“Hi! Heres my contribution to the long line of making programming shields to the Atmega family.
Im using to allmost ewery project of my own them ATtiny 84 (the 14 pins) & ATtiny85 (the 8 pins).
I got my kicks from a Instructable made by: Eric Brouwer
https://www.instructables.com/id/Arduino-UNO-as-At…
(many thanks to Eric for a superb instruction).
Im NOT going in for that how to do the programming/flashing itself in this ible.
I highly recommend You to first read the Erics Ible.”
