I went around and round with this and finally tried a new chip and it worked. May have gotten damaged by bad instructions I was following by others. Follow this with a good chip and it "will" work!

Make sure you are using the correct (10uF) capacitor, it gives same error if you use wrong one or don't use at all.

I had the same problem with over 50 chips i got on JD - JOY BUY they had been packed just in a plastic bags no anti-static protection they all have Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check. and i am not trying to get a refund but i am not have much hope

Hello. Somehow it prevents nano from an unexpected reset or restart during programming.

Hello. This is same as nano. You connect same pinouts. 10,11,12,13, gnd and 5v+. The difference is only that you have to choose your correct atmega board type into software. Hope that helps u.

Mike Collins Yes

Thanks. I assumed you must have. I followed your excellent tutorial, and got my ATtiny programmed with a blink program. I have written an application in assembler, so is it possible to use Atmel Studio with this setup? Alternatively, how can I compile assembler programs with Arduino IDE?

+Mike Collins You should theoretically be able to use atmel studio with this setup. Because your Arduino is already programmed as an ISP, atmel will treat it as any normal off the shelf ISP and you will be able to upload code to the attiny. You can program assembly codes in Arduino, here's a link on how to do that. forum.arduino.cc/index.php?topic=37130.0 Good luck to you! -TT

Thanks a million, Tanner Tech. I'll look into that.

Yasyas Marangoz yes👍
