# Programming ATtiny84 using Arduino (Leonardo)

I am trying to program the ATtiny84 using an Arduino (Leonardo). I have seen this Shrinkify video. -and I have been following this Programming tutorial.

I have connected everything and am using Arduino 1.0.1 software. I uploaded ArduinoISP to the Arduino, selected "board" ATtiny84 (Internal 1 MHz clock), and selected "programmer" Arduino as ISP.

When I try to upload the blink example, I get this error:

Binary sketch size: 880 bytes (of a 8,192 byte maximum)

avrdude: please define PAGEL and BS2 signals in the configuration file for part ATtiny84

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

• What am I doing wrong?
• Should I upload by pressing "Upload" or "Upload using programmer"? (I have tried both - with same result)
• What does "use -F to override" mean?

Update:

I have now found that my problem is that Leonardo can not be used like this. I will investigate further.
