Thanks for the replies.

OK, let me clearly state the end condition of what hardware and what tools I wish to use, so you can guide me on the right path to my goal.

I have a Uno with a 328 chip. I've finished programming it. I want to take it out of the Uno and make a stand alone of it.

But my part supplier is out of 328's, but he as 88's in stock. My sketch is only 4k.

If he had 328's I would get those...... .60 cents more is not a big deal!
But he's out! Heck! Everybody's out!

As for the internal clock part. If it's simpler to keep it at 16mhz, I will (it's like .50 cents of part anyway) But my curious mind want's to know.

All I have is the Uno. So I was thinking of using it to put the bootloader on the 88 via a breadboard (with a crystal setup I guess, if it's simpler?)

Thanks again! Man learning is fun.  smiley

OK, so if I install the bootloader using the Arduino as an ISP/breadboard method. I should then be able to use any of these chips. Right?
How to I select what bootloader to install?

From what I can read the Atmega88 is not supported?
Is the Atmega48 supported?

One more "kinda" related question.
If i want to use the atmega chip outside the Uno board, but I want it to use it's internal clock. Do I need a special bootloader?

And if I install a bootloader on a chip using the Arduino as an ISP/breadboard method without a crystal. Will is be usable on my Uno running at 16mhz? Not sure if my question is clear?

So many questions?  :-[
Thanks for your time.

It's very reassuring to have a place like this. There is so much to's wonderful to have access to a forum like this. Full of knowledgeable folks, willing to help.  smiley

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 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?
