It's been a 4 day and my Arduino UNO port didn't show up.its normally show up like usual but for the past week it didn't show up the port.The LED is lit up.I use Windows and the cable is on the good condition.I tried many different thing.
The LED sketch is loaded at the factory. It works when power is applied. This indicates your Arduino UNO is working...
With your cable from your Arduino UNO inserted in an available USB port, start your Arduino IDE.
Can you tell us what you see when you use your IDE to select:
- PORT? You should see one of your USB ports available. If not, this is the problem.
- TOOLS? You should see "BOARD" near the bottom.
- TOOLS >> BOARD >> (what board has the dot?)
My interpretation of OP's problem is that the ON led is on, not that the blink sketch is working.
@albert97796, please describe the project that you were working on when the problem started? Anything with motors and/or voltages different from 5V?
What does Windows device manager think of your board?
Please provide a link to the exact board that you bought.
Arduino uno.Im sorry for replying this late
Devise manager didn't show up anything amd the project im currently on is password door and it worked perfectly before.The next week,i want to edit some part of my code and the port didn't show up.I'm really sorry for replying this late
Is the USB cable different to the one you were using when your UNO was working?
No,i use the same cable
Ok, so we can hopefully rule out a faulty USB cable or one of those charge only cables.
Does your PC play any sound when you plug in your UNO USB cable?
No,it doesn't
What is all connected; electromagnet or motor? How is it powered. Did you test your board without anything connected (except for USB)?
- Does the USB plug on the PC work with e.g. a mouse or phone (assuming that a phone does not use the same cable as the Uno)? If not, the problem is somewhere in the PC.
- If yes, the problem is either the cable, traces on the board or the TTL-to-USB converter. If you have another cable or another device (e.g. printer) that can use the same cable, test your cable with to exclude the cable. If that does not work, it's the cable.
- If that does not work, it's your board (traces or TTL-to-USB converter); it's more than likely the TTL-to-USB converter. Which TTL-to-USB converter is on the board (it's the chip closest to the USB port.
I think this might be the problem.Is there any solution to this?
There is but it's probably cheaper to get a new UNO board. Before going that route, what were the results of the suggestions by @sterretje in post #10.
I'm planning just to buy a new one.Which is better Arduino DIP or Arduino SMD
DIP or SMD does not really matter. Advantage of the DIP is that you can easily replace the main processor (328P) if you blow the it up.
It's the same processor, just packaged a different way. If you think you may damage the processor with future experiments, then I might suggest the DIP variant as you can easily swap out a for a new one. You need to have a way of installing the bootloader (another Arduino) if your replacement chip doesn't come with one pre-installed.
