A great video. You managed to be informative without making the video excessively long. I learned a lot in three and a half minutes. Keep up the good work!

like stark, nice advance man!

My experience has shown that ST supports a wide range of products and support for small microcontrollers in the industry standard (we use at least AEC-Q100). The prices starting at one million pieces are also interesting. Or the advantage of being able to buy pre-programmed chips with your own software. As a company, you can than have a personal contact person who can support you with technical questions in this regard. To be honest, this is probably also possible with Microchip, Freescale, NXP or Texas Instruments. All of them has AEC-Q100 qualified products. Arduino boards and software are just for playing around a little and trying something out quickly. They can do that quite well too. But not to build a long-term, stable system that combines price, quality and stability. It's expensive, very slow, the code is extremely bloated and not stable. All things that can't be used in the industry. (except Tesla, 😅 they use cheap consumer certified electronics)

Cool

Nice! I am also into electronics. Looking to network with like minded individuals like myself.

Easy to figure out why if you dig into the code. Often subpar and over complicated. Great for plug and play hobby dev, not worth the money saved over writing your own for professional organization.

There are Arduino controllers, Arduino based dev boards, Arduino IDE is for software development for various different microcontrollers. The microcontroller used in the video is an ESP32 and is an excellent and very powerful controller with ample RAM and ROM storage. It is designed for industrial use.

Arduino itself is just the software ecosystem. Which is infact used in some industries. But the Arduino boards (Uno, Mega) are very basic and old and they are hardened for industrial scenarios for example EMI filtering, protection circuitry etc. TLDR: uno, mega boards are not used in end products or industrial environments Arduino Software(MCAL) (not the IDE) is used in many commercial projects/products

Arduino signal processing is limited to 16 MHZ where as real time industrial controls can go up to 1 GHZ speed for real time data processing and controlling switches, actuator or reading sensors. From that perspective Arduino is good learning product but not used for real time industrial applications.

Arduino is not used in industry because of code certification problems (software) and bad emc design of the boards (even stm32 nucleos can generate problems). And to mention the esp32 is refered by esprif as a hobby mcu only.

the Arduino framework is just a hardware abstraction layer, with a high enough abstraction so that it can be used on many controllers and by many libraries. High abstraction often comes with the cost of lower customization and larger memory footprint. However, I don't see how an ESP32 + Arduino couldn't be used even in some automotive applications that don't have real-time requirements.

Great work.

Great work, brother, we do not see so many of us doing great work in this field.

it's development kits. just to try the idea. If the idea matches your wishes, you can start the mass production process using economical PCBs and components.

in an industrial setting, you can pick the chip that just fits your needs, leave out all pin you don't need and probably bet a smaller, cheaper, less easy to reverse engineer solution, more rugged and even have control over QA and testing processes. This is like asking why nobody uses LEGO or FischerTechnik in industrial solution - because there are better and cheaper ways to do it IF you can handle the upfront cost and development time.

Because Arduino is a toy.

The biggest reason I've heard of is lack of agency ratings and if you use Arduino code open source, then you don't "own" the code. They can come after you if you bootleg the software agreement.

don't know what you're saying in this video but arduino's can just die any time.

The author does not really understand why Arduino is not used widely in the industry. Not worth watching.

Amen

I would make a good sugestion to all of you, give it a try to Zephyr os, is it true the learning curve is long but believe me , it worth it.

There are better and cheaper alternatives than Arduino. Raspberry Pi Pico is one.

Because Arduino and other Prototyping platforms like PIC, based boards are just for prototyping only as the name implies, Not good for specific job, Example : for simple project like Led dimming or blinking there is a specific timer ic available, there is a no need for Microcontroller here, for advance circuit involving adc's, calculations specific microcontroller ic is only used like STM32 or other, not entire board that doesn't make sense. In General Prototyping platforms are just for prototyping not good for any single production application.

Arduino is still amazing, it's growing and its developing new controllers. The arduino ide is a first choice, it paved the way for thousands of new programmers. Plenty of useful electronics use simple microcontrollers. Overcomplexity works well if you are trying to keep your stuff secret, however Arduino ide is open, and it uses standardized libraries. Users are sharing ideas, sketches and concepts in a open minded community. A DIY mentality is a healthy outlook for the world.

Ardunio isn't. Atmega is....

I always take it that Arduino is a hobbyist pursuit and not much if anything at all beyond that. Too much abstraction.

Nice

As a retired electronic engineer, i never used the Arduino for a few reason, 1. Cost is too high for a very low performance, ie esp32 in bulk is cheaper then an 8 bit Atmel, 2 Size, the boards take up so much room, 3. Construction time ie mounting on pcb with headers is slow compared to my pick and place machine 4. Arduino IDE is junk and takes up resources like timers that I want to use, that said I always made a killing on a person that used Arduino and asked I could make a 100 pcb or more as they did all the firmware and I just literally did a pcb design and charged for the project like I was doing it from scratch... Arduino is ok for a hobbyist but not for a commercial product... the raspberry pi has similar fate... cost is too high for mass production.

TOO SLOW.

It’s almost criminal that you don’t have many many more subscribers. Keep up the good work buddy.

Sweet guys ! Sweet project ! Keep going !

Arduino's microcontrollers (uC) are widely used by the industry, the same applies to all the circuitry you see in there. In terms of uC some boards are already quite old tech. Arduino is nothing special, in fact an Arduino board is probably within the complexity level of a third year engineering university project. Once you know how to design and build this stuff, why would you bother trying to fit your problems specs to an Arduino board when you can design the one you actually need? That's what pros do all the time; and I can tell you is not only more efficient and cost effective when millions of boards are produced, it is also a lot of fun. As for the software environment, it is a tinkering platform. I tried once and was like, this stuff is so below pro level, and just used the boards without all the simplistic software API and libraries. So basically, any recent graduate from any medium level university will probably never use this stuff for anything else beyond tinkering. It won't be used in widespread industrial applications because it is literally a toy. All that being said, they are quite handy tools and pretty much anyone uses them, including professionals.

You are correct. Production level programs normally are written in assembler using direct control of the microprocessor. The goal is to provide maximum efficiency and reliability, while also minimizing hardware cost. However, very very useful systems can be created using the Arduino Framework. It's just that they don't have the reliability of a product offered for sale. But I will tell you why Arduino/ESP and the other development boards are revolutionary. It's that they've opened up development to millions of new creative people. It's no longer in the realm of the giant, big business development lab. When you suddenly have millions of new electronics/robotics/IOT developers, world changing inventions are created.

Well one reason is warranty. Then reliability, you need to make a lot more protection circuits for arduino so you don't get a undefined state and need to use reset because the voltage for the arduino that is powering it goes slowly up to 3.3/5V and then the cpu can hang itself in an undefined state, as the base models are not shielded at all and that is only one issue. Another one is probably that big multimillion dollar companies can influence the laws a bit, so their products are need to be used. At least in my country.

Simply: because it wasn't designed to be used in industry. It was designed as a learning and prototyping platform hence simplicity, accesibility and fault tolerance over speed and specific function optimization.

Also true for HVAC. The main dealbreaker is that most programmable industrial or hvac controllers have a firmware with a programming language interpreter, and with how it is written, it is designed to allow you to easily change something in the program without causing a full-on service interruption. Arduino programming is only on the firmware level. Rewriting the firmware basically requires the CPU to stop executing commands. Not to mention that if you want to implement remote reprogramming or some other stuff, you need a platform for it, use or develop your own protocol, and then add stuff to the firmware. There's a reason why manufacturers like Allen-Bradley, Siemens, Delta Controls, etc... Aren't open source.

It's been said before; so I'll just echo the sentiment. Arduino, like Raspberry Pi, is wonderful for hobbyists and tinkering.

The answer is simple: "The conspiracy or collusion of Engineering Standards"

The big companies don't use arduino libraries for developping micro controllers, but you can develop professional applications with an ESP32 microcontroller, just like the big tech do it, if you use the esp-idf framework and you know what you're doing.

We do use it for quick prototyping all the time.

It's not even legal for industrial applications at least in Germany.

an ESP32 is not an Arduino.... you can use multiple languages to program both ESPs and Arduinos... youre not limited to Arduino IDE and arduino code... you could program it in complete C... or micropython..or many others... hell both can even be programmed at the machine code level.... ...what do you say about STM32s? that ARE used by industry.... SMH....programming languages do NOT DEFINE THE HARDWARE

Yeah, like others, didn't need to watch to know. Build better, cheaper just as a side-effect of having to design the solution. Even if something called for an Arduino, it'd be better just to get the AVR chips and build better, and still be compatible with the code. Great for education, though, which is what it was for. I've had dozens, but only bought one. The others I just built around the chip for toys like LEDs, printers in the old days, etc.

They are sometimes used for quick proof of concepts but they are way overpriced and underpowered for scale. Beyond that, just look at raspberry pi if you want to see the issues with industries using hobby grade stuff. The reason RPi is so expensive anymore is how man6 are picked up and used as the core compute unit in business applications. Other SBCs are cheaper and more industrial but for home gadget IoT use and time to market the RPi is front and center. But once places go to scale they look for better options.

A failure in industry could mean deaths, injuries, ecological issues and giant financial loses. You must be crazy to accept these risks to save few thousands dollars.

very good insights.

I use them (or similar products) for prototyping/MVP (fast time to market and Requirements finalization) before jumping to next version/real solution

Yes this seems to be the prevailing thought among engineers. Although I have replaced the environmental controller in our $250,000 greenhouse with a system that runs on an Arduino Nano. The Nano and all supporting components are attached to custom board with headers. The thinking was you could quickly replace these if they went bad. Over 4 growing seasons the only part that has failed is one $4.50 AHT temperature humidity breakout. The system has been rock solid 24/7 through power many power failures/blips (while our generator fires up) I code the Nano without a bootloader so it starts right up. I use a watchdog timer but have never recorded an instance. I have documented the build in this video and the blog linked in the video description. th-cam.com/video/XjPBXSxW4Mc/w-d-xo.html

Arduino is infinitely hackable.😊

Keep on going my dude. 👏
