Arduino's in permanent projects?

retrolefty:
...
Then when all is tested I pop out the programmed 328p chip and build it into the permanent project adding what few support components the 328p needs to operate with, crystal some caps, a pull-up resistor, etc.
...

Hi,

do you have more information what are the needed components? (Or links?) And how do I start with a fresh 328p on the arduino?

best regards
Andreas
