I was able to upload code on arduino a while ago but now I am getting this error message:
Sketch uses 1022 bytes (3%) 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.

Welcome to the forum
More details please
Which Arduino board are you using ?
Does the PC create a COM port when you plug in the board ?
Can you see the COM port in Device Manager ?
Have you selected the current COM port and board in the IDE ?
If you are using a classic Nano board, which processor have you selected in the IDE and have you tried the alternative options ?
Is anything connected to pins 0 and 1 of the board ?
You didn't say, so let me guess.
Windows 11?
Nano clone?
I had this happening on a Nano (Atmega328PB) with the MCUdude's MiniCore
Some suggested to change the menu Tools->BaudRate from default to lower values. I picked 115200 and it worked.
Of course, it wasn't that simple, it took me a while to find out that having the AVR ISP connected would not allow uploading via serial.
At the same time, a similar Nano Atmega328PB board which somehow has the signature of the Atmega328P works fine with the regular AVR core and with the AVR ISP connected.
go figure
Thanks for your reply!
Arduino UNO
Yes ,COM 5.
YES , I can see it in device manager.
yes , Ive selected the board and COM.
Nothing is connected to pins 0,1.
Win 10
Arduino UNO
I am sorry, but i dont get that!
gpt is saying this:
In the official Arduino IDE 2.3.10, there is no Tools → BaudRate menu for upload speed on an Arduino Uno.
The only baud rate you can change is in the Serial Monitor, and that does not affect uploading.
Did you verify you are using a USB DATA cable, and not a USB POWER cable?
If plugging in the USB lead creates a COM port then @user_128 is using a data cable
Often, on my Windows computer, if I change the sketch or unplug/insert the USB cable, I must reset TOOLS >> BOARD >> AVR BOARD >> (my board) and TOOLS >> PORT >> (my port) between sketches, even when "board" or "port" are indicated, but grayed-out.
(assuming COM5 was valid at the last use of the IDE)
You described the Arduino board you are uploading to as "Uno". Something that can be confusing is there are multiple boards with "UNO" in their name. We need to be certain of exactly which one you have. The reason is that the problem might be caused by the IDE not being correctly configured for your specific board.
Please tell us which of the following boards you are attempting to upload to:
- UNO (R1, R2, R3) or Uno Mini
- This includes clone/derivative boards as long as they have the ATmega328P microcontroller.
- UNO Q
- UNO R4 Minima
- UNO R4 WiFi
- UNO WiFi
- UNO WiFi Rev2
- ...or something else?
If you aren't sure which one you have, you can provide a picture of the board or a link to the place you bought it from and we'll see if we can identify it.
the baud rate only appears if you are using the "mini core"
Yes , It is USB DATA CABLE, As, I told earlier my arduino was working fine and i was able to upload the code but all of a sudden, I dunno what happened and now it is giving this error :
"Programmer is not responding"
Please try this experiment and then report the results:
This procedure is not intended to solve the problem. The purpose is to gather more information.
- Connect the Arduino board to your computer with a USB cable.
- Press and release the button on the Arduino board that is marked "RESET".
Now please reply here on this forum topic with the answer to the following question:
- Did you see the "L" LED blink multiple times quickly immediately after you released the "RESET" button?
