The atmega328p is brand-new without any bootload.
So could you guys tell me how can I wire the curcuit with LED and how can i program in order to make LED blinking with atmega 328p-AU.
In my case, the circuit was printed by silver ink(so it got some resistance, one pin line is around 5ohm).
Meanwhile, the power supply pin goes into pin4and6 in atmega at the same time. So that means if I plug in the power, the two pin (4 and 6) were powered. Is there any problem?
So how can I wire it up with LED? Do I need some extra resistor? I guess I need a AVRISP and I already got one
I attached the circuit pcb file. Hope you guys can take a look at it.thanks
Thanks.
Do I need some extra resistor?
Yes.
It seems odd to me you are asking such a question yet you can make a stand alone arduino. Have you included power supply decoupling capacitors.
A PCB layout is almost useless for telling what you have done.
As to the question.
See the blink sketch in the Arduino IDE.

Hi thanks for your reply.
I already made the board on paper with all the components mounted. Now I just plan to test the board whether it works or not(Such as make an external LED blinking).
My teacher request me to test the board(i think the main purpose is to test the Atmega 328P-au) on AVR studio4, but I have never programmed this before. And have no idea how to wire the circuit up. Do you have any suggestions?
Hope you can help me.

What an LED?
Anode of the LED to an output pin. Cathode of the LED to a 220R resistor. Other end of resistor to ground.
A red LED.
Yes still the same circuit as I just described.
