I have found a good use for an ATTiny85, which I have never used before. I notice that all of the programmers I've seen, including the Arduino ATTiny programming setup, seem to require that I program the chip essentially out-of-circuit, unlike a Nano, which I can plug into a breadboard circuit and still program in place.
So I am thinking of building a little board into which I socket an ATTiny, then passing the pins through the board so that the ATTiny pins can simultaneously be plugged into my breadboard. For programming, I thought I'd try passing the programming signals from an Arduino programmer through tri-state buffers mounted on my little socket board. When not programming, I'd set the buffer outputs to high impedance.
Does anybody out there know of good reason why this would not work? Thanks in advance for any thoughts, pro or con.
