I usually use my Arduino as an ISP programmer.
Let's say I want to program the blink LED code to my ATmega328 with the bootloader already in it.
Can I just program it in the classical way and pull out the chip from the Arduino? Is there any problem doing like this? It sounds easier and quicker.
(I'm talking only about ATmega328 with the bootloader already in it, not ATtiny or other ATmega chips.)
