Hi everyone - It's come to my attention that there has been someone masquerading as myself, responding to some comments here with a link to a Telegram chat to win a prize from me. THIS IS A SCAM, I am not holding a contest, nor do I have a Telegram account. PLEASE DO NOT RESPOND TO THESE MESSAGES!! It's happening on a lot of my videos, I'm taking steps to remove them manually, but as I have 162 videos, it will take some time. If you do run across a suspicious comment, I would appreciate you letting me know at [e-mail]. Thanks! Bill (The real one!)

This video is a fundraiser for the Hawai‘i Community Foundation's "Maui Strong: Fire Relief Fund" to help provide support for the people in Maui who lost so much. I lived in Hawaii for almost a decade and although I lived in Honolulu, Maui was always my favorite island, and Lahaina was my favorite place. To see it demolished so quickly, and all that loss of life, is just devastating. If you are able to, please consider making a donation. Mahalo!

After trying to get a project working with the memory limitations of a nano, I bought one of these after watching this video. I’ve been missing out with all the extra features described here! Once again, excellent video!

[@alexnewton3376]

Best tutorial ever. You covered all the new features and comparsion with all other previous boards. Just placed an order. Greetings from Toronto.

@@jovialcupid9687 Actually, you got a plug in replacement for a Nano for your money. I just ordered one, though I have several other types, (Heltec, TTGO, DO-IT, etc.) but this will plug right into a custom board I built for a Nano Every, and give me cloud connectivity! So that would be one reason :).

Thanks for a great video, Bill. I've spent quite a bit of time on W. Maul. My parent's condo in Honokawai was spared, but still without power. Condolences to those who lost loved ones and property in Lahaina. Hoping the banyan tree recovers. Big decisions now, for residents and city planners for how to proceed.

Great ! I always support using newer hardware which allows implement more advanced projects. I enjoy using ESP32S3 in my projects!

[@rzerobzero]

I've been wanting to get back into Arduino tinkering (I bult a few projects in the early 10's), but I had been put off by the "curve to entry" as I'll call it. Getting all the things setup and talking and whatnot. Well your video has it all! Basic setup, advanced setup (MicroPython), how to do it, undo it, get started again, all the way through communicating with the Arduino cloud - what a brilliant tutorial!

[@hagfishhagfish9274]

😂 Love the bit about the shirt at the start. I sometimes get comments about my shirts at work because I don't work Wednesday or Thursday, so sometimes I wear the same shirt two days in a row as far as other staff see. Gets even worse when I've got 2 of the same shirt and wear what seems to be the same shirt all week.

[@erikderuiter7475]

Thank you for another video like nowhere to be found on YT. Your detail in presentation and video editing is unsurpassed. One tip for new Arduino cloud users: Arduino has an offer this fall where you can buy an Arduino ESP32 for $1 (excluding shipping...) ONLY when you upgrade to a yearly plan which also is has a 30% discount.

[@aerena]

It is plesure to see your new videos. You are the best.

I really like your presentation of the new Nano ESP32 Board. I've got two Nano ESP32 boards and tried to follow along. However, I run into all sorts of problems with those boards. The main problem is that my laptop loses contact with the boards a lot and receive a lot of FDU-errors. Nothing I have experienced with other ESP32 boards.

[@johnburgess2084]

Thanks for the video. Very thorough and complete.

[@claudeschauber8986]

Thanks a lot for the video. I did not manage to put the board in bootloader mode with the reset button so your advice to put B0 to ground was very helpful. However I found out that there is not yet a micro Python program to connect the board to Arduino Iot Cloud ;-(

[@feynthefallen]

Wonderful Idea, but BOY are those genuine arduinos expensive. I think I'll wait a while until the chinese manufacturers catch up. NodeMCU has always been good enough for me so far, it'll last me a few months longer.

[@jovialcupid9687]

This is just esp32 in diffrent package.. If u want small ESP just buy wemos. U can buy five of them for this ridiculous prince Arduino team littelary took ESP32, put in on pcb with their logo and then they raised price. Next company like apple :)

[@feynthefallen]

@@jovialcupid9687 I think you are doing them an injustice. Firstly, their nano form factor is a lot more breadboard-friendly than the NodeMCU or the Wemos D1 mini (not to speak of the ESP-01), secondly while they SELL boards, they also provide the whole ecosystem for Arduino, which opened up microcontrollers to the general public. They literally did for microcontrollers what Bill Gates DOS did for PCs ( just hope they don't stray down the same dark path). Also they do all their development work in Europe, not outsourcing it to far east like many companies do, which to an extent justifies their prices. True, they no longer are the "by makers for makers" company they used to be, and they had their controversies over the years, but they still have a considerable goodwill banked with me, because I remember what it used to be like to develop for microcontrollers before Arduino came along and rolled up the market. About the nano ESP32, funny it took them so long. If the smaller ESP-modules were a bit easier to come by and I wasn't so lazy, I'd have rolled my own long ago. It's not like it's rocket science.

[@feynthefallen]

@@jovialcupid9687 It should also be noted that the ublox modules they are using ARE really expensive. They are more than 7 bucks on a 500ea reel. Maybe not the smartest choice, given the fact that it literally drives prices for the device through the roof. Also makes me question whether or not we will actually be seing cheap clones any time soon...

[@user-cm8ml4xc4f]

Here are some specific examples of applications for the Arduino Nano ESP32: A temperature and humidity monitoring system that uses temperature and humidity sensors to collect data and send the data to an IoT Cloud service. **A lighting control system that uses a motion sensor to turn lights on and off. **A security alarm system that uses motion and sound sensors to detect suspicious activity. **A smart toy that uses motion and sound sensors to interact with the user. **A video game that uses a screen and motion controllers. With a little creativity, the Arduino Nano ESP32 can be used to build a wide variety of interesting and practical projects.

The esp32 became so popular Arduino company made their own board. I really do not see the advantage of paying more for the same technology. The only difference is the castellated pins and the form factor. Arduino even uses the espressif - arduino core.

@@user-nw4xt9iv9b EVERYTHING is made in china so what?

[@tin2001]

That's mainly an Arduino thing. Almost all other Dev boards just show the true GPIO pin number that the chip manufacturer calls it.

[@johnburgess2084]

Very cool! Thanks. I've been curious about how cloud-based sites like this work to communicate with the "thing". Particularly with respect to clicking a UI widget on the app in the Arduino cloud, how does that initiate a communication to the "thing"? I understand that if I have my router configured properly, nothing from the outside world should be able to initiate a connection with any device inside the firewall of the router. Do I need to open a port on the firewall to allow outside connection to my device? Does the device periodically connect to the Arduino server to see if the server has any new commands for my device? Also, though probably somewhat protected, since the sketch lives in the Arduino cloud, so does the secrets.h file, which has (at the least) my network credentials. This could be compromised by attacks to the Arduino cloud, as well as leaks between cloud accounts, possibly compromising my credentials, and going downhill from there. I know I'm pretty naive about security, but this seems like a big hole to be concerned about. Since my wife knows less about security than I do, that makes her feel even more at risk. Any thoughts? Thanks again!

Standard ESP32's take a long time to upload using the Arduino IDE. Does the new Arduino Nano ESP32 upload slowly as well? Thank you for the excellent video.

I was puzzled when they introduced the new "improved" UNOs when there has been similar ESP8266/32 UNOs out for ages, cheaply. Now I'm puzzled about this. It's a simple ESP32, millions about and very cheap. Has Arduino run out of ideas ? The only thing that might save the day for them is a good tutorial for the board, you should be on commission. I feel sorry for Arduino, they created a brilliant concept but lost the bulk of the sales to China.

[@amelliamendel2227]

It's the db1 series dead then?

[@gr82moro]

Does it mean the ESP32 co-processor is way more powerful than the main processor ?

[@TrimeshSZ]

The ESP32 is the main processor - the "Nano" name is a bit confusing because it would tend to make you think it also has an Atmel CPU on it, but doesn't. It's basically a minimum dev board built around one of the uBlox ESP32 modules - not sure why they chose to use the uBlox module because it has an identical feature set to a bunch of other ESP32-S3 modules while being a lot more expensive. Possibly the Arduino people got offered a really good deal on the module?

[@Dronebotworkshop]

I think you have this confused with the Uno R4 WiFi board, which uses the ESP32 as a coprocessor. This board has an ESP32-S3 as its main processor. Please check out the article for more details.

[@Dronebotworkshop]

@@TrimeshSZ Or possibly they want to decrease the possibility of lower-priced clone boards!

[@jovialcupid9687]

No, it don't have ATMEGA proccesor even. It's littelary ESP32 on pcb with arduino logo (and thanks to that prince went up over 500%). How u can't love this greedy company :)

[@TrimeshSZ]

Maybe, but there is no secret sauce in that module, so it would be trivial to design a board with the same form factor and pinout that had 100% software compatibility. If you don't care about the form factor then one of the boards based on the ESP32-S3-WROOM module would be a good fit, and they can go up to 32MB of flash too. @@Dronebotworkshop
