I am a subscriber to Nuts and Volts magazine and they are currently tutoring a beginners course on the Arduino. This got me interested so I bought a uno r3 board.
I did their first lesson and it consisted of downloading the IDE, compiling the MyBlinky program, and then uploading it to the uno r3. I was successful at getting this done.
Now I have three questions about it.
With the Atmega 328 now loaded with the MyBlinky program could I move the processor over to a breadboard, make all the correct electrical connections, and have a standalone processor running the program?
I notice the uno r3 has a power jack on it. I am not sure of it's purpose. If I power it up through this jack will it run the MyBlinly program with no usb connection to my pc.
I have some new Atmega328s. Could I plug one of them into the uno r3 and download the bootloader program using the IDE?
Thanks for any help. Hopefully, I do not offend with too many questions on my first post.
