avrdude: stk500_recv(): programmer is not responding Problem uploading to board.

I keep getting this message, while trying to upload a blink sketch to my Attiny 85.

I have downloaded the right files, and made sure all pins are wired correctly to my Arduino Mega 2560.

Any thoughts, what other things might be causing the problem?

Your help will surel

Are you sure it's wired correctly? SPI is on different pins on the Mega2560, and programming uses the SPI pins.

What error do you get? Turn on verbose uploads.

What did you select for programmer and port?

What core are you using? There are many cores that support the ATtiny x5 series, and they're not all the same.
