Program will not upload

I copied and pasted program CIRC-02 into the arduino file. I built the whole circuit and plugged it in, and pushed the upload button. The program won’t upload it just keeps saying, “uploading”. It’s been like this for a lil over 5 minutes now. Anyone have ideas?

Can we have some more information.

Which board? Where did you get it? (Link please) then we can verify the USB to serial chip.

Which OS?

Have you checked the drivers and that you are writing to the correct serial port?
