[Solved] IDE not uploading code to Arduino uno

  1. Which operating system are you using.
  2. What is the serial-to-usb converter on the board (it's the chip closest to the USP port); e.g. 16U2 (original Uno, some clones) or CH340 (most clones) or ...
  3. Please enable verbose output during upload and disable verbose output during compilation. Perform an upload and post the complete result here using code tags as described in how-to-get-the-best-out-of-this-forum#use-code-tags.

There are two places that are easy to check; in the tools menu and in the tool bar under the menu.
