Guys help please!!,

I have bought a few atmega 48PA, 88PA, 168PA's from market. I am a newbie and really looking for help how to bootload and upload sketch into these chips :cold_sweat: . Luckily I do own a Arduino UNO having a atmega 328. But its not helping much.

It would be a great help if you please provide me hex files for 48PA, 88PA, 168PA .

Thanks in advance.
