NEW Arduino UNO R4 WiFi | FULL Walkthrough!

[@christopherleadholm6677]

Ordered one, actually, my dad ordered one for me for my birthday next week. He said it's already arrived... excited !!!

[@programmingelectronics]

Cool! I need to get my dad to order me some of these :)

I just wanted to thank you for posting all of the great Arduino tutorials. You've been at it a long time. I was just watching one that you posted nine years ago! But still very relevant and extremely helpful to an Arduino newbie. I will probably only make one or two projects, running a Stepper Motor for a Power Feed on a large machine tool, but I still have to learn quite a lot about wiring and coding an Arduino to drive, adjust speed and control Switches, Potentiometer, Rotary Encoder, etc. Your videos have helped me get my test project up and running. I still have more to learn to get everything working the way I want it to, but I just wanted to take the time to say "Thanks very much". Regards.

[@programmingelectronics]

Thanks! Yes...been doing this a while :)

[@felixmartinez357]

Fuggin' FANTASTIC in-depth breakdown! I had been seein' this guy around (how could you not?) but hadn't heard enough about 'im (pretty particular about what I buy anymore)to make a good, solid opinion. This was a perfect fill to the reference in my head about this board! Outstanding.

[@programmingelectronics]

Thanks Felix! I had been afraid I went on too long, but it did have a lot of features I had wanted to cover...

[@anthonycalia1317]

Nice Job. Concise and informative while staying at the correct level of depth.

[@programmingelectronics]

Thanks for watching!

[@gazzacroy]

this is cool. i really love the uno and i like that is 5volts because a lot of stuff i use is 5volt and not 3.3 lol. thank you for the tear down i must get one of these :)

[@programmingelectronics]

Thanks for watching!

[@arthurfricchione8119]

Yes the Arduiano R4 WI-FI with the ESP32 processor. Thanks Mike 👍

[@tb303wpf1]

I love your channel sir. You have such a talent for teaching. Your way of explaining things is both easy and quick to comprehend. And you have a way of helping me retain the information by associating the info with other things. You're an amazing instructor! The fact that you speak perfect clear English is just icing on the cake. Thank you for helping to pave the road for my programming journey. 👍

[@Elektronik-1]

The "auxiliary processor" Esp32-s3 has about 10 times the computing power of the RA4M1 CPU. Can this also be used with the Arduino ide?

[@johnglielmi6428]

Great info on the new boards. Def gonna get one of each and play around with them. I like experimenting with new tech, because you learn a lot about the power and functionality of these microcontrollers. Do you do a series on SBC's as well? the Raspberry Pi and such great and useful tools as well.

[@programmingelectronics]

Thanks! Don't have a series on any single board computers yet, but something I've definitely considered.

[@RuchiSharma-w8k]

Just subscribed! Liked this channel very much! You have a subsciber from India!

[@h2o40fpv]

Great stuff thank you for this video.😊

[@programmingelectronics]

Thanks a ton for watching!!! Really appreciate it.

[@tomphillips2473]

Thanks for a great intro! Is the ESP32 fully functional on its own? IE would I still need a ESP32 board for those type of projects or does this one cover both an Arduino and esp32.

[@tonysicily2687]

Apart from debugging purposes, what’s the point of the led matrix? The rest of the upgrades were very useful?

[@vnzlb]

Hi guys! So, I copied his code (in 11:38) for the LED Matrix and successfully uploaded it into my Arduino R4 Wifi, but it's not doing anything. Anyone knows why? Ty!

[@EricAdamsonMI]

Do you still have that ancient set of Archer soldering aids from Radio Shack? (The tool you're using as a pointer suggests this. Of course, I'm sure those were made in China, and could've been sold under several brands.)

[@Kruemel03]

Is 8mA enough instead of 20mA or is it possible that this could cause problems?

[@AbangKucai]

what i found the good side for this uno r4 is good for beginner because of pin protection , just curious about what they say 5v i/o logic that most sensor use 3v3 i/o logic that means really good for using esp32 put directly, they put esp32 as co processor feel like less capable processor 🤔🤔🤔

[@arthurfricchione8119]

Mike is this course included in the all inclusive PEA course. I belong to the all inclusive course or is this a separate course enrollment. Thanks for any info. Artie👍

[@programmingelectronics]

Hi Artie - thanks for the note! With a PEA membership you get access to all our courses. Is there a specific course you are referring to?

[@RobinHood-zi9ct]

As it can use keyboard and mouse libraries, does it also appear to a connected computer as a native mouse and keyboard? Like 32u4 and SAMD based boards

[@DIYRobotGirl]

With the wifi on the board and the more memory. Could we put the amazon alexa api on that board?😮

[@UltraViolet-tf4vb]

Ganda! Salamat sa Dios💜

[@clentargerototing2792]

can i create a project like connect my sensor wirelessly using my arduino r3 board?

[@Steve.191]

Thanks 👍

Thanks for watching Steve!

[@Zilla922]

How long is the wait time for shipping i can't wait anymore i'm too excited them 😢

[@bteck2005]

What can Arduino R4 deliver, hardwarewise, that ESP32 couldn't? And the price difference!

[@plazmaguy13yago9]

backwards compatibility and 5v logic

[@TAmzid2872]

I'm a beginner and I am wanting to buy an arduino. Should I get this or the Uno rev3?

[@AmmoBops]

If you’re a beginner it doesn’t really matter… tbh it’s just down to how much you want to spend.. and also libraries…(which make coding easier by providing simple functions for complex components) are more available for the R3 and not all of them transfer/work on the R4, so it’s all up to you. The R4 first of all allows you to code up to 16x more in a sketch (SRAM) And the debugger 2.0 sounds really neat and could speed of the process of showing beginners how and what their code is doing step by step.

[@TAmzid2872]

@@AmmoBops oh ok, I guess im going to ge the r4 as it has more features for 10c less.

[@zeeshanakram8751]

Sir! can we use USB barcode/QR code scanner with Arduino uno r4 minima , without need of USB host shield? if yes, can you please make a tutorial on it please ....

[@zeeshanakram8751]

Need your attention please sir!

[@programmingelectronics]

Is there a specific code library you are planning on using? You'd want to check it is compatible with the R4. The R4 can act as a human interface device (like the Arduino Leonardo)

[@zeeshanakram8751]

@@programmingelectronics let me ask my question in different way! can we use Arduino uno R4 as USB host without extra hardware like USB host shield?

[@Brandoncollins-dp8op]

can Arduino Uno Rev3 connect to wifi? if not what do i have to buy to make it connnect to wifi? i want to make it where it's able to send email

[@xmegaxmega9310]

hi. where i can find the registers discription of A4M1 microcontroller? i download the datasheet but i dont find anything about registers and thanks for this useful video

[@argvSys]

(Pretty late)- Trevor makes has a video called "Arduino UNO R4 easter egg" where he uses the registers for a very simple program. You can watch his video to get an idea

I don't get the two processor package thing. That esp32 can do everything.

[@djksfhakhaks]

Welp! You answered that question.

[@stevenlightfoot6479]

I got mine a few weeks ago, very happy, but discovered that the RTC is wildly inaccurate. This is a huge disappointment, given that Arduino uses this as one its strong selling points. Any thoughts or experience with this? Thanks.

[@MStoica]

Complete noob here, looking to get into Arduino. I’m confused… you said the R4 outperforms the R3 by every facet. But also said that the GPIO pins are limited to 8mA, compared to 20mA on the R3… Doesn’t that mean the R4 is limited in that aspect? I assume that whatever you might connect to those pins has some current requirements, and could very well require more than 8mA? So we would not be able to use many of the existing things you might connect to those pins? I have no electrical, no engineering and zero arduino knowledge, so I am confused about this limitation… To me, it sounds like “if, for many years, it was 20mA, I guess most sensors and whatever you can connect to those pins were also made to work with/require more than 8mA, and wouldn’t work with 8mA”?…

[@programmingelectronics]

Great question! The R4 is based on a modern microcontroller that is designed to run on lower power - this has been the trend for many years now. Generally speaking, a microcontroller is designed to control things, but not necessarily source the current to the components you attach to it, that would be more a part of the design outside the microcontroller. It is the case that the R4 would not be advised to use with Arduino Shields that depend on that 20mA current limit. Hope this helps some!

[@Cen_t1369]

bro please I can't find this anywhere... can the r4 be connected from the normal android charging cable?

[@cinemasurge1851]

It has usb c so as long as that cable is a data cable yes you can use it to connect to a computer

[@Electronika-Technika]

be careful with the rev 4 - it has no compatibility for usb host shield library , therefore, you cannot us a usb host shield... I learned this the hard way. The rev 4 wifi does not have a AVR core like the Uno rev 3.

[@VandalIO]

Can it run windows ?

[@programmingelectronics]

It cannot.

So the R4 can run the same sketches as the R3. Do they have a Fast LED library for the R4 yet?
