Hello i am a new arduino user. I have a working duemillanove arduino board with the atmega328p-pu .
I just bought two "Atmega168 20pu" chips without any bootloader so i made the following circuit into my breadboard. h..p://arduino.cc/en/Tutorial/ArduinoToBreadboard
With the above circuit i get :
avrdude: stk500_getsync(): not in sync: resp=0x15
after searching over the internet i have found that
this error is because of Auto Reset capabilities of Arduino
source :
h..p://laclefyoshi.blogspot.com/2011/01/note-of-caution-for-arduino-isp.html
Now after adding the 120 Ohm resistor i get this error messge :
avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check.
As board (tools options) i select "Arduino diecimila, duemillanove or nano w/ atmega 168". I am pretty sure that my circuit is correct.
What should i do ?
Thanks for your time !
