- Welcome to the world of the new Arduino Uno R4 WiFi! This video will introduce you to the latest addition to the Arduino family. Just like its predecessor, the Arduino Uno R4 WiFi is packed with features that will make your digital and analog electronics projects even more exciting.
This board comes with a Renesas ARM processor and an internal real-time clock, Unlike like the Arduino Uno we used to build a clock in our previous video. But, what sets this one apart is its built-in WiFi capability! Yes, you heard it right. Now you can connect your projects to the internet and take them to the next level.
So, if you're looking to upgrade your Arduino Uno or just starting with microcontrollers, this video is the perfect place to start. We'll unbox the Arduino Uno R4 WiFi, run through its features, and even do a quick project to show you how easy it is to use.

HEY YOU ABOUT TO POST SOMETHING STUPID:
Yes, I know my hands are large/fat. It's because of a heart condition I suffer from called Congestive Heart Failure. Here's a link to some information about CHF: cle.clinic/2TdS2Ux
One of the symptoms is that it causes fluid retention, mostly in the hands, feet/ankles, and face..

Happy New Year, Paul! Awesome video. Looking forward to projects to come.
Awesome stuff! Thanks for the write up and first look at this R4 board. Happy New Year as well.
Wow awesome, I’m really excited to retry this board for auto mods. This is a complete game changer. Ty Paul for sharing this one. Happy new years to you and the fam buddy.
Happy new year. Thanks for the overview of what looks like an awesome board.
Excellent review & intro! Happy New Year!🎉
Happy New Year Paul! I always enjoy!
Happy New Year's Paul
this is the first uno board that made me want one i think most of the time i just a use a nano but this is awesome
I mean you could just use an esp32 s3, what dou you need the rest for ?
yeah, plenty of variations of ESP32 boards for makers to chose from - this smacks of just surrendering to ESP32 instead of being competitively different
Happy new year Paul !
Happy New year, hope you finally got all the money for the channel sorted out and actually started to get paid for your content. Thanks for the hard work.
Happy new year, nothing as yet.
Happy New Year Paul, Blake and Doggly.
Neat little computer. I'll stick to hardware, you can build the software 😎
☮️ brother.
Nice there’s analog out and an opamp though there’s not a ton of audio that can be done with one opamp. Wifi is great, that’s helpful being built in. Don’t really need the display, wish that space could be repurposed as a prototype area.
Design your own.
Happy New Year 🎉🎉 Paul. I just wanted to point out that the ARM chip is a Renesas chip.
"You can see the matric commands work by....just using the matrix."
EEGADS! Where have I heard that before ?
No, you are awesome, well done getting the 100,000 subs UT trophy.
it sadly doesnt have i2s, which would have been waaay greater for audio. the esp32 can, but they didnt give it pins for the i2s on that either so, its okay but not the go to.
then id go with the wroom esp32 or stm32 or teensy i guess. but i love this board, great tinkerer
I still have 3 of the R3 versions and a stepper motor daughter board to stack on one of them. They were limited because of memory and speed for more advanced cnc projects but price wise a super bargain.
I have many more of the esp32 style boards which are even cheaper, faster and have a form factor that works great on bread boards.
This R4 will probably be put out in the mini format down the road.
I wish they would have added a small display instead of the LED array.
We think alike as I too was thinking it's now got the power of a tinsy for audio stuff.
I think we could program digital versions of effects pedals into these and build them into guitar effects pedals.
These could also be used with stepper drive boards to run cnc machines and 3d printers.
It sounds like it's got far more processor than pins to take advantage of all that power but they were trying to maintain form factor for backwards replacement capability. Everything has it's compromises.
There are pads for dinner of the extra IO, but not nearly all of them. You add a pt2399 and a stomp switch and you could make all kinds of effects
I like the idea of a beefy ARM MCU on an Arduino, but there is a lot stuff on it that looks useless to me. I would not have done that LED matrix but a second row of I/O instead, like in the Arduino Due and Mega.
I have the R4 Minima, not really an issue but it takes about 3-4 times as long to ship out sketches compared to the R3, any ideas why?
Probably the IDE, not the boards, the 2.x IDE I used is slower.
I think it is weird that everything is getting an ESP32 bolted to it just for wifi. What is the point of having a low power arduino with a wifi module that has more power in the co-processor as your main mcu. It loses what made the UNO an UNO. A wifi uno should be an ATmega with a wifi chip.
That is utterly stupid.
If you knew about this stuff, you'd know that a wifi UNO can't just be an ATmega with a wifi chip. ATmegas are not and probably will not be made with built in radios, and even if you had a chip to do wifi, you'd still need something powerful like an ESP32 to run the TCP stack.
Also, I don't think you quite get that the ESP32 and the other processor have fundamental differences between them, and it's not as simple as you seem to think.
Finally, you have a lot of arguments that just don't make sense. For instance, what "makes the UNO an UNO?" How is it "weird?" Is it really that the ESP32 is "just for wifi?"
I suppose you could get a specialized WiFi chip… but then it wouldn’t be programmable and it would probably be more expensive. I imagine that a tcp/ip stack would be pretty complicated to program.
I think it would be weird to have some WiFi chip that is not as popular.
Then take an R3 and build your own wifi adapter and network stack since you believe it’s so simple and correct.
It’s a dev board, it’s not meant to be the final version of something, you should be rolling what you need on your own PCB and optimize there. The display on it is far less useful yet you don’t complain about that?
audio is terably low after you use the new mike
If they do this to the Mega I'm there! Have a great 2024!
In your video at the 12 minute mark your volume went really down. It was hard to hear you. I had to turn my volume up all the way to hear you. Just letting you know. Before the 12 minute mark you were fined after 19 minute you were too.
is it too hard to add an on / off button!
Do you know which opamp it uses ?
Built into the IC
@@learnelectronics 👍
I wonder how the 2 cpus talks to each other?
when you switched screens & mentioned your new mic your volume dropped entirely to super low for me
Yeah...
I can use this with my v4 cool❤wonder what opamp lm317
It's a bespoke opamp in the silicone of the Reneses chip. You just get +, -, and Out.
🙏🏼🫡💯🇺🇸🥳🥳 glade to be watching sir. thanks for great content sir.
Happy New Year's to u too sir
