In this first of (at least) three videos, we will revisit the Arduino IoT Cloud. There have been several changes to Arduino's IoT product since we last looked at it, including a “Triggers” feature and support for almost anything that can connect to the Internet.
We will build a cloud project using an Arduino Uno R4 WiFi board and an ESP32 Dev Kit. We’ll see how to use the cloud console to set up the boards as cloud devices, associate them with a “thing,” and create cloud variables for them. Then, we will build a dashboard to control our boards.
If you want a detailed step-by-step guide to getting started with the cloud, check out the accompanying article for this video at dronebotworkshop.com/iot-clou....
It will have you working up in the cloud in no time!
Here is a breakdown of today's episode:

01:47 - Arduino IoT Cloud
05:36 - Cloud Console Tour
07:50 - Building a Cloud Project
10:22 - Add an Uno R4 WiFi Device
13:39 - Build a Thing
16:20 - Cloud Project Code
20:38 - Dashboard and Demo
23:29 - Modify using Desktop IDE
28:19 - Cloud Project Demo 2 - Variables and Dashboard

37:39 - LED Code with OTA Update
40:15 - Device to Device
43:09 - Using Triggers
41:47 - Add trigger and test
46:26 - Conclusion
I have decided to make this the first video in a series because there are so many new IoT Cloud features, too many for one video or even two. The next one will cover using MicroPython with the IoT Cloud, followed by an episode about using the Cloud with Amazon Alexa Home devices.
I've also been working with Arduino (I will be presenting an IoT Cloud project at Arduino Days 2024), and I asked them for a discount coupon so you could try the cloud. They obliged, and you can use code DRONEBOTSHOP when signing up for a monthly Maker plan. You'll get two months free, so you can try out the Arduino Iot Cloud for yourself.
Hope you enjoy the video!

The coupon code I have for the Arduino IoT Cloud , "DRONEBOTSHOP", will give you two months of Maker Plan for free. Note that this is NOT an affiliate thing, I don't get anything if you use it! I was a guest at the Arduino Cloud Cafe last month and will be doing a presentation during Arduino Days at the end of March, so I have had several meetings with Arduino recently. I told them about this video and asked for a coupon code, and they obliged. It is good until March 18, 2024. There is also a FREE cloud plan that does not require a code, you can do most of the experiments with that.

[@martypeck9950]

Just tried the code and it didn’t work. Any particular plan you need to use?

[@giampi2602]

@@martypeck9950It works with Maker Plan Monthly subscription (not the annual one)

[@JasonWhitlark]

Bill, I'd watched and enjoyed your videos off and on for a few years, but around December I decided to get serious about this microcontroller and electronics hobby thing, and you have helped me over an incredible number of stumbling blocks! It's not an exaggeration to say I'd have given up without your calm and thorough instruction. Thank you so much!

[@Dronebotworkshop]

Glad you find my stuff useful Jason, thank you.

[@jollylama4773]

my man ... your channel should be the official Arduino KZbin channel 🖖♾

[@TediumGenius]

Another excellent treatise!!! I'll be going down this path more, once I identify how I want to control 220 VAC electric baseboard heaters, and possibly, make a "dumb" water heater into a "smart" water heater. Just SO much to do and this research and purchases are just dragging on!!! Always enjoy your videos! Thanks for all your hard work!

[@TheRealStructurer]

Good timing for my next project! Thanks for sharing 👍🏼

[@JM-jk9vz]

I was just researching this today. Sweet!

[@tubeDude48]

Great presentation Bill! 👍

[@marioparini6951]

Thank you for your videos sir, amazing way to teach. Thanks for sharing your knowledge too, all best for you.

[@jballan]

Hey Bill, thanks for all the work you put in on this channel and your website. I've learned quite a bit, you teach at a great pace and I always look forward to your next video!

[@michaelalex5235]

Awesome, as usual. Thank you.

[@mrcurly1147]

Thank you for your awesome video, per usual!

[@Khal3dMustafa]

This is beyond amazing, it's the best tutorial out there. Thank you.

[@mehrvarzy]

Thanks for your great videos❤

[@paulseidel5819]

Really good introduction, thanks Bill

[@kempton61]

Great video. First time I had come across the Arduino IoT Cloud. Thanks!

[@whitneydesignlabs8738]

Yay! New video from Bill! :) I've been loving all the new IOT stuff available now. POE just became my new best friend.

[@winlose3073]

Very informative thanks!

[@electronics.unmessed]

Very good! Thanks again for a very good tutorial. I will definitely think about some cool projects using this.

[@joshuaoduroadu5376]

Thanks Bill for the splendid presentation. Loved hiw you took your time as usual to explain everything in detail. Would be nice if you make a video on the scheduler feature of the Arduino IoT cloud.

[@TheUnofficialMaker]

wow, powerful stuff! thanks.

[@fullmoonsculpturescom-ej4bt]

Thank You! Thank You! Thank You! I've been designing a 3.5' tall x 3' diameter chandelier lit by 90 Arduino NeoPixel Mini-Button BCB's controlled by an ESP32 for over 1 1/2 years. Your tutorials have helped me overcome several hurdles, most recently, how can I change the lights (functionality). from a remote location via WiFi. Another hurdle overcome! Thank You!

[@your_utube]

Really amazing and sensible stuff. Thank you very much!😀😀

[@GuyTou-cj2hf]

Merci pour cette superbe vidéo 👍

[@johnglielmi6428]

Hey Bill, another great video thanks for your due diligence in informing us on IoT. also just as a heads up here. The PDF and Parts List links are not active on the article page, just thought you should know.

[@marcelo329524]

The best arduino site!! Thanks!!!

[@Dronebotworkshop]

That's kind of you to say, thank you!

[@webslinger2011]

Great Video! Any future update on handling sending/receiving images through the cloud?

[@SuperGed777]

Bill, many thanks for all your work on this and so many other videos. I have a present project for changing bands on an antenna and this is ideal after Blynk went totally commercial . Unfortunately the buttons trigger the pins by just passing the mouse over them, and then pins stay high no matter the button state. I have tried PULL-UP, PULL-DOWN resistors but no result. I appreciate how busy you are but if you have any idea why this is happening I would be very grateful.

[@peter.stimpel]

Bill, please check for the wiring chart of that Arduino. voltage is missing at the board, it seems to me. Maybe you would like to add this to your pinned comment or video description. Edit: seems you run it from USB, so no worries. Was a bit confusid

[@TheUnofficialMaker]

no foul

[@elizabethsrani1965]

Thank you 😊

[@martymehan2205]

great job but why not use fritzing for wiring connections on all videos ????

[@larryb6759]

Nice Demo

[@user-yi7pl5yk7w]

thanks sir

[@John_Mavic]

Thank you, Bill, for the great video. I do have two parts that I don't really understand. My cloud variables are regularly updated. However, I wonder when the corresponding functions are called. I had understood that this always happens when a variable is changed. But that doesn't seem to be the case. I have to call these functions within a loop() otherwise, nothing happens. The second question concerns the Serial Monitor. I use the latest online editor to edit my sketches, but the Serial Monitor button in the browser doesn't function. Am I doing something wrong? Thank you for your help. John

[@juikulkarni8812]

Thanks for the great video, I tried all the code mentioned, but the ESP32 never connected to the IOT cloud. I went to the arduino documentation for such problems and tried the solutions there, but they did not work, please help.

[@martypeck9950]

Thanks!

[@Dronebotworkshop]

You're welcome!

[@stefanoza]

Hi Great video When an agent available for android? Should be great for mobility

[@theloveofchocolate2]

Is there anyway to attach a figma designed app interface to your project?

[@creativemind8573]

Sir please make a video on how to control 4 relays with esp32 while using Web Server and also control with IR Remote and save the last state of relays in EEPROM

[@janpekkeriet3506]

Thats not fun, he is expaining the principles, so you can make whatever you want, yourselves.

[@AVI-xo1kb]

Can you make a tutorial on the OV7670 camera module(non FIFO) there aren't many sources that explain about it in detail.

[@raht3ch]

Hello Bill, hope all is well. I was wondering what is the name of the song in the intro

[@shashanksherkar392]

I hope you will explain Blynk2.0, IFTTT and webhooks also.

[@zyghom]

many are going OUT as far as possible from 3rd party clouds (see Home Assistant, that brings almost everything now locally) but here we are and we... go cloud ;-)

[@bertblankenstein3738]

Yep, I'm not going cloud. Nothing but blue skies for me.

[@davesradiorepairs6344]

I've always wanted to develop my own "Control & Monitor" systems built around an Arduino...

[@walterhartman]

I've been subscribed, but had notifications off.

[@solulogic]

May be you can teach us how to use arduino cloud with wifimanager

[@buffler1]

So...Am I dependent on someone else's server somewhere and on my connection to the www? Is there a version where the cloud is MINE and the control of it is MINE, that is everything is ENTIRELY on MY local network?

[@noweare1]

self host , run your own server in your LAN

[@buffler1]

OK. Is the development done on my desktop with something like a super ide or a LOCAL program, or is www connection required? Still not clear as to where the work is done and where the information is stored. Sorry to be dense about this. In other words, is this a paid service to which I am bound for as long as I want the iot system to continue working or to modify it?

[@MahBor]

Can someone PLEASE tell me how i can add an open WiFi network that has no password? I've been struggling with it since August. Nothing works. And please don't ask me to add a password to the Wifi. It's my school's wifi. I'm building them an environment monitor. Thx!

[@marinpaveskovic5130]

First.

[@petermolnar6017]

This is just great, so nothing new here!

[@Johann75]

I suppore, you have the paid features for free in your account...

[@noweare1]

This is pretty cool. But how is this better than a building your own custom webpage using html, css and javascript for more flexibilty and using websockets. I guess with the iot cloud you can build things pretty easily without havng to know the web technologies. Can you steam video to the cloud ?

[@bertblankenstein3738]

For me the whole purpose of microcontrollers is to not be dependent on the cloud/internet and tinker with this stuff ourselves and keep control ourselves. This video is really good a always, but i won't be using this video.

[@noweare1]

For micro's that don't have wifi you are correct but with them now having wifi connectivity, remote control and remote monitoring is possible.

[@bertblankenstein3738]

@noweare1 yep, I connect them to my own network though, and not to someone else network (the cloud).

[@petergrondman8064]

would be nicer without the cloud. bit f a loss of time xplaining to connect with a cloud. give them your personal data and you are connected. i'm not watching 49.22 minutes of propaganda.
