Arduino Uno or Programmer not responding

Development Tools IDE 1.x

An error keeps happening like below. Can anyone help me fix this problem?

avrdude done.  Thank you.

Failed uploading: uploading error: exit status 1

What do I do to successfully upload the code?

Your problem is normal select COM port correctly
or select the right arduino board

Along with checking your COM port and arduino board selection, you can take a look at this thread too: avrdude: stk500_recv(): programmer is not responding - #203 by kunj_sorathiya

  1. Did it ever work? If yes, what is the project that you're working on when it started failing?
  2. Which operating system (I suspect a Mac)?
  3. Which version of the IDE?
  4. Does the port disappear from the IDE when you disconnect the board? If not, it's not your Uno.
  5. Anything connected to pins 0 and 1? Disconnect that.
  6. Anything else connected to the Uno.
  7. Original Uno or clone? In case of clone, what is the ttl-to-usb converter? If your board does not use the CH340, post the result of the loopback test.
