Retired engineer, old enough to be your grandpa. Really enjoyed your tutorial. Discussing really simple steps is critical to start the learning process. :)
I just know ESP32 for camera by combine it with arduino? Actually what's the exact function of ESP32?
@@edibandulan5266 It's basically made for IOT applications - it's an SOC that integrates WiFi/Bluetooth so you can have multiple microcontrollers/processors, communicating with one another over your home network (or on their own private network), and controlling things via GPIO accordingly. They can also do interesting things by themselves - act as a super low power DNS server, and other things I don't understand lol.
@@edibandulan5266 Hi, ESP32 is microcontroller. There are many microcontrollers like TI MSP430 series, NXP KM series, etc. Microcontrollers unlike simple processors come with alot of peripherals integrated into the single chip, like UART module and SPI for communication, ADCs to convert analog signal to digital values, etc. ESP32 comes with, one can say, peripherals needed for WiFi and Bluetooth communication, other than regular peripherals like UART, SPI, I2C, etc. And the processor is very powerful, plenty of memory, and extremely cheap as compared to other chips with similar features. So if you want to give your system, maybe camera, or maybe sensor system, wireless communication capability, ESP32 is a good choice
Thank you so much Tomasz for this brilliant introduction to esp! Your video is very well structured and all your instructions are clear and make perfect sense. Very encouraging and I am really excited to get stuck into this now.
I totally agree with Jack Flash. Your method of explaining and the speed that you show us how to do the individual tasks is perfect. I've subscribed and I'm going to walk through all of your videos. Thank you for putting this together.
I'm really glad it helped you :) Thank you for the kind words.
I have been programming mostly on UNIX/Linux for over 45 years. Just bought an ESP32 and ESP8266 and a starter kit. You got me up in 1 day. Already have my RiverExplorer logo showing on the OLED and connected to WiFi !! - Thanks! I have Halloween plans with an ESP and my 3D printer!
Thank you. Proper ESP32 for dummies start guide. Now to order the board. I'll be back!
Best beginning ESP32 tutorial on TH-cam. Worked immediately on a Windows 10 laptop. Much appreciated! Now on to bigger and better projects :-)
Great to hear that it worked immediately for you without any issues, S Bromley :)
Your tutorial is the most informative for new comers I found so far. Thank you.
Excellent video. Just received my ESP32 board a few minutes ago and I got it up and running with this tutorial. Thank You!!
Great to hear it worked, Jorge!
Bro, you're simply amazing. Probably the best getting started video for ESP32 on TH-cam.
Thank you, Ajaz Hussain!
Thank you. This is a very good introductory video. I am a newcomer to ESP32 and I found it very useful.
Thanks Tomasz, this video is just what I needed to get started. Now I can build and upload and test my code. Many thanks.
I've watched several videos on how to get PlatformIO going in VSCode and this is the best of them all.
I followed along and BOOM working right out of the gate.
Nothing like hands on to get the brain cells lined up.
Thank you
Great to hear that, thank you Jack!
I appreciate the setup video Tomasz. Keep up the great work, it was insightful.
I'm glad you enjoyed it :)
TY! Wish I had seen this before having my connectivity issues. Thankfully I had stumbled into installing the USB-UART driver…
Thanks a lot! This was the only tutorial I could find, which actually went over the multiple types of bridges. I almost gave up before.
Great to hear that my video is comprehensive enough to help as many people as possible!
Thank you for making this very nice, easy and informative video it just helped me alot !!!
Thanks for the great tutorial. I've been and embedded systems developer/IC Designer/Test Engineer, and I have to tell you, VSCode is very difficult to learn. Not only that, PlatformIO helps, but it's tutorials like yours to get one started that are REALLY appreciated.
A suggestion for a project: I2C Audio using a Diligent Pmod I2S. 73's
Thank you so much! Using this with VS code is very comfortable!
I like how you are pointing the hardware parts with toothpick😂.
The video was very informative and helpful 😊
Thank you very much. Great simplified video.
Thank you so much. I was finally able to get my esp32 to work after this. You're the best
Great to hear!
Thank you so much for sharing your knowledge Tomasz! cheers from Argentina!
Gracias, Matias!
Great video, Im just getting started with ESP32 and this was a smashing help.
Thanks, David! I'm glad I helped you!
Thank you, been struggling getting my ESP32 to work. Using the VS editor has made this prodject so much easier. Thank you Tomasz
Hi David, I'm happy my video helped you!
thanks a lot Tomasz, it was extremely useful for me❤❤❤
Thanks for the clear instruction. You are the man. 👍
Glad to help
Life saver! Thanks Tomasz, and keep it up!
Thank you, Nick!
👍 - dzięki za tutorial ! Świetny jest ten ESP32
spoko, nie ma za co :)
This moment kiedy słuhasz jak gość szpraha po angielsku a wiesz że jest polakiem.
Excellent video - thank you very much!
tysm for this tutorial man, fastest ive ever setup a microcontroller with vs code yet
Glad it worked for you, Nikhil!
Thank you for the great video!
Amazing! very helpful
Can you do some bench tests of code performance between Arduino IDE vs VSCode-platformIO? Esp has its own called ESD-IDF and it makes less efficient compilation when bench tested
I don't know if it helps after all these years, but I believe you recommend short cables because your monitor speed/baudrate is way too high...change it to 9600 and you can get a few meters of cable...thank you for the tutorial, helps a lot!!!
I loved your video and your diction, my first language is not English and it is difficult for me to understand it. but I understood you perfectly and you explained very well. keep it up please
Thank you, Jose Alejandro! 😃
SUBSCRIBED!! Thank you very much for the extremely helpful video.
Thanks for the sub, Zahid!
Thanx bro, you helped with the driver.
I thought I needed CP210X, but I needed the CH340 that I didn't even know about.
No problem 👍
I'm glad I could help :)
Great video on that topic 👍
This was a great kick start!
Thank you!
very informative. thank you.
Very nice conetn Tomasz ! This video is a real pleasure for onboarding when starting from scratch
man... u r a legend
Cool video. In my case I use a WROOM32 board and I can't upload a code. So I change board id to esp32dev and now it works. Thanks !
Thank you! I'm glad you've managed to get it working.
Thanks for sharing ❤
Great job!
Crystal clear. Thank you
You're welcome, Pro Edi!
great intro, thank you.
Excellent guide!! Is there any way to write pure C/C++ code without that setup/loop functions? I mean, a tradicional main method, function prototype declaring, callbacks, etc.
Also, can assembly code be used here?
Excellent tutorial. Thanks 👍
You're welcome, M Navarro!
Thank you!!
Very useful. Thank you
Super helpful, thanks a lot!
You're welcome, YourComputerExpert :)
Great tutorial, thank you!
You're very welcome, Lance!
Thank you, this was very helpful. For some reasons, my ESP32-S3 devkit can update programs without pushing any of the buttons. I will have the carefully read the manual.
Great teacher keep on doing
Everything thing is very clear good job
Thank you! 😃
very helpful, thanks :))
Amazing video . I'm actually very new to the iot area , should i learn electronics first ?
absolument parfait, c'est la meilleure vidéo si vous cherchez comment programmer une ESP avec VS CODE 👍👌
Merci beaucoup, Last Hero!
Nice video clip, keep it up, thank you for sharing it :)
Thank you 🙂
Really great video. Thank you:-)
Thanks Andrew. I'm happy I could help.
I was able to follow this flawlessly. You style is methodical and very easy to follow. THANKS.
I have one question. How does VS code know which COM port to use to upload the code?
Thanks for the kind words, David. I'm glad I could help.
In terms of the port detection PlatformIO loops through all the available ports and tries to match the device by hardware id/model - you can find more in this thread community.platformio.org/t/auto-detect-port-explained/16062/2.
Also if you'd like to specify the port of upload you can do it by adding "upload_port = /dev/ttyUSB*" or "upload_port = COM[13]" to platformio.ini config file - have a look at this page in the PlatformIO docs: docs.platformio.org/en/latest/projectconf/section_env_upload.html#id1
@@tomasztarnowski4434 thank you so very much for the detailed response. It is quite helpful.
Great Video please more from ESP32
Thank you! Working on it :)
Dear Mr. Thomaz great tutorial but for me didn’t work, there is a connection error or the computer cannot connect im not a software eng so there is anyway to test the connection between the ESP 32 and the computer it seem the drivers that installed
Using an ebay ESP32 ESP-WROOM-32 ESP-32S Development Board 2.4GHz WiFi & Bluetooth I found LED_BUILTIN didn't work, undefined; found the blue led on the board (other was a red Power LED) is GPIO_NUM_2 , changed that plus used 115200 as the baud rate and it worked. Linux Mint using the VS Code flatpak. Only changed the baud rate because I recognize 115200 not the 921600. Also used the ESP32 DEV Module. Appreciate the video.
we're using the same devices, thanks for the heads up
Great video! 👍
Glad you liked it, thank you!
Ottimo grazie. Saluti dall'Italia
Grazie! :)
Nice video. Thanks for sharing.
Thank you for the visit :)
Which programming language do we have to learn in order to program esp 32
Can you please make a project for esp32 for audio applications like, it will receive audio stream in Bluetooth APTX HD Codec format or LDAC format and outputs the signal as i2s format?
hey quick remark
1 baud means 1 symbol transmitted per second. A symbol can be more than one bit. This is why we don't have to create confusion between bps, bit per second, and baud!
thank you, ziri for clarification. You're right baud is more of an abstract term and what's important is the context :)
Super material, w prosty i syntetyczy sposób opowiadasz jak i co zrobić. jeszcze kilka fajnych projektów (pomiar temperatury, wilgotności z rejstracja na jakiejś platformie), nalepiej z czujnikami po I2C.
Dzięki :)
Very nice video thanks a lot! Could you make an example using a temp sensor and uploading it to the FireBase realtime db please? :)
Thanks!
Good suggestion. I'll consider making a video where I use Firebase instead of AWS :)
So nice thanks sir
Thank you!
No worries, I'm happy my video was helpful.
Thanks!
Hi, Thank you for the great tutorial. I am looking to build a multiroom audio player. can you suggest or create a video?. Thanks
Sounds like a great idea! I'm planning to make a few videos about ESP32 and audio, it may take a while, though. Stay tuned :)
Many thanks, ESP32 now working. I tried some other approaches but they seemed to over complicate the set up, or not support the NodeMCU-ESP32.
Good to hear Chris that my video helped you :)
Hi. Tomasz. I repeated your video tutorial on my laptop with Linux Ubuntu operating system. But before starting the download of HelloWorld code to the esp32 microcontroller, I did't install any driver for uart-bridge CP2102 (I haven't used any boards with any CP21xx chip before on my laptop, for sure. I installed the system just a couple of months ago.). But despite this, everything was loaded and the board passed the LED blinking and sending text to the terminal.
I think at the moment newer Linux Ubuntu versions already support the CP2102 chip out of the box.
Hey, thanks for confirming this with ubuntu. Looks like the most popular Linux distributions support CP21xx out of the box :)
Sir do the esp32’s have any operating system when brand new?
Super materiał, pół dnia spędziłem próbując skonfigurować esp32 w ESP-IDF explorer a z pomocą PlatformIO można to zrobić w 15 minut.
Dzięki!
yes, cheaper than nano, & much faster AVR & memory good build quality, i have one for future projects, haven;t even unboxed it, currently doing on nano's and still figuring pro mini.
On Linux the cp210x and ch341 drivers are included by default
thanks, man. Appreciate it
will share among others as well, don't want to use Arduino ide anymore
I'm glad it helped!
Yeah VS Code with PlatformIO is way better experience once configured properly :)
Thank You Tomasz
No worries! I'm glad I could help.
thank you
This is a great video!!! Thanks for teaching me on the basics of an ESP32.
One question I had is. How do you terminate the process?
When I kill the terminal, the diode is still blinking and it won't stop
Hi Clay,
the code runs on a microcontroller so it will run as long as you provide a power to it so the simplest way to "terminate" it is to disconnect it from the power source although if your goal is to be able to run and kill processes on ESP32 you can either program it so external control is possible (you can check my other videos on how to control it over WiFi/internet) or you can put it to sleep after X number of seconds (I don't have a video on it yet but I'll make one soon)

Thank you for explaining it
Again, very helpful video
Thanks bro................
Hi . Can this work under ubuntu
Very usefull many thx
I'm glad I could help and thanks for the visit, Simone :)
this is a wonderful esp32 platformio vsc video.. platformio is new to me 🤔 is there a simple way to test the esp32 serial2 with rs485 module for modbus rtu master test? thank you.
hey, q zorn, thank you.
I haven't tried to use Modbus with ESP32 yet. I'll look into it in the future.
Thanks for sharing
You're welcome, Kelvin!
thanks!
Thank you so much for this video! I would love to see a video of using this board to display my TH-cam channel subscribers and video views.
Hi Pren, yeah I've got a video like this on my todo list for quite a while ;)
the driver is maintained by the linux if you read the explenation about the download links
Super video!
Thank you very much!
Thank you so much 💓 Tomasz for the great video. I followed through the all steps of video every thing went through. But when I uploaded got error could open COM11, then I device manager in Ports I saw one yellow mark at silicon Lab CP210X USB to UART Bridge(COM11)
It's working. Thank you 😊 💓 ☺ so much
I'm glad that you've managed to fix it :) Great to hear that it's working!

Our HMI displays can work with STM32, ESP32 and Arduino by UART communication.
Could you please make some Sponsored videos for our HMI LCD?
Hey Rainny, for any business/sponsored videos related requests please contact me on my email address that you can find in the about section of my channel:

My Platform IO is taking a long time to create a project, been waiting for a while now
"The microcontroller is just this chip..."
No, that's actually JUST the metal shield covering the MCU. The ESP32-chip is less than a quarter of that metal shield hidden beneath it, and looks very similar to the rectangular Serial-to-USB-converter chip (without leads) close to the USB-port.
Thank you for the clarification Colab User. Sorry I didn't want to go too much into details :)
