GLOWING 8 LEDS IN TIME INTERVAL

 

GLOWING 8 LEDS ON TIME INTERVAL

 Circuit :

CODE:

ORG 00H

MOV P0,#00H

MOV A, #0FEH

BACK: MOV P0,A

RLA

A_CALL DELAY

SIMP BACK

DELAY:MOV R2,#08H

LOOP2: MOV R1,#0FFH

LOOP1: MOV R0,#OFFH

LOOP:DJNZ R0,LOOP

DJNZ R1,LOOP1

DJNZ R2,LOOP2

RET

END

The code should be written in keil uvision software and hex code should be compiled and burned to 8051 microcontroller with program burner.

I have used here AT89C51 a microcontroller of  atmel company .

This way you can make a pattern of several leds glowing on a time interval and can use in decorations or for any signal sending device.

For any further assistance if required then comment below.
