IR receiver reads 0


hi peoples :)

i couldn't find specified problem decided write new topic,
hopefully in right place.

so anyway, having hard time trying send ir code led receiver.
when using small remote came it, can read values in hex no problem.
but when try send value led shows value @ 0 , nothing happens.
sure receiver wired right reads remote hex.

the problem must in led emitter.
i have connected - ground in arduino , + output 4 (tried 5 same result).
there 330kohm resistor on + of led.

screenshot of code , serial window attached.

i'm new arduino please understand , forgive me if it's simple mistake :)
happy work on projects in future , welcome forums !

330k way led.

try 220 ohm.
make sure have cathode of led going gnd.
