Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

Remove any connections to pins 0 and 1. These pins are used for communication with your computer, including uploads. Connecting anything to these pins can interfere with uploads.

Make sure you have the correct board selected from the Tools > Board menu.

Make sure you have selected the port of your Arduino board from the Tools > Port menu.

Sometimes the port will be labeled with the board name in the menu. Other times it will not. If you don’t know which port is your Arduino, you can find it like this:

  • Unplug your Arduino board from the computer.
  • Tools > Port
  • Note the ports, if any, listed in the menu.
  • Close the Tools menu
  • Plug your Arduino board into the computer.
  • Tools > Port - The new port listed in the menu is your Arduino board.

my same problem. i try with 2 different arduino board but problem uploding to uno board

my same problem. i try with 2 different arduino board but problem uploding to uno board

Please do this:

  • (In the Arduino IDE) File > Preferences
  • Uncheck the checkbox next to “Show verbose output during: compilation”
  • Check the checkbox next to "Show verbose output during: upload
  • Click “OK”
  • Sketch > Upload
  • After the upload fails, you’ll see a button on the right side of the orange bar “Copy error messages” (or the icon that looks like two pieces of paper at the top right corner of the black console window in the Arduino Web Editor). Click that button.
  • In a forum reply here, click on the reply field.
  • Click the </> button on the forum toolbar. This will add the forum’s code tags markup to your reply.
  • Press “Ctrl + V”. This will paste the upload output between the code tags.
  • Move the cursor outside of the code tags before you add any additional text to your reply.

avrdude done. Thank you.

Thanks, I wanted to be sure it really was the same error, rather than just a generic "Problem uploading to board", which could have many different causes.

Did you already try the things I mentioned above?

yes i try all these things

I need to know which USB to TTL serial adapter chip is used on your Uno. This is the black chip near the USB socket on the board. It should say either "MEGA16U2" or "CH340G" on top. Which one is it?

MEGA16U2

MY MODEL EXHIBITION DATE -31/01/20 OR 01/02/20 .PLEASE HELP ME

  • Disconnect power from the board.
  • Remove all connections and shields from the board.
  • Force the processor to remain in reset by connecting a jumper wire from the RESET to the GND pin.
  • Connect a jumper from the RX pin (Arduino pin 0) to the TX pin (Arduino pin 1).
  • Connect the board to your computer.
  • Select the port of your board from the Tools > Port menu.
  • Tools > Serial Monitor
  • Type some text into the input field at the top of the Serial Monitor window.
  • Press Enter. If the text you typed is shown in Serial Monitor’s output window, the loopback test passed. If the text was not shown, the loopback test failed.
  • Close Serial Monitor.
  • Disconnect the board from the computer.
  • Remove the two jumper wires.

There is a good chance that your board is permanently damaged. If you're really under such a tight deadline, the best thing may be to just get a new Arduino board. You can come back to trying to fix the problematic one after your exhibition is over.

I've deleted your other cross-post @Agastya25.

Cross-posting is against the rules of the forum. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend 15 minutes (or more) writing a detailed answer on this topic, without knowing that someone else already did the same in the other topic.

Repeated cross-posting will result in a suspension from the forum.

In the future, please take some time to pick the forum board that best suits the topic of your question and then only post once to that forum board. This is basic forum etiquette, as explained in the sticky "How to use this forum - please read." post you will find at the top of every forum board. It contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

sorry and ok
