how can i get led on using assembly code

in my class we only have learned about ld, out and heard that we can turn led using only ld out

there are 8 leds at board and i have to turn 4 leds on

ORG 0000H
LD A,00000001B
OUT (00000011B),A
DEC A
LD A,00000010B
END

this is what we have done in class and i still dont get what i have to do...
we use z80

 

hi 111,
Welcome to AAC.
Are the 4 LED's connected to 4 separate Z80 pins, via a current limiting resistor.??
Did you write that Code fragment.?

all the LEDs are connected to different pins with resistor.
and that code is one of the code that professor explained us about turning light on

 

Hello,

The Z80 is a bare microprocessor.
https://en.wikipedia.org/wiki/Zilog_Z80
Do you use a board with a Z80 on it?
If so, what is there more on the board?
There must be likely some memory and rom on the board.

hi,
We need more information about the peripheral hardware that you are using with the Z80.
A circuit diagram. etc.
