[green]

OK I don't know if this is the right location for this question?
I've just purchased a UNO and was wondering if I can use other controllers on it?

Yes I did search this site and Google also......but I'm so green it's not even funny!

I think from what I've read that the 168 is a simple switch.
But I was looking at the Atmega8 and 88.
I want to make stand alone projects and 4k or 8k would be good enough.

How to I get a bootloader and the sketches on them?

If it's doable please educate me  :-[ I basically need a step-by-step, this is what you need to do, kind of approach.  I'm green I tell ya!

Just got my board one week ago and I can't put it down.
Lucky for me...my programmer friend also got one. And he is helping me a lot!

Thanks in advance for any help you can give me.  

Don't know if this is the right place for this?
Or even if this makes any sense.....

Is there a sketch or something that can check is a controller is working like it should?

Let me explain......I want to buy a bunch of atmega48, 88, 168 and 328 from my supplier. I'm not going to use the all at once (I will use them over time). So when I get them I would like to test them out? Are they all doing all they should? And if any are not 100% I can send them back.

Any help, guidance?
THanks
