How to program Elegoo Uno R3?

spycatcher2k:
What does Elegoo say?
What does their advert say it is?
Why have you not just tried it!

Sorry,

I have tried uploading the sketch "blink" to the board using the setting for Arduino/Genuino Uno, but it doesn't work and gives me the message "Problem uploading to board see http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions. Elegoo say nothing about programming the board anywhere.
Thanks.
