avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check.

With ATmega328P-PU I received this advice:
[code]
***failed;
avrdude: verification error, first mismatch at byte 0x0000
0xfd != 0x05
avrdude: verification error; content mismatch
My choices are:
Programmer: Arduino as ISP
Board: Arduino Duemilanove or Nano w/ ATmega328
Arduino 2:1.0.5 is a very outdated and non-standard version of the Arduino IDE. Try installing Arduino IDE 1.8.1 from http://www.arduino.cc/en/Main/Software
You can do that or you can leave the Arduino as ISP connected and do Sketch > Upload Using Programmer. This will remove the bootloader so if you later decide you want to do a standard upload via serial using the bootloader you will need to do Tools > Burn Bootloader first.

But how can I put this atmega328P execute blink in breadboard to test the upload and burn bootloader I just did?
