Standalone microcontroller

hi,

i've read lot of how-to's , tutorials on how load bootloader onto new chip, program second chip, etc. can't seem find answer simpler question: can take out working , programmed chip on arduino uno, , put working standalone product?

my sketch simple: virtual wall roomba. it's 1 ir led. ideally i'd want hook +5v power, , transistor drive led. understand, i'd need switch 8mhz internal clock, , should work minimal config. can't find guide how on prototype board itself, can move chip finalized "product."

my plan buy replacement atmega328p chip pre-loaded arduino uno bootloader, , use future projects.

it's got possible can find guide on how implement this?

thanks!

yes want simple really. once remove programmed chip install external circuit. circuit must have 16 mhz crystal resonator , provide +5vdc power , ground chips pins suitable voltage source. few bypass caps , pull-up resistor reset pin highly recommended. think if search on term arduino standalone should able find many examples of how accomplish goals.

good luck
