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

HELLO, I,hobbiest want to learn how to programme Attiny 85, I am trying to programme Attiny 85 on home made Uno Sheild to programme Attiny85 Above errors above is ruins my spirit.

A schematic diagram of your homemade Uno shield would be a first step.

What is the device signature that is reported. Invalid signatures often indicate a wiring error.

Which sketch are you using on the Uno (assuming that the shield is connected to an Uno). Arduino-as-ISP?

The above will help others to help you; I'm not familiar with ATtinys so can't advise further.

PS
This does not seen to be an IDE 1.x problem hence your topic was moved to a more suitable location on the forum.
