An error occurred while uploading the sketch.

Make sure you have the right port selected in the Arduino IDE's Tools > Port menu. Make sure you don't have anything connected to pins 0 and 1 of your Uno while doing the Upload.

skand_tripathi: i have a problem in uploading the sketch

Select the port of your Arduino from the Tools > Port menu. If that menu is grayed out or the port of your Arduino board is not shown then one of the following may be the cause:

  • You may need to install the driver for the USB-serial chip on your Arduino. Determine which chip is used on your Arduino and install the driver.
  • You may be using a charge-only or defective USB cable. Test your cable on another device to confirm that it works for data.
  • Using a USB 3.0 port on your computer may cause problems. Try a USB 2.0 port or use a USB 2.0 hub plugged into your USB 3.0 port. a

the error appeared after attempting to connect the Arduino to the intellij ide, I already reinstalled the arduino ide already reinstalled the software of the usb controller and nothing need help !!!

I have the same error, when I was testing it I found that it was the bluetooth module, for some reason if it is to the current to program my Arduino gave me that error, my solution was to program the Arduino UNO without a connected module and it worked.

@mike12345

Are you using USB 2.0 or 3.0 ports and cables as Arduinos can be very hit and miss with USB 3.0 ?

Changing cables and ports is always a first stop in troubleshooting.
