Timeline for When using Arduino Uno as ISP does "Yikes! Invalid device signature" mean a bad connection, bad config, or bad version of avrdude?

| Aug 14, 2014 at 15:20 | comment | added | Chris Stratton | This looks like an ISP<->target connection issue. Anything in your circuit which could be loading the lines? Are the ATtiny fuses still set for internal clock, or are you providing an external one? Are you sure you have all four signal wires and ground connected, and in the right order? Perhaps you should tack solder a setup just to verify it is not your hand-held method (though I've also used that) | |
| Aug 14, 2014 at 11:59 | comment | added | Yary | Phil, I did load the ArduinoISP sketch into the Uno before these steps, it succeeded, and I see the green "heartbeat" LED in pin 9 pulse. Gerben/user2973, I did try "-carduino", I will try "-c avrisp" next. Thanks. | |

When I upload from the arduino IDE and set the programmer to "Arduino as ISP" it uses -carduino not the stk500. Just try uploading the blink program to the attiny from the IDE. That way you can see the correct commandline at the bottom, if you enable "verbose output" in the settings.

Try setting the programmer to -c avrisp. I think you can program it at 1 MHz without problems.
