Hi there, I'm kind of desperate. I'm completely begging to Arduino word, so this may be a stupid question, but how do i connect the Arduino to the computer?
I did it at first and upload the program in it and it works. but now i can not connect it to the PC (cant see the port)
1, i use the same cable
2, i use the same USB at same PC
i pressed 2× the reset button, but it does not work, i also try to shortage the button in order to simulate the press, but it has the same result. Just when i press it, it shows the red light (L) it goes dark after i release the button. The green light is on all the time (pwr)
Is it possible that i somehow destroyed the board? i don't see any damage, so i don't know.
i try to update all the drivers (Chinese ones) etc.
Which operating system? Does it recognise the board?
Which version of the IDE?
Yes, one can destroy electronics. Because you did not describe the project that you're working on (a schematic would help) it's difficult to judge if your project is the cause of the problem.
Damage to electronic components can be (and usually is) invisible.
W11; IDE 2.0.4
i set it as AVR board - nano (ATmega328P / old boot was working for me) on port COM6 and i upload on it just an easy program to blink with a diode which work (D2 - diode - resistor - GND). In 30 min when i connect it to the same USB on PC (USB chip CH340C) it does not show up. It is possible that i update something in the process.
The main problem is that now the board don't show in the PORT → i can see just the Bluetooth ports in the system
It probably meant, what does the Device Manager show for serial ports and USB info, etc. etc.
Also there is no response to my question about the USB cable - it's actually the leading cause of this problem. Post #3.
If you meant that the cable worked before, then you need to reveal what you have used the board for, prior to the failure. Was it connected to external circuits, if so what are they?
The problem for us is, we can't see the entire drama as it unfolded on your "stage" and although words can clarify what went on there, it can never fully cover all the possibilities. Not to impugn your particular skill level, but in general, many people can overlook important things that cause a failure, thus don't report it, thus we can't identify it (even though, it would sometimes take only a few seconds to spot it). Frequently, we see a thread go into dozens of speculative posts, before a simple photograph shows the detail, and 25 forum members who are reading it spot the issue simultaneously.
Having said that, parts fail, especially cheap ones. The bad news, the cheapness makes them more prone to failure, the good news, it's not expensive to replace.
My experience has been, that most of the component defects I've seen, have been visually obvious, sometimes for example, I reflow the tabs that hold the USB connector in place to improve on the effects of the factory soldering profile. In the factory (and I have worked in those), they have people (or robots) doing visual inspection because of that.
Another example of the subtlety of troubleshooting forum problems, we had a very similar post to yours a while ago. Everything was fine, circuit, power, software, etc. In the end, it came out that the experiments were being performed on a conductive workbench. The traces and pads on the board were intermittently shorting on the bench. I'm not saying you are doing this. I'm just saying, it's hard for us to really know. In point of fact, we don't yet have a picture of your board or setup.
so here is the board - this is still working (the original code i first upload for blinking with the LED)
I can not force it to restart with the button
It does not show up in ports on Arduino IDE
the visual of Arduino is ok, does not look like something burn up.
i try to restart it by bridging the restart button - also does not work.
So i find out the solution:
the USB port on Arduino get broken - the middle pin is pushed down and not connecting with the rest → this mean that all cables act like "power only"
the PC can not see it because the middle pin (data +) was not connected/ broken.
thanks all of you for the effort and replies
how it looks is on the last picture on this thread
