In this video I show you how to get started with the Arduino R4 Wifi. I am designing this class for absolute beginners. My assumption is that you will work hard and pay attention, but I do not assume you are already an expert. In this lesson you will write your first few programs. I will show you a project that I have done with the new R4 Wifi, and the Sunfounder Elite kit. I have decided to make a new Arduino class, based on the R4Wifi and the sunfounder kit, and hope you guys will join me on this journey.

** Your are a great Teacher sir . In my on going engineering journey i have never seen a techer like you. Thank you sir , please keep it up.👍Love from INDIA .
Love it! I think I would have used baud of 115,200 though
The SunFounder Kit costs $96 and will be very useful for Paul's lessons, however I have the Elegoo MEGA 2560 Project Starter Kit used for Paul's R3 lessons. Since many of the components are duplicated in the SunFounder kit, I simply ordered the Arduino Uno R4 WiFI board for $27. I will order, individually, the sensors that interest me associated with Paul's lessons. Typically these sensors cost between $5-$15. For those having trouble getting the SunFounder kit or if you already have many of the components/sensors found in the SunFounder kit, this many be a more cost effective option.
I can agree with that for the people who already have kits, but not for people who have no kits.
I’m a 39 years old kid new to all this! Can’t wait to start the training
The quality and amount of content Paul M. produces is priceless to learning. Thank you, Paul.
Thanks! Really appreciate that.
Dear teacher, please makes some videos on esp32 with micropython
Thank you Paul for all the work that you do and for all of the great lessons that you produce. I look forward to the upcoming Arduino Uno R4 Wi-Fi lessons!
I can't get the kit here in Ecuador, no matter how hard I try. So I am just going to do the lessons without it and use my Arduino UNO and the kits I have, I know that I will not be able to do all the projects in the lessons but I will still watch all of them in great detail. Thank you, Paul.
I am brand new and can't wait to get started! I come from a pure hardware environment, and I basically need a way to make some output decisions based on some inputs. I realized I needed some "smarts" and not just relay logic. I all but scrapped the idea, but someone told me about Arduino, and here I am. A cursory dive in has me completely fascinated!! It was like when I got an erector set as a kid. This particular video helped me a lot! It convinced me that the Uno R4 Wi-Fi with the kit is a good starting point. I really like the way Paul explains things, because when it comes to the software side, I need someone who can "put the cookies on the bottom shelf". Can't wait to get my hardware and start learning. I've just got one issue... I will drink my coffee hot 😁
you should try iced coffee it tastes really good, and I hope you are not putting sugar with it. lol
My R4 Wifi will be delivered today. I have been through most of your lessons on the R3 and look forward to trying new things on the R4.
Paul, LOVE your stuff. My R3 is now part of a new project I have completed, for some HVAC use, not I want a new Uno and you have convinced me to get the R4 wifi. I will be following you again, you are great.
Hi Paul. I just barely arrived at your lessons, so I'm newbie on all this. Just want to THANK you for all the good work. I appreciate the old lessons no matter the quality of the studio/potential issues with the sound, as the content is quite good. Pretty sure the future ones will be even better. Thanks for your time and help
I'm already looking forward to your new lessons with the R4 WIFI! Your lessons helped me a lot, especially how to best use for interruptsI also took all your previous lessons and did fun projects with Arduino MEGA! Thks!
Brilliant - can't wait to get going. You sure have thought your hardware life span and teaching approach right through from start to finish. Building on your past foundations is just going to make future learning so much more enjoyable and fun. You are a great educator Paul. William . 👍
Thank you Paul! I was waiting for this detailed video to mak the step to r4. God bless you.
Oh wow, I have been waiting for these lessons for 2 years now and it is almost here. I am getting excited. I am an intermediate in Arduino but still hungry for more lessons. I will tune into the lessons and help the people in the comments. Thank you, Paul.🙂🙂🙂🙂
Yes! do it! we need you to make some new lessons Yes! I am so exited.
Thank you, Paul, for the great Arduino R3 course. I finished that course today, January 23, 2024, just in time for the Arduino R4 course due to start on January 25, 2024.
OK, and be patient as these lessons will go back and start with the basics. We will get to the new and exciting stuff soon enough, but we dont want to leave the new guys behind, so will start at the basics.
@@paulmcwhorterQuietly standing by. I totally agree with you about starting with the basics. Your target audience is high school students, not 80-year-old guys like me. Having said that, your courses are a joy to "makers" of any age. Keep up the good work. Bob
wow, talk about getting done just in time for the next Arduino lessons.
Even thought i have all the stuff, i get a SunFunder Elite Explorer Kit for this incredable lessons :)
Really LOVE your arduino lessons😉
Bought the R3 starter kit a week before i watched this video. Lol
Thats ok. Will follow the old R3 lessons then buy the R4 and follow those.
I am new here but I enjoy listening to this new educational information coming from this new Arduino UNO R4 with WIFI, as of now I am still on the Arduino UNO R3, Thanks Paul!
Hi Paul, Thank you for your time and expertise, and for creating this channel,your way of teaching for me is perfect.I too look forward to this new course,once again many thanks Paul.
Thanks for the review of the R4. Hope you'll keep the R3 tutorials up as I'm still working my way through them and they're great.
Hi Paul, I am on lesson 60 of the original Arduino course, but I am willing to start the new series to be able to interact with you and the class. Will order the new kit today. Thank you. Bob
Great perspective on the user base of various boards. Thanks Paul
The best teacher in youtube.
Learn a lot from this guy.
I agree👍👍👍
You're a good man Paul! Thank you for all of this!
What a lovely surprise, cannot wait for the great content, thank you for this channel!
You are awesome! I have just followed your link to buy R4 wi-fi and associated kit and look forwards to your amazing lessons going forwards. Iced coffee, no Vodka! 🙄
Wow ! Looking forward to the New Series with the New Arduino 4 wifi . Thank You so much
Looking forward to this new series. I ran across your previous Uno series and enjoyed it though it was 4 years old. It will be fun to follow along in real time. Keep up the great work, I enjoy all your series on MCUs and programming languages
These R4 lessons will go all the way back to how to blink an LED, but we will get to the exciting advanced stuff soon enough in the class. I just never want to leave the new guys behind. Appreciate patience from the more advanced audience.
@@paulmcwhorter I am rusty on my basic electronics as I haven't had to use them in 35 years and learning languages like C++ and Python is always fun. Being retired affords me the time to sit and experiment. Thank you for your efforts and for teaching younger students the basics and getting them involved in engineering.
GREAT VIDEO need/want more live streams! will be glad to start Thursday lesson on Arduino R4 wifi. I have both version of the R4 and have ordered the Elite kit.
I really loved your Arduino R3 videos and I'm really looking forward to the R4 lessons, I Hope you can make a very large series of videos from beginner to more advanced projects. your R3 videos left me wanting more because they were so good.
Indeed, these lessons will start with the basics, so we never leave the young guys or the new guys behind. I want them to be friendly to new enthusiasts. The lessons in this new class, however, will go much further, and much deeper than my original arduino class. I have a better studio, the R4 is a more powerful board, and we have some really exciting components in the new kit. Buckle up, and hope you will come along for the ride.
Wow ..., this is gonna be my first time live ... , hopefully i wont miss this .
Happy New Year 2024 Paul, glad to see a new course about the Arduino R4 Wifi. 😀
Having taken the Arduino R3 course, this will be a great review and to know a little more about this new version. 👍
I'm a beginner and this just came at a perfect time for me. Looking forward to the lessons.
Welcome Aboard!
Extremely good summarized. Thanks Paul
.
Thanks Paul for all that you do! I will be switching over to the R4. 😊
Very good video! ❤ Please continue r3 tutorials with 35 sensors kit. This will be very good to make our own projects and repeat with our knowledge
Just went through your Arduino courses! Loved em, can't wait till you release the new ones!
Think you'll go through some more complex tutorials? Maybe tie some projects into some tutorials?
Yes, this will go into much more depth than my earlier class.
Looking forward to the new board and IOT cloud, and the new training.
Nice one Paul thank you. Been waiting for someone to explain this board
I`ve just used the Pro Micro to control an automatic blind. Very good. I was fed up with all my old arduino`s that would not connect to the laptop. Old boot loader or COM errors.
excellent intro---what is that fantastic background with the winding water and birds flying?
I sit overlooking the headwaters of the mighty River Nile.
I havent checked in with pauls lessons in about 2 years. I ve been working on pulse motors and some woodworking. Im not one for the pi so I will follow these upgraded arduino lessons again. Btw I am now studying pc networking and Comptia so I know the new arduino was busy connecting to wifi via the DHCP protocol.
This new class will go back and start with basics, so the new guys dont get left behind, but I plan to take these lessons much further and deeper than I went in those old classes.
Hi Paul, like loads of other techboy fans I just wanted to ask if you could still keep the older vids on the channel available, I got a few projects on the go and I always need to look back as I forget bits of the code. I am really excited about the new r4 wifi , got mine ready and cant wait to see what it can do with you guys. Paul i know you need solar power out there..any chance of some stuff on solar, maybe nice to recharge a phone or understand a bit about energy..or with wifi about remote controlling house stuff like lights or turn the heating on or a coffeee making machine or security sysytems..your the best , GO PAUL!!!
Will not remove any of the old classes.
happy new year, Paul! thanks for all that you do for us 😃 your videos have helped me a ton with grad school!
Remember me when you are rich and famous.
Would you leave on the channel the current educational Arduino classes.

Hello, Paul, I hope you are doing well. I'm excited for a new series! Let's do this!
It looks like you will present some interesting content, Paul! So much that it looks like Amazon sold out already. Lol
I will have to wait for them to get restocked.
Have a great week!
Hopefully they will restock soon!
I ordered the new R4, looking forward to more lessons. I am less excited about moving away from the Thonny and micro python format we use with the Pico W Thanks Paul.
DrD, we have lots more lessons to go in thonny on the Pi Pico. Those lessons will continue for a long time. This new class will start with the absolute basics, which you might already know, but it will be good review. Then soon enough we will get to some really exciting new stuff. Thanks for being a part of these classes. I enjoy watching your homeworks.
@@paulmcwhorter Fantastic Pico and R4 simultaneoulsy. I have been falling behind on the homework. I will do better, promise.
Thanks Paul! New series looks great
Thanks for all of your hard work Paul, your a top man.
I appreciate your efforts with the R4. Will you be going into interrupts and timers??
great review as usual... The 96 led matrix is refreshing...
(Reminds me of the micro:bit's 25 led matrix. One question though, are the 96 leds charlieplexed meaning that they are sharing some pins.... or they have separate driver....) Anyways, keep up the great work and in my opinion there is nothing wrong with your first series of Uno3 - content is what matters! Cheers.
Hi Paul, I think I can speak for everyone and say that I am very excited about the new class on the R4. Can you try to work in some classes about Alexa or Google home integration? I like to make small projects and it would be nice to have my Alexa start them with a voice command.
Thank you Paul!
Loved the cat video reference!
I love your lessons! Keep up the great work!
I am almost finished the Uno R3 lessons (64 of 68). The code and software for the IR library for the versions you were using for IR is no longer supported. Ironically this happened the same day I watched your R4 intro, so it drove home the point about keeping up with the latest technology including Arduino's. Looking forward to your new R4 Wifi series. Paul where is the best place to see some directory or starting point to find all of your lessons on specific topics? I was thinking about GPS. I found some older GPS tutorials of yours I didn't know existed but wonder if there are some newer ones and possibly newer components. I am also looking for hardware and methodology for measuring angles between lines or planes that are remote from my vantage point. For example how could I measure the height of a building or tree with an UNO and some kind of sensor(s)? If I could measure a couple of distances and angles I could do the trig. to calculate the results OR maybe components exist already do that for me!
As a complete newb (I’m not a stranger to software developing, but never tinkered with Arduino, I’m just about to order my first Arduino and start learning), I’m a bit confused about the WiFi limitation:
1. I thought the WiFi limitation would be the easiest one to get by, expecting that there are WiFi chips/modules whatever they might be called that you could just hook up to your Arduino board on some pins and have WiFi. As for memory and cpu, seems a lot harder to go around the limit - I mean, once your code and libraries are optimized as much as possible, and that’s still not enough, then there’s probably nothing more you could do…
2. Looking to order the R4, I was thinking it would be best if I get the non-WiFi version, and separately get some sort of WiFi module (if something like that exists? Haven’t looked much into it yet)… my logic is: if I want to create a product that needs WiFi, it would need to use some sort of WiFi chip/module on the final product. And I’m thinking that maybe working with a separate/external connected module could be different than working with the built-in one? In terms of code and libraries? Plus, maybe for a final product I would need to learn how to connect a WiFi module anyway? Like wiring and/or the transistors involved (if any) and such? Because, as far as I know, you wouldn’t use the Arduino board on the final product, but need to create a pcb design and have a PCB manufacturer to manufacture the board. Am I wrong in my logic? (I hope I am)
Don’t know anything for sure, just thinking out-loud, asking… Like I said, I’m a complete newb, looking to get into Arduino.
P.S. also saw some video mentioning the 8mA limitation on the gpio pins on the R4, compared to 20mA on the R3 (maybe you will mention it too later in the video, don’t know yet, I paused to write this comment. I have no clue what that means. To me, it sounds like a big limitation, like “you will not be able to use things (sensors, modules etc.) that require more than 8mA”? And would most ”things” require more than 8mA? Or not? I don’t even know if the question is stupid or not, I have absolutely no electrical background :)
Hi Paul, Thank you again for the very informative and superb videos , i have ofcourse 2.3.0 and its there after the upgrade and cannot revert back to 2.2.1. Also will these videos in future be available to learn from and how can i make a contribution towards your lessons if i may.My bible study is going very very well and thanks to you for introducing me to it and it is the one most important and favourite part of my daily routine to kneel down in prayer. Thank you again
Hi again Paul! SO I got my Uno Rev 4 wifi and I am thrilled with it. Except. I have not realized, after playing with the featured RTC (one of its strong selling features) that it has very poor timekeeping accuracy. What a disappointment. Do you have an comments or experience with this, and any easy fixes, or any news of what Arduino corp might do about it? Its a pretty major weakness, given its an actual selling feature. Thanks! Steve
Word to the wise. The link to your amazon kit is going to a 'minima' version. At least for UK audiences ? And NO 10-axis IMU ... A newbie might not be getting what they think ? ... 🇬🇧
See you soon.
The Arduino UNO R4 WiFi merges the RA4M1 microprocessor from Renesas with the ESP32-S3 from Espressif, with its built-in Wi-Fi® and Bluetooth® capabilities, the UNO R4 WiFi offers an on-board 12x8 LED matrix. Sounds interesting. I hope it will work with my Android smartphone for remote project monitoring. 🥳 This R4 will be a great 2024 learning class.
PS I love the math of what makes stuff tick. The animation is the icing on the cake. I just ordered the kit. Arrival time Jan25?
amazing paul, cant wait
I am addicted to iced coffee no sugar now 😂
Mission Accomplished!
Hi Paul your link just takes me to the Ultima sensor kit I cant get a Elite Explorer kit from amazon hear in the UK
I would of been really excited about the R4 but with the esp32 boards from espressif have already stole their thunder.
Thanks
If the new board can be assembled with driver plate for step CNC motors i mean if the footprint have the same size of location .?
Hi Paul, It's great to be back on the channel! I've "heard"... that a lot of Libraries have compatibility issues the new Arduino Uno R4, which is why I've been reluctant to move towards the R4 for now. Is there any truth to this?
I am sure it will take a little time to sort it out. But because of the popularity of the platform, the community will respond by getting things working.
Hi Paul, I think your courses are great. You, quite rightly, assume we know nothing so we don't get lost too soon.
I followed your link to amazon, and the kit shown there has a "minima" not a "wifi" and doesn't have the rechargeable power module. I obviously can't judge the other sensors.
Have you put the right link in?
The link takes you to the correct kit in the US. If you are in another country, and amazon there does not yet have the kit, it might be redirecting you to a similar kit. Unfortunately, I can not control how amazon redirects such links. Definitely hold out for the WiFi kit.
@@paulmcwhorter Thanks Paul, good advice, I will. It will be a few weeks, I expect, before you get to anything R4 specific.
PS I'm in the UK.
I already have the Arduino R4 WiFi, but the kit is sold out on Amazon and isn’t available at Micro Center either. Any other solutions with or without the Arduino itself?
I wonder your area of knowledge... How do you know all these things?? Outstanding sir.. 🙏
I make a point to learn something new every day. Keep learning!
I'd love for you to do an update on this. The fact is that R4 is all but DEAD. I have one, and you can not find libraries for most hardware, such as shields. Shields are mostly still incompatible, and the fact is that no one wants to update their libraries. It has basically become like other discontinued 32bit arduinos... a dead end.
Will the course start next week without the kit being available? Amazon has UNO R4 WiFi in stock and can be had for $28.50. Should I buy one now?
I would wait for the kits. The first lessons will be review and could be dont on an R3. More advanced concepts using the R4 unique features will come later.
Thanks!
Thanks! I really appreciate that a lot.
Your popularity shows! I cannot buy the kit as Amazon is now out of stock! I didn't move fast enough.
Just wait, it will be back in stock. Right now there is a high demand for the Arduino R4s.
I don't know if the kit on sunfounder is the same as the one on Amazon, the sunfounder price is $95.99 USD with free shipping. Should I buy from sunfounder or wait for Amazon? Should I buy an acrylic case or is a case included?
Hi Paul, would you recommend it for beginner? I really want to start with Arduino for my future projects but i don't know what Arduino board should i buy.
These lessons start at the absolute basics, so I do recommend going with the new R4 WiFi
I dont want to waste an entire arduino r4 board for every finished project, with the dip chip i could swap the programmed mcu in a custom board, How should i do tha Same with this 100 pin micro mcu?😢 Please help!
Hi Paul, I see that you have worked with BeagleBone before in your previous lectures. Are you able to do a tutorial on how to use the BeagleBone Servo cape and BeagleBone Black and BeagleBone AI64?
No, there is really no user base for the beaglebone platform. I invested a lot in making that first set of videos on it, and no one ever engaged, so dont plan to work on that platform any more.
Thanks again, Paul
January 16, the kit is out of stock (amazon Link)
Paul, The Arduino UNO R4 WiFi board is available stand-alone on Amazon. Since the Sunfounder kit is sold out, is it possible to get a parts list for the new series so we can buy the UNO R4 WiFi board and components separately? Thank you very much in any case! Michael
More kits should be available soon. The kit I am using does not come without the R4, so might have to wait a bit for it.
I added to my Amazon wish list and will order as soon as it is available again. I can't wait to get started. Thanks Paul for all your lessons and sharing the knowledge.@@paulmcwhorter
thanks papa!
Help! I enter comments on the new lesson, and they disappear. What is going on?
😫 from beginner again? Well, that will give me time to get all the stuff together again 😅
Any chance we can program with more functions and go a little more in depth into object oriented programming this time around?
And more interrupt stuff too 🎉
Yes, I like to go back to the start so we never leave the new guys behind. This series will go much further than the earlier arduino class, and we will be looking at more of the hardware features of the board. So be patient, we will get to the cool stuff soon enough
@@paulmcwhorter Thank you very much, I also think that some I2C section with sensors in a buss would be good as this was not shown in the original and is not that complicated, we used plenty of serial but nothing like 485 buss protocols that I still find in Hydraulic valve packs in my industry.
I went ahead and did some HMI development and design with the NEXTION screens as they seem to be popular but because of limitations of image manipulation moved to the STONE HMI and finally landing on the raspberry zero 2 w and KIVY...
All thanks to you SIR.
love you master
🚀🚀
how should we install this newer arduino ide on linux (ubuntu)
Do they have a kit without the R4? If so, what is it? I want to have a kit, but do not need a second R4 at this time. The kit is also on backorder, most likely due to R4 supply chain.
Do not know what to tell you. I think Paul had the kit made for these lessons, so I don't think there is another kit just the same without the R4.
Its in stock now so I can order it.
"URGENT" Hi Paul, Amazon is out of the Elite Kits what do you suggest? "URGENT"
There is a shortage of R4 Arduinos, that is what is holding up kit deliveries. I would wait until the kit is avaiable. The first lessons are going to be review and could be done on the R3 as we wait on the R4's
can we just get a killer app that will port any all arduino app code to the esp32 so we can just skip all these low power wannabe arduino upgrades ?
I enjoy these series. One itsy bitsy aggravating thing, though. You are repeating yourself. If you want FULL attention, your audience will hear and understand you the first time. If they didn't, another round won't help.
The kit is currently unavailable at Amazon! I know you have tried your best but commerce doesn't play fair! I tried to do your robotics course but the ONLY newer model available on Amazon wasn't compatible with your lessons. I also tried the color display that also didn't work so well. It is not YOUR fault. The newer version of the SAME robot from Amazon should have been backwards compatible and the color display newer libraries should also have been backwards compatible. They just discontinued the older versions entirely with NO hope of support for their previous software / models! POOH POOH to all those companies that just release new items with NO backwards compatibility to their earlier versions, except Arduino, which IS BACKWARDS compatible as you state in this video!
When my review dropped, the sunfounder kit sold out very quickly. The issue in the supply chain is availability of the Arduino R4's. They are not easy to buy in quantity right now. Hopefully the supply chain will free up soon.
"There is never enough memory." - Any programmer
True enough John. I made the same plea in the 1960s, so I had to learn about subroutines, overlays, and common areas in Fortran IV. How much easier it is today :).
Hi all.
Can´t you talk metric? That would be a lot more talking like an engineer.
Actually, an engineer is comfortable working in any unit system. I used to work in the Furlong/Fortnight/Stone system, and could solve any problem using those units.
pretty nice
