This my first printer. I got it on Monday afternoon (today is Wed.) and printed several pre- coded files on the included micro SD card. Now I am getting new files from Thingiverse. The printer is said to be for classroom use and we can use it that way for sure. I made a Microbit driven fan to cool the print as it is making. We are very happy with this printer; super simple and the newest version has been well de-bugged. Thanks as always for your comment.

This is an interesting point. I have re-watched this video and believe that my comments on MakeCode are valid. When making videos I often have 3 browsers open and many tabs on each one open. We now have failed downloads for many MakeCode programs at the library and coffee shop; this is happening ever more often. I have NOT seen notes from Microsoft that we must close all other browsers and all other pages before attempting to download to hardware but suspect (there's no reason not to) that there is firmware interference if all these other tabs and browsers are open. This may be an issue that should be acknowledged by Microsoft and / or fixed by them. They should at least make consumers aware of the issue. (Kind of like: Your bus won't start if the headlights are turned on. You should be told that by someone.) So I'll leave the video up. If Kittenbot want to inform users of DuckyBot how to turn off RGB LED in Jacdac then I'd like to see them do it. Or, they may just be shipping the module with updated firmware. Thanks for the comment.

@@makecodeandhardware1395 my suggestion in no way was meant to suggest your views were invalid! Sorry if I gave that impression. I am not sure about the multiple tab problem ( not really a problem more a byproduct of how browsers & microcontroller connect to each other) can be " solved" but you are absolutely correct that the issue should be acknowledged & people told about it significantly more than they current are doing !

We have had Maqueens for over 5 years. The Cutebot Pro is the first Elecfreaks product that I have bought. Thanks to your questions I am discovering its capabilities. I see that Cutebot is used as a platform for public education robotics in the new CODERS program sponsored by Missouri State Univ. for rural schools (as opposed to VEX, LEGO EV3 or Pitsco edu. robots) which prompted me to buy one with a donation from a local retired pharmacist. We will learn more about the Cutebot. Thanks for the comments !

I have not tested them , Don. Will do that this week. If I read your question correctly; "Does this follow a grey line on white in addition to following a black line on white ? " Watch this channel for the test project.

@@makecodeandhardware1395 actually will the ir sensors return the reflected amount (0 to 1024) instead of just 1 or 0. Maqueen Plus V2 will do that. Which means PID control can be used.

@@jdonwells You may have already seen this program; Don. I see in the Cutebot Pro extension a reference to gray value under 'tracking sensor' so to me this implies that with MB V2 that may be possible, PID control. I have not got that far with the new Cutebot Pro car. We are focused on remote control with BST M_Bit app and donated cell phones. Thanks for the input. Very interesting question. tinyurl.com/3fcd23h5

@@jdonwells , see my latest video, Don; for the answer. (spoiler : YES 0-255 ) But I don't know about PID control.

@@makecodeandhardware1395 I have a slide show to explain PID control. docs.google.com/presentation/d/1QdxlaT2WuEbwisWb3d1CxsuiMVr19kL6_wUgoftC0sw/edit?usp=sharing PID is something engineers actually use. It is an advanced topic. I teach at a high school so I like to push the kids.

That would be great to see. Do you watch this guy on UA-cam ? isogawa yoshihito : great channel for being a "maker" with LEGO Technic. www.youtube.com/@ISOGAWAYoshihito/videos

Our friend, Jason Davies visited us here in Missouri, USA ; from England, and he programmed these cameras with Arduino so the firmware now works with WiFi built in. I left the programming "hat" on the camera board because that has the micro-USB plug for power input. You can also just use one hat for many boards to program them and then plug battery direct into pins on the camera without the board. You must have a browser installed on the mobile device; or laptop. I find that Safari sometimes does not work on iPhone. But, Edge and Chrome always work for me with this camera. Thanks, as always, for the comment.

I like the encoder motors ! I am looking for any other bot car in this price range that has encoder wheel motors; I don't find any as yet. I think Cutebot Pro is expected to expand functions to add camera and machine learning (like the DF Robot Maqueen Mechanical) ; so maybe we can build out really smart cars. Cutebot Pro is designed for LEGO Technic beams and axels which snap together ; Maqueen structural parts must be bolted on. I think this will help a lot to snap together with no screw driver or pliers needed. Plus, Elecfreaks has great tutorials and study documentation for learning how the car works.

Trying to use all tab screens on the cell phone app she tries to find which A-Z command relates to which icon that she presses. She tries to 'discover' which lines of code apply to which 'keys' that she presses on which window on the screen. The app has many options the way it creates the phone screen choices and in the code it looks like many 'send signals ' beyond A-Z , like 1,2,3 .

I think they do range from 0-255. It is difficult to know because the colors displayed are not correct; 255 in the red bubble and 0 and 0 in green and blue does not give red. I have tried all three different RGB type options in setting the system on start.

@@makecodeandhardware1395 maybe try a different colourbit type device ? What about the 8*8 I saw in previous video ?

@@Keeping_IT_Simple I'm not trying to resolve the problem, just making an observation. See my next video for the next project.

Thank you for your nice comment. We watch your channel also, thank you for your projects too !

Thanks for the nice comment, Matx25, I hope you are well and happy.

We are well and busy with school and work, unfortunately not much time for new electronic/Microbit projects.

@oldhorn420 . It was because of the help you gave me from your steering video. My assembly is different but it uses your basic ideas. Thank you for your help ! !

You are welcome ; we learn all this together so that makes UA-cam very useful. Now we have learned that LEGO bricks work so well with Technic parts so Motors on Bricks can activate LEGO projects along with all these sensors that fit together.

This system has no code. Jacdac is a Microsoft system using Kittenbot Jacadaptor and Kit B which has a motor board and a power board. The servo motor (positional or continuous) plugs into the motor board. When you turn on the switch of the battery power board then the motor shows up on the computer screen. Now you can swipe left or right and the motor turns if a Microbit V2 is plugged into the computer by USB. We have many videos about this. You can also add code in MakeCode.

@@makecodeandhardware1395 ahh get it, thanks dude!

@@makecodeandhardware1395 I also want to get my first red motors. Which yahboom kit should I get? I was trying to get the spider kit with the 2 red motors and the super:bit expansion board

Yes, I think the intention by the designers of the Sensor Kit is to make it more child friendly. I find RGB is NOT correct. The code suggests pins12,13,14 but there are only 2 data pins per connector, like 12 and 13. Also, 255 on red bubble of RGB series does not show red. Is it GRB ? I cannot make that work either. Much to learn.

@@makecodeandhardware1395 , I think you are right. There should 3 data pins for colour. I do not have time now to look up their data sheets. I suppose the 3rd bit is hidden somewhere - read carefully...

I am not a big fan of LEGO Bricks because this developed after I was a child. But they are very popular so we add motors to them to learn coding and electronics. I find most kids are very experienced with LEGO Bricks. Our local library has a monthly STEM session with Bricks for kids.

Have you used Bill Siever's 'date / time' extension in Make Code ? github.com/bsiever/microbit-pxt-timeanddate we have a video about it.

@@makecodeandhardware1395 , this is GREAT, thank you a lot - NO, I've never seen this extension, I actualy tried to do something similar to another microcontroller board (PICOED, rasberry-pi based - python accesed). Very clever stuff, indeed. THANKS!

Thanks for all your help, @Keeping_IT_Simple ! ! !

This is not an expensive kit set. DF Robot makes the voice recognition module. I attached it with Velcro to a clear plastic square. There are two Microbits : one for 'send' using voice commands and one Microbit on the DF Robot Micro Maqueen 2 wheel car. The I2C board is by Keyes Studio.

With just changing the code @loafers1014 , you can make it go faster by increasing the numbers in the bubbles for speed: Set all motor direction rotate forward to speed (80)....to speed (100). and the same with other speeds. This will make it go as fast as possible. But it might be a problem because the sensors might not be able to read the input (black line or white paper) fast enough and the bot car might go past the line edge if the wheels turn too fast. Try it and see. Sorry for my late reply.

@@makecodeandhardware1395 thank you so much!! This will help out a ton. Dont worry, you replied just on time

We learned that these gray and black wheels in VEX are called Omni Wheels and they do offer Mecanum wheels also. We bought these Omni Wheels on Alibaba with the X hubs for Lego Technics motors. We have now bolted them onto VEX wheel hubs and they are much, much cheaper than VEX brand Omni Wheels.

I think this happens sometimes. Try to work in a different browser, if using Chrome then try Edge or Brave. Or: Try "save" the program, not download. If it saves as a .hex file, in your downloads folder or other folder, then plug in the Microbit and drag the .hex file onto the Microbit drive. Also, when you save or download make sure to click "Done" if that is offered. I hope this helps. Tell me if you have more questions about it.
