relay card problem
prejudice built board 8 relays 5v self powered, can not work despite having read forum few topics place sketch of proof have replaced since = b11111111 + + , leds instead of light result accentono give me hand card work??

on relay board pin 4 goes 74hct95 pins 12 , 13. think after send shiftout command pulse pin 4 high low. has low data appear on output drive relays. in source see variable given don't use in loop. use data didn't see define it. i'm kinda new arduino have been using avr assembler years.

here info nick using 74hc595 spi. has data on chip.
you have latch , enable output drive relays.
