So great that most French speak 40% of the sentences with English words! In 3034 it will be 100%

Great video 👍🏻

Thank you for this video. Very informative and enjoyable!! Subscribed

Hi Le Grille-Pain, Thank you for your very interesting video ! I'm currently working on a project requiring a perfect loop with a raspberry pi 4. I've done quite a few tests with Gstreamer, the result is better than with VLC, but there's still a micro-freeze and it doesn't accept 4K videos. So I tested your solution with openCV and thanks for your good work! However, I have a question: do you know how I could avoid storing the video in RAM? Because I only have 2GB in the raspberry pi, and I need more for a lot of my videos...

Thank you for all the investigation and testing

I bought an Arduino last week for the first time (after using the Raspberry Pi for decades). The Arduino is lots of fun. I have now a large collection of gizmos (modules) to plug into it, like a kid again discovering something new. I bought it though to tinker with some model railway projects, and discover that because they have changed the two main micro-controllers, the R4 is a different architecture to the R3 and is not compatible with a complex model railway control system that I wish to build. C'est la vie, not a disaster. I'll get the older Arduino Mega for the project, and keep the R4 Wifi for another project. Merci pour la vidéo, nice accent ;)

Would be nice if people that can. Could work on porting GRBL to the R4. Would be a wonderful 32bit drop in upgrade for arduino driven projects.

Merci ! I don't speak French ha ha . I wish I could understand your very fast English accent. Thanks goodness for the closed captions. I appreciate pointing out issues in the tutorials that can cause problems.

Please slow down! I understand English is not your first language, but your fast speech & accent are very difficult to follow. You have excellent content - just slow down!

Do you have info on why the SPI bus is slower on the R4 than the old R3?

We need a basically 328P refresh drop in chip from Atmel, still 5V, more memory, more ram, higher frequency, maybe better ADC, DAC etc... Uno need this, not that microcontroller from Renesas

this is very close to what I need for a project. Are you able to help me program something for a Raspberry Pi?

I had a lot of trouble with the performance of python-vlc (libvlc), and I need sound, so the solutions presented in this video are not applicable. What did work is controlling an HTML video via Javascript. Works smoothly in fullscreen, and there's plenty of guides for how to loop it. I recommend this avenue if you need sound.

Unfortunately it is NOT backward compatible. Should have been called duno.

The lack of a crystal has rendered the R4 not useable for my turntable projects that are driven by SimpleFOC. Have several old Unos that work superbly, but i tried an R4 and no joy as the speed of my turntable was nowhere near as accurate as with an old Uno.

C'était trop bien, on veut la 2ème partie ! Et les presse-étoupes... DAMN ! BEUBAÏE

du coup faut que tu fasses plus de plans de la robe terminée sur toi je vois que ça <3 Archi fan, j'ai hâte de voir la prochaine partie ! Bravo pour le taff de maboul tous les deux, que ce soit sur le jour J ou pour le montage toujours au top ohlàlà !!

...add piezo & hc-12 (rf) embedded with newer board...

Trop cool la vidéo. Le montage et les plans sont vraiment cool. Et les blagues à Meulin ajoutent le petit côté spicy! Je veux une belle robe maintenant 💃🕺

AMAZING! What I love the most - is that it’s so interesting to watch, even if you are absolutely out of the subject… Émeline is so creative! And Ilann - so unpredictable. Love you guuuuuuys

Super intéressant ! Et Émeline la Queen bien sûr

once your code in installed what are the commands to play a video?

It seems to me that a beginner's development board should have enough current to drive hardware if the focus is not heavy into software like the Raspberry Pi. I personally want to play with components as well as software, but it seems that each board makes you pick between them. Pi is more powerful and is software heavy, but not nearly as easy to learn. R3 is a somewhat limited playground that doesn't include enough power to support PC style interface peripherals. The reason you don't see commercial developers drop what they are doing to use Arduino or RPi has to be a functionality limit that you hit while trying to use them. Bottom line: they are best viewed as a learners' hobbyist toys.

I find Arduino released this thing without making sure the reference material thoroughly covers the programming differences between this Renesas RA platform and the platform the UNO R3 uses. Does a library environment for this new platform exist? For example, try figuring out the interrupts and the available interrupt types. See if the reference document code for interrupts actually compiles or functions as advertised. See if you can get pin change interrupts working. Please show us how if you manage this. I agree this R4 will be frustrating until the public Arduino community catches up with functioning libraries and documentation having functioning code examples.

What I missed in the video is compilation time. In my classroom, compilation time is key. For a Leo, MEGA or UNO it is near instant, compilation for a Microbit is also very fast, Teensy ditto, but for M0/M4 boards is was much slower, and for ESP32 it is unbearable slow (1 minute compilation time!) I do not agree about the confusion with Serial and Serial 1, we use Leonardos for ages, because they have dual UART, which is a must have for GPS, GSM, MIDI and stuff like that. I also hope they kept SPI exclusive to the ISCP header, and no wiring through pins 10-13 as well. Another reason I prefer the Leo over the original UNO: you have extra pins and easier SPI hookup. I also quite often use the 6 extra analog inputs on the LEO, especially for multi-analog-stick gaming projects many students make. I actually dilike USB-C, as the port dies easily in classrooms, and USB-B can be soldered by hand easily, USB-micro is doable as well (1mm spacing), yet USB-C connectors need a reflow machine for repair.

While it's still on market, I'll buy myself another Original Uno r3

C'est déroutant les titres en France, le nom de la chaîne en Français mais l'audio en anglais.

Ce proG é trop cool \(*.*)/

Bon boulot 👏

I really like the new dual serial! That was one of my reasons to use Arduino Mega. When I set up the companion controller as HID, I had to use soft-serial, or Arduino Mega to connect a serial terminal.

In french please! En français s'il vous plait !

Haven't started playing with mine yet. Anyone tried this one with Arduino IOT cloud ? Wondering if there is any more success with this board and the cloud agent, which seems to be seriously flawed. I'm not sure if Arduino just isn't into the cloud implementation long term, or if the development is just a little out of their level of ability. This really could be IOT for the masses if they can get on top of the cloud agent issues.

Somehow, this video made 20 times more views than my previous videos, and it made me double my number of subscribers! So thank you again to everyone who watched, commented and subscribed! This video was released only a few days after the release of the boards, so let me give some updates: - First, the R4 WiFi is now compatible with Arduino IoT Cloud: blog.arduino.cc/2023/07/12/introducing-uno-r4-wifi-support-in-the-arduino-cloud/ - I was able to run a debug session on the R4 WiFi using Platform IO without any external hardware For those who asked for an in-depth review or more code examples, here some nice reviews made by other channels that I've found : - @Dronebotworkshop: th-cam.com/video/kJE9CBb3fT8/w-d-xo.html - @adafruit : th-cam.com/video/uw0EU8urz5M/w-d-xo.html - @esp32 (in Spanish 🇲🇽) : th-cam.com/video/HQ4J0-3RN7c/w-d-xo.html

it's all nice but let's not make it difficult now please! for example I can't work very well with that ESP32 OR!!! a video REALLY needs to show everything step by step and really not skip anything, maybe then it will work with something like ESP32. I am very happy with the simple old Arduinos! ( And honestly, clones too ) Regards Rob

almost all projects in the arduino world require more than enough computing power with the R3. I don't understand the usefulness of this upgrade for the Arduino world, after all if I want to use ESP, I use an ESP... and it costs even less.

Great video arduino's❤awesome🇧🇷😉👍 @arduinomaquinas thank you man and subscribed 👏👏👏👏👏👏👏

THANK YOU FOR THIS USEFUL INF. ONLY ONE SUGESTION. SPEAK MORE CLEAR AND SLOW DOWN NO BODDY IS CHASING YOU.THANKS.

Entry price excessive and a poor hardware solution for a final product. Better to use a board like the dev kit for CH32V208 which has massive functionality at a very low price, all with one microcontroller and a crystal. The popularity of Arduino does not justify using it any more. The CH32V003 are great too but easier to lock your self out of if you mess up with programming on the swdio pin or oscillator source. My current choice for small stuff though.

Thank you ❤

Pour une fois que c'est un français il parle anglais pfff franchement comment voulez vous donner envie au jeune francophone qui ne maîtrise pas l'anglais

MASTERCLASS !

Thank you for the information. Like I wrote in another video the worst thing compared to the R3 is the max current for an output, 40mA as you said in the video, and 8mA on the R4. So you will always need transistors or small relais to command an actuator. So more hardware needed. That's a pity.

Vous parler trop vite cela rend votre accent Parisien très agacent... mais quand meme très instructif ...

Great video. Could you maybe give a list of stuff I have to install to make your code work?

Fabulous overview! Thank you kindly

Be nice if the can had a transceiver on board.

Calling it Arduino UNO is such an stupid idea.

It seems Arduino is trying to get involved into 32bits world. But, I think it would be very difficult to beat ESP32 and RASPEBERRY PI Pico. They are really cheap and very well documented.

Regarding the LED matrix in the R4 WiFi, it looks fun but I wonder how many projects will use it (specially when the board is inside a box or you use a shield). I think this kind of functionality should be on a shield not in the main board.

Nice video, thanks for sharing it, keep it up :)
