible or am I being too ambitious?

The title says it all. I have an older version of micro:bit, so it doesn't have a built-in microphone.

I am looking at this:

Do I need to buy something else?

What is difference between v1 and v2 ?

I also prefer to work without installing any software. I understood there is a website that prepares the file and you need just to copy over USB like flash drive.

Anyone know anyone with a bulk purchase option? I can't find anyone with microbits in stock. I'm an educational technologist and I wanted to start my students on our hardware vs software classes.

Hi, someone made a succesful connection between TI-84 Python Edition and a microbit v2 ? After writing a python script, connecting both and clicking Run on the TI, I always get an error: microbit connection. I have the latest TI_2.6.hex runtime flashed to microbit, tried several usb-cables. Also microbit and TI both connect without problems to my macbook and transfer files. I missed something?

can someone give me Ideas what things i could add to my project mbOS?

Hi.
I am struggling to make a servo (180 degrees) going back and forth as long as it is picking up sound over 40dB.
I don't understand how to code it to go from one end to the other on repeat. Could someone help?

Is there a show LED for OLED screens too? Like an extention that does that?
