Super easy questions [getting started]

I just got my Arduino starter pack today, set everything up (drivers, ect) and successfully got the Arduino to blink! :wink:

So here’s my question?

  1. I’m running it off of USB. When I am done playing with my Arduino, can I just unplug it? or is there a proper way to power it down (hit reset, or hold reset, then unplug or something)?

  2. Also I guess any sketches I write to it are always on the Arduino until I rewrite new sketches to it right? Just wanted to confirm.

Thanks, and Hi I’m new.

Welcome to rduino land :slight_smile:

Yes you can just unplug it, and the program remains until overwritten.

Thanks!

What pc are you using? I am having a lot of difficulty with Windows Vista (and XP but Vista is more important right now).

I’m on a MacBook Pro, OS X 10.5
It worked perfectly the first time for me, so can’t really give Vista advice. :-[

I’m using v0011 under Vista, it’s working ok… What king of problems are you having?

A Quick question before i get started. Can the ATmega168 chip be removed from the Diecimila to install in another project or is it part of this board.

I want to get started with micro controllers by making simple projects and building on that knowledge, but Im not sure if I want to keep using the same board.

Maybe someone can suggest a programmer I can use.

It can be removed. Check the forum for threads on minimalist Arduino’s, but the basic idea is you will want an external crystal/resonator, a regulated power supply, and a couple of filter capacitors for extra stability.

Several people have been going this route; programming the ATmega168 on the Arduino platform, then prying the chip out of the socket and sticking it somewhere else. Just remember, if you want fresh chips, you need to purchase ones with the bootloader pre-burned onto them. LadyAda, I know, sells pre-burnt chips. SparkFun, I believe, does not. Read the product description carefully when buying a new ATmega168 to replace the one you pried out.

A hundred people will give you a hundred answers. Me, I like the AVR family, and I was especially attracted to the smaller-footprint ATtinys. So the route I chose was ISP (In-System Programmer) and “minimalist target board” (basically, like the minimal Arduino above, only with the addition of a standard programming header).

You can actually use the Arduino itself as an ISP (there’s discussion of that in other threads here – sorry, don’t have time to search myself at moment). Personally, I chose one of LadyAda’s very cute “USBtinyISP” kits. So far, I’ve only gotten to “Hello World” but I found it pretty painless to set up and use. It’s still a USB cable, I can still write code on my laptop and load it into the chip from there. There’s even a nice environment (for PC users. Sigh). But it ain’t so bad writing code in text, then going into Terminal to fire up the software chain that does the actual burning.

Not as painless as Arduino, though! Consider the price and footprint (and the Arduino-compatible options) versus the time to learn how to use naked C in a command-line environment, and you might end up just using an Arduino or two after all.
