I have an Arduino board labeled UNO R3 I think is bad. To check I loaded the example “Blink” sketch that comes with the IDE (2.0). The sketch Verifies but will not Upload. The error message is:
“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.
avrdude: stk500_recv(): programmer is not responding
thru to
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xb4
Failed uploading: uploading error: exit status 1”
The program is: ArduinoISP
I also tried the loop test to verify board. When trying to send text to serial monitor it turned out the page wouldn’t provide a ‘send’ box to check status.
Almost certainly you have not selected the correct board in the Tools menu. That error message means that the programmer software is trying to connect to a board but the board is answring back with an unexpected ID byte.
FYI, writing in all caps is considered rude because it is the text equivalent of shouting.
Back to the subject at hand, just make sure you have Tools > Board > Arduino AVR Boards > Arduino Uno selected and that is the correct selection for the Uno R3 (the same board selection works for all revisions of the Arduino Uno board).
Make sure you have selected the port of your Arduino board from the Tools > Port menu in the Arduino IDE.
Sometimes the port will be labeled with the board name in the menu (e.g., Tools > Port > COM42 (Arduino Uno)). Other times it will not. If you don't know which port is your Arduino board, you can find it by doing this:
Unplug your Arduino board from the computer.
Select Tools > Port from the Arduino IDE menus.
Note the ports, if any, listed in the menu.
Close the Tools menu.
The ports list is only updated when the Tools menu is re-opened, so this step is essential.
Plug your Arduino board into the computer.
Select Tools > Port from the Arduino IDE menus. - The new port listed in the menu is the one for your Arduino board.
Com 3, labeled Active Management Tech. Tried- same problem. Checked Device Manager, it just lists Com Ports 1 and 3.
I'm curious about why when I try loop test I don't get a 'send' box to check when I open Serial Monitor: With no box to enter a response on page there can be no text to view.
You still did not answer the question which COM port appears/disappears when you connect/disconnect the board. You can also use windows device manager to find it.
Look, you are wasting everyone's time with your vague responses. Maybe you think you are saving time by not typing out detailed replies, but I can assure you that is not the case. When people make an earnest effort to provide the information requested by the helpers here, they usually have a solution within a matter of minutes. Yet you are coming up on a week now without any progress. That is on you. Maybe English is not your native language, but that is no excuse. Simply type out a high quality response in your native language and then run it through Google Translate.
I asked you 6 days ago to try a simple process that would have told us which port, if any, was the Arduino board. I still haven't gotten a straight answer about what the result was.
