I just bought a Uno board & connected it to my laptop (Windows 7).  I installed the IDE environment, got the correct COM port (COM5).  Current situation:  Green light is on and yellow light is blinking once a second (I assume Blink is pre-installed.)  To test my system I changed the Blink sketch slightly.  I can see the lines:
1.  digitalWrite(13, HIGH);
2.  delay(1000);
3.  digitalWrite (13,LOW);
4.  delay(1000);

I tried to change Line 4 to delay(5000) to see if I could change the blinking sequence to 5 sec off.  I tried to upload the changed sketch, but keep getting an error message at the bottom saying
Invalid library found in C:\Users\........
and the light keeps blinking at the old rate (1 sec on/1 sec off.)
What am I doing wrong?  It's probably something simple, and I looked through the forum, but could not find a solution.  Any help is appreciated.  Thanks.


Why not show us the rest of the error?
Google the error that you did state and see what comes up.
