Boy do i feel silly, but I assumed that I could write and download code to the 328 chip on the arduino, then put the chip on a breadboard, apply power, and the thing would run. But since a simple blink LED program does nothing, I fear that I have misunderstood the entire arduino concept, i.e., the arduino is not a development board, it must be used at run time as well. So to get a 328 to run standalone, i guess I need to find some other dev. environment?
Thanks for any advice.
