Hi, can anyone help me program a circuit? I'm a beginner and I have no idea how to do it
Hi, can anyone help me program a circuit? I'm a beginner and I have no idea how to do it
TWhat kind of circuit?
KNope. Still in Shenzhen.
MIt will allow u to manage device settings, u can add ur wifi credentials there too, and u wont have to be uploading new code each time you doin it. you can update the wifi network name SSID and password directly from the dashboard there
MHow do I resolve this error ?
ADo you mean that I can change it through the word network or is there another way?

GThe circuit has a buzzer, an LED, 1 button (which is like a sensor), 1 button which is like a reset, an LCD screen, a switch and a Potentiometer. The project has to work as follows, as soon as I start simulating the project (which will be in Tinkercad) the word count and the zero below will appear on the LCD screen, as soon as I press the button that serves as a sensor, the counter it will show 1, ring the buzzer and turn on the LED at the same time and so on continuously, if for example I press the button 5 times, each time it is pressed it will appear on the LCD, depending on the time that the potentiometer marks and the buzzer and LED turn on together. The Potentiometer will serve as time in seconds to carry out the count, so for example if the Potentiometer has a delay of 4000 and I press the button, the counter will only show on the LCD after 4 seconds and the buzzer and the LED will also ring (the Potentiometer goes from 0 to 4000). When I press the switch down, it will show the Potentiometer information on the screen with the word Potentiometer at the top and the count in seconds below and when I move it up the switch will show the counter on the screen again. The other button will reset the counter
ZNice plan, where are you currently having issues?
MYh that network section is where u should enter ur wifi information
MOnce you enter the SSID which is ur network name and then password, click that configure button to save the changes thrn try to connect to the new network
GI don't really know how to program what I want to do, I needed someone to help me program
ZAh I see, I doubt you will find someone to help with that,
However if you are learning how to program and are stuck let us know we may be able to help.

GYes, I'm in the process, but I only know the basics, but I appreciate your attention
AThnx for help

Z@32bitSaviour @Ming Is yocto just
west
MIn essence - yes.
You still have a million scripts, they are just packaged nicely and called The Yocto Project!

ZAha that's insane that embedded linux is that huge, that the build tool is a project, as opposed to being shipped with a project.
MEmbedded Linux is that huge. A typical distribution contains thousands of files - but then a Linux system is meant to be for more heavyweight tasks.
MIf I wanted ‘small’ then I would go hand-rolled or just use something like zephyr.
MI think so. It is just scale that differs.
Zwell you want a good build tool rather than a small one
Zwhat is the scale difference would you say, I'm still looking at things very
baremetalI mean scale in terms of features, entirely based off, what each of them offers - yocto would be just more complex.
For example, I think it would take a lot to have layering in zephyr but is it even needed.
And look at the learning curve on yocto.

ZI know this has been explained before, but can you explain
layeringLayering is simply having groups of related build instructions bundled in a 'layer'. You can then stack those layers on top of each other, e.g:
You can then build up your final system by adding in layers that contain the useful stuff you need (and therefore also don't include the layers of non-useful stuff you don't need)
This allows for complex systems to be almost pieced together in a way that is manageable.

MThe scale is not clear cut.
For 'simple things' where for example you are 'just' reading sensor data and then either acting upon it to control something or pass that data upstream, a full blown Linux type system would probably be an overkill.
While I don't know RTOS's that well, but for more complex systems, where you may want to have task isolation (in Linux every task is isolated from each other, so that an issue in user-space with one task should not affect any other tasks) or if you just need more computational power, then Linux makes it easier, as the OS handles a lot of it for you.
The other things would be familiarity with the system (I'm always going to be biased towards Linux, as I 'think' in Linux and can see the solution faster in Linux) or if an essential library is only available for one particular OS.

MWhen you are building your bike each layer is a like a specific group of things that serve a distinct purpose (grouping things into a function), so a layer could be the engine or custom seats. All the layers stack up and you have your bike. Building from layering allows you to build (and easily modify) your bike. Swapping the engine would be as simple as replacing or modifying the engine layer. This modular system gives you flexibility to create what you need while making it easy to modify without complexity.
Zso in this kind of world you don't need to rebuild layers that have not changed. I.e my OS and Drivers havent changed but my application has changed so just use a cache for the former 2 and re build my application.
ZAlmost like releases in elixir, but that's a bundle as opposed to a build system.
MIn a Yocto Project - the caching actually happens at the recipe level. It is more like a
makeFor layers - think of them more as bundles of functionality.
I have a great CLI system and I now want to add a GUI. All I need to do is add a Graphical layer, say XFCE and I can then select which recipes from that layer I actually want to use in my project.
Or, I have a great system from a RaspberryPi but now I want to build it for an ODroid. All I need to do is swap my RaspberryPi layer for the ODroid layer - keeping all the other layers in place.

ZMiiiing, what in the world is a recipe. Is this like a list of dependecies and their versions?
MA Recipe is the instructions in a Yocto Project for the how tos:
- How to download the source
- How to configure the source
- How to compile the code
- How to install the resulting files into the final image
The collection of files that actually end up in the final image are then a
.package
ZMan I'm sorry this is becoming russian dolls. Is a package an executable then. Is this what a .deb is?
MIt is russian dolls!

WHi, I found this interesting project in github called "Auto Jobs Applier AI Hawk" It automates the job application process using AI, making it easier to apply to multiple jobs with less manual effort. It can help you streamline your job search and save a lot of time.

If you’re actively looking for jobs or just want to speed up the application process, i think you should give it a try

SHi everyone. Mark here. I'm an IoT Engineer. Enjoy the full lifecycle of Product Development. Thanks for the invite.
TWelcome, Mark 
AI did everything written but still the same error 
I have an arduino uno R4 wifi board. I want blynk ncp to work on it, but this error always appears and I don’t know what the solution is. Please help me.

WIf u did as they say it may be a path problem ,
Chek if the Blynk.NCP library is installed in the correct folder. It should be located in the libraries folder of your Arduino IDE directory (typically Documents/Arduino/libraries). And run the IDE as administrator

ULet's break down the issue into smaller steps. Have you succeeded to control and monitor Arduino Uno R4 Board from a Blynk dashboard (without Blynk.NCP)? Also, could you please tell us, why you think Blynk NCP library can solve your problem? If it's just about OTA, you wish to achieve because it's possible to update firmware, means changing wifi ssid and password without using Blynk.NCP via OTA. Please provide more background details.
AFrankly, I have not tried running the board on the Blynk platform only without Blynk NCP, and the reason I chose this library is the (find device nearby) feature, as it makes it easy for the user to change the Wi-Fi network with easy and quick steps.
