search mo datasheet ng pic na gagamitin mo sir.gamit ka ng transistor para mag drive sa relay.
dac-resistor-transistor-relay> i search mo ito sir para magka idea ka.

parehas lang ng switch ang relay sir,dapat may panggalingan ng 5v supply dapat.

ang relay po na nagawa ko 12v in pede na po ba un makapag out ng 5v? if my 5v regulator ako.

kung 12vdc ang source mo dapat ngang gumamit ng regulator.

vampire04, as an advice, try to document your projects with an schematic instead of layouts. may universal kasi kung schematic.
example, ako mismo, di ko alam kung anong transistor yan. di ko nga alam kung BJT (NPN or PNP)or Mosfet(n-channel or p-channel)...

malamang npn trani ginamit kasi nakakabit sa gnd. follow na lang yung mods na ginawa ko if you want 5v out

to be able to output a 5v from relay, you must have an existing 5V, relay is not responsible for making a 5v from 12v, but the regulator will do (LM7805).

i made a circuit for you.

i would like also to advise that when you are posting a diagram,
it is better to post the schematic diagram rather than the block diagram,
