HI. Please help me. I have an arduino uno, andone day I tried to upload some code. it was taking a long time and a a minute later I got a error saying something about the programmer not responding. I changed the cable and it was still giving me the error. One minute before i tried to upload the code and it gave me the error it was working. The next day I tried and this time the reset button was not working and it gave me a different error:Sketch uses 924 bytes (2%) of program storage space. Maximum is 32256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

Problem uploading to board. See https://support.arduino.cc/hc/en-us/sections/360003198300 for suggestions.

Please help, note: I am not using original arduino.
update: i did the loop back test and well i do not have good news:( the arduino website said that if the arduino fails the test it is broken and it failed:( should i keep my arduino? oh and does anyone know what the cause is?
For boards with CH340 TTL-to-USB converter, the loopback test is non-conclusive. We only know that you have an Uno but not what the TTL-to-USB converter is.
Depends
That might depend on the project that you were last doing before it failed.
When you plug in your Arduino board, does the "TX" LED light up or flicker continuously? That would indicate that the Arduino is doing a lot of serial output that may interfere with an upload.
i have no idea what type of uno i have all i know is that it is a uno. The last project i did is where i connected a joystick to the i think anolog pins to use as a mouse but i did not have the pins to put it into the i think atmega mode or semething and then i tried to upload my previos code that works perfectly.oh and after the code failed i tried blink but no good.
Uninstall it from Windows, reboot and try again? Besides, even if a clone, shouldn't it still come up as "Arduino" in Device Manager? My Elegoo ones always do.
In that case, you can try to burn the bootloader using ICSP; you need another Arduino or a programmer for that. If that also fails, throw the board away.
I responded in several other topics and someone may think I am preaching bullsh*t, but please try with the shortest possible USB cable with a good shield. You may get surprised. Using just another USB cable does not guarantee anything if the other cable is not so "good" either. I repeat - use a short one - like 40cm or even less.
