I am trying to help my 11 year old son with his Arduino Uno. Version prior to Rev 3. When we try to run the blink sketch example in the software the RX and TX LEDs flash as we upload but the Pin 13 LED doesn't blink. We get the message at the bottom of the screen of the following photo. Thank you so much for your time. Electronics is something "Greek" to me. I just want to help my son who has a real interest. Thank you

There is no photo...

Can you attach one?

What operating system are you using? Have you loaded drivers for the Uno you have (available in the IDE download.)

You can copy and paste messages from the Arduino sketch window to the web browser. Putting the messages in the message is generally easier than taking a screenshot and uploading the picture.
