M3 length 12mm

Hey, i think there is like a million other arduino cars with yellow dc motors on youtube so i would search for something elese.

Check the website

All materials are in the description. I don know what you mean by wire? Robot is controlled by bbc micro:bit.

:-)

Hey Julius. I use M3 Nuts and bolts with mainly 12mm bolts with cylinder head

I did, check the website

Yes

Thx Mate. It must be simething in your computer. I am pretty sure there is nothing wrong with the code

@ thanks very much!

Hey, there was a bug in price geolocation plugin on the website. Thank you for pointing this out! Please email me for a discount code if you are interested in the getting it in this lower price.

Thank you! Cheers!

Yoy mean that you can upload my hex file but cannot upload code from makecode?

@CARDBOARD_ROBOTS written a same but using a another Bluetooth extension

Other bluetooth extension in MakeCode? I dont know any..

@@CARDBOARD_ROBOTS ok but using your extension working fine and code upload easy

Hey, all info is in the project page

Hey there!

Thank you! Cheers!

Hey Gab. I updated project page with basic code. cardboard.lofirobot.com/led-puppet/

Yep, if it you can connect 3 micro servos to it. Some chassis dimensions adjustments might be needed as well.

I actually have it almost ready, with three robot types. Even the videos are recorded BUT I am not releasing it because I want to put out one other thing first - a new mini app with Teachable Machine to Micro:bit interface - i use it in this project to detect color of ping pong balls.... so I dont know quite when...

Look at this video ruclips.net/video/XbQz_ME1SbI/видео.html

It depends how do you connectit. If you want to draw rhe oower from the microbit, then it will work but only ine servo and it will be very weak. If you have some adapter then it provides the power for rhe servis and they should work fine as long as they are compatible with 3.3v signal

@@CARDBOARD_ROBOTS For my part I want to provide power through the breadboard with a 9 volt battery but I don't know if I need a resistor or something else to make it work, and if so what kind of resistor I would have to use.

In general, when you power a motor you do not limit it with a resistor. But 9v is a bit too much for a micro servo, most of them operate at 6v max

Also be careful with 9v around the micro:bit you might fry the io pins when you mess something on the breadboard

I would better go with 3 or 4 AA or AAA batteries

Hey, if you do breadboarding maybe check Arduino version of this robot: ruclips.net/video/wF3MR8pRAGo/видео.html

But yes,if you have breadboard adapter for the micro:bit it will do as well. As long as you will know how to connect the servos an power them.

@@CARDBOARD_ROBOTS Thank you very much, I will take this into account, although I would have to see some tutorials on the protoboard, thank you very much

It is 360 degrees micro servo motor, it has to be 3,3V compatible

@@CARDBOARD_ROBOTS ok thanks

There are two type of servos 180deg and 360deg. You need the latter one. Also most of 180deg servos are 3.3v compatible and work with microbit but a lot of 360deh serovs is not 3.3v compatible and will not react to mb signals (even if tou power the servo with 5v, the signal line from mb is 3,3v)

Hey! Interesting concept. Please write some example use cases??

@@CARDBOARD_ROBOTS Micro.bit itself has some sensor, we can use those sensors to feedback environment data.

This i understand. But to design interface for this data it would be good to start with some use cases what we want to do with them. Maybe you have some idea for a project, if i know it then it is easier to incoroporate it into the app

I mean there are several options to do is. Rhat is why i ask questions why do you need it?

@@CARDBOARD_ROBOTS I don't know what I want but I just want to share with you my code. async function receiveUART() { try { // Start notifications for the RX characteristic to receive data await rxCharacteristic.startNotifications(); console.log("Listening for incoming data..."); // Add an event listener to handle incoming data rxCharacteristic.addEventListener("characteristicvaluechanged", onRxCharacteristicValueChanged); } catch (error) { console.error('Error starting notifications:', error); } } function onRxCharacteristicValueChanged(event) { let receivedData = []; for (var i = 0; i < event.target.value.byteLength; i++) { receivedData[i] = event.target.value.getUint8(i); } const receivedString = String.fromCharCode.apply(null, receivedData); console.log("Received:", receivedString); }
