please solve this
We shouldn't be required to watch some long drawn out video just to help you.
Provide a complete description of the problem you're encountering.
Please post your full sketch. If possible you should always post code directly in the forum thread as text using code tags (</> button on the toolbar). This will make it easy for anyone to look at it, which will increase the likelihood of you getting help. If the sketch is longer than the forum will allow then it's ok to add it as an attachment. Don't put your code in some external file service like dropbox, etc. We shouldn't need to go to an external website just to help you. I do feel it's reasonable to post a link to code hosted on GitHub or similar code hosting sites since that's an platform specifically designed for this sort of thing
Please always do a Tools > Auto Format on your code before posting it. This will make it easier for you to spot bugs and make it easier for us to read. If you're using the Arduino Web Editor then you will not have access to this useful tool. I recommend using the standard Arduino IDE instead.
Provide a wiring schematic. You should attach and embed the image following these instructions:

ok...
Please give me a program
Program topics: Four LEDs, the first one will be off in 1 second, after which the rest will be on after 1 second.

Hi,
Welcome to the forum.
Please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Where is your current limit resistor in series with the LED?
I have no experience with the simulator, but the fact that the wire to the LED goes RED and the wire from the LED doesn't, must mean something.

Hi,
Do you have any parts to actually program a UNO?
Tom..
I got it. ..
To give you your valuable feedback
Many thanks
