Can someone tell me if it's possible AND safe to use Atmel Studio with Arduino Starter Kit? I'm a newbie to firmware in general and I don't want to "brick" my Arduino Uno Microcontroller. I don't quite know if the micro controller has been programmed in read only or special memory to make it Arduino compatible and me messing with Atmel Studio could mess it up. In other words, I want to know I can get back to programming through the Arduino IDE and continue working on the projects in the starter kit book. I've done about half of them.
1) Can someone tell me if it's doable, safe and WHY? 2) Any hints or gotchas or examples on how to do it?
My motivation is that I'm taking a job as a C# Windows programmer but will be exposed (I believe) to AVR and Atmel Studio and wanted to get familiar with it by just playing a little bit. Arduino libraries seems to hide a lot of the messy details (such as setting a pin output) which is fine, but it would probably be good to do those messy details myself and be familiar with the actual tools they will use at work.
I have searched for a "tutorial for dummies" that says what settings to pick, etc. to no avail.
P.S. If the answer is NO WAY is it safe or desirable, perhaps a recommendation for an AVR development kit (cheaper is better!). Actually, this is probably not a bad idea anyhow. Many Thanks!
