День тому

Learn how to control ESP32 GPIO pins in real-time with AWS API Gateway WebSockets. I will show you step-by-step how to create and build:
- PlatformIO project with ESP32 WebSocket Client (C/C++)
- Serverless Framework project utilizing AWS API Gateway WebSockets, AWS Lambda, and AWS DynamoDB to handle the communication between clients (TypeScript)
- Web Application to control ESP32 from the browser (ReactJS)

@Adityasingh-sq7gd Рік тому

Hi Tomasz, I'm fairly new to this IOT stuff, i've one query, is all these web server using AWS, websocket free or we need to purchase some stuff? You didn't mention anything so it seems this all is free and we just need to purchase esp 32, led , resistor & breadboard. In addition to above, if I wish to create cool IOT interfaces controlling stuff online, I need to learn JavaScript, aws & Esp 32 languages with their several libraries etc, is that right, or something else is required?

@jamesgardner1647 2 місяці тому

You have to establish an AWS account. It has a small number of free connections per month but as volume goes up so does cost.

@AjirogheneSunny 3 місяці тому

As of today 16th January 2024, this code is no longer working. I have spent all day trying to make it work but no response. I went ahead to copy your code base, but still won't work. I think something has broken with the aws serverless

Panie Tomaszu, panski project "Control ESP32 from Anywhere in the world" zwrocil moja uwage w zwiazku z tym ze tej zimy padly moje lithium battery zasilane przez solar panels i calkowicie stracilem mozliwosc wgladu na moja polane kilkaset kilometrow od domu. Postanowilem wiec kupic generator ktory moze byc odpalany przez remote control a to daje mozliwosc zainstalowania w nim ESP32 bo start jest automatyczny i choke jest automatyczny ....calosc zasilana z bateri 12v. Nie jestem z zawodu programista, kiedys naprawialem telewizory a arduino traktuje jako hobby . Moze to bylby jakis pomysl na przyszly projekt...dziekuje

Hi sir, I don't really have experience in Arduino, but can I apply what you explained in this video by using esp8266?

@tomasztarnowski4434 Рік тому

Hi HUSSIN, yeah I think connecting to WiFi and using WebSocket client should be almost identical on ESP8266. You can also check my old videos about ESP8266 they might come useful to you.

@aliaskri982 Рік тому

I give up! This is such a disastrous tutorial for a beginnner. It is ridiculously hard to follow with various components that you expect the viewer to know without ever specifying them. After sinking about 5 hours in this video, trying to understand what you say and then solving all the errors you haven't mentioned including how you have to setup an AWS account, configure that information with your personal computer and so on. At @42:16 , you just paste in code without every explaining where you got it from or how I can get it. Looking over your github repo, that code doesn't match as it contains addtional functions and leads to further several errors. I still have multitudes of questions and errors. For example, when I deploy program, I keep getting erros like secret-key is not defined and etc. I would try to solve it but I don't even know where to start. Only by watching your other vidoes can I even begin to complete the puzzle. As a self-learner with no knowledge of these concepts, you complete ruined the fun of the video. I have self-taught programming through online tutorials and I have never been left this confused and exhausted. Instead of learning something new, I want to cry from frustration sinking so much time into a video while nothing to show for it. What's most disappointing is that seeing your earlier video regarding hooking your esp32 to wifi and about platformio, I got so excited, but wasted my limited time on this 2 hour confusion fest.

@noweare1 7 місяців тому

This was a lot to know. Besides esp32, C and json, you have to know react, javascript and AWS. Thats a lot. One thing at a time then integrate them one by one.

@mtgstudios1556 Місяць тому

I'm not sure that this video was geared towards beginners because of @noweare1's point at least from what I can tell by looking for a solution like this, trying to control the device from anywhere in the world is quite an advanced concept as I can't find a lot of people that have done it from absolutely anywhere. Mostly just on local networks. So if you are still into the IoT stuff I recommend starting a bit simpler than this. like trying to make it work with Low Bluetooth Energy.
