MY arduino sketch can never be uploaded after some normal projects. İts about avrdude and theres a screendshot of it, i tried reconnecting, uploading drivers, resetting, even reinstalling the İDE. no help.
sometimes it also says this error message
sometimes it also says this error message
Please do not post images of errors. Click in the output pane, press CTRL+A (select all) and CTRL+C (copy) or use the"copy error messages"button; next paste (CTRL+V) in a post. Please use code tags when posting errors (or code).
Any chance that your sensor is connected to pins 0 and 1 of the Uno; that would explain the problem.
Are you indeed using an Uno or maybe an Uno R4 Minima/WiFi or an Uno WiFi Rev2?
Did you manage to upload in the past?
You're using IDE 2.3.2 but posted in the IDE 1.x section of the forum; please pay attention where you post your questions.
I've moved your topic to a section of the forum that is more suitable for upload problems.
it sometimes happens, i shutdown and reopen my pc now it can function, but it was werid why it happened. i use an arduino uno clone
thank you for the topic change, im new to arduino uno forums so i pretty make misatkes about topics
Sketch uses 3250 bytes (10%) of program storage space. Maximum is 32256 bytes.
Global variables use 202 bytes (9%) of dynamic memory, leaving 1846 bytes for local variables. Maximum is 2048 bytes.
avrdude: ser_open(): can't open device "\.\COM3": Eri�im engellendi.
Failed uploading: uploading error: exit status 1
why does it happen? it most of the time İDE has no problems uplaoding, but sometimes it just doesnt upload
Not sure but I think it means "Access denied". One reason can be that something else is using COM3.
There is a known issue for boards with FTDI serial-to-usb converter that can prevent uploads (see "Access is denied" error when uploading to board w/ FT232 USB chip with Serial Monitor/Plotter open · Issue #1783 · arduino/arduino-ide · GitHub) if you have serial monitor open when uploading; the IDE closes the port so the upload tool can use it and sometimes something in the process goes wrong.
I have seen this mentioned as well for boards with CH340 serial-to-usb converters (more than likely your clone uses the CH340).
The solution would be to close the serial monitor before uploading. It might not be serial monitor but another application that blocks the access. You can find it using Process Explorer; you need to download and install it. To find the program / process that keeps the port open, you can find instructions in Exit error status 1 on Arduino uno - #15 by ptillisch and some details for different sertial-to-usb adapters in Exit error status 1 on Arduino uno - #18 by sterretje.
