For another update:
Turns out it actually works :slight_smile:
Used a very simple bit of code to just blink pin 1 on the register.
Which actually blinks pin 1 on all three registers.

    digitalWrite(latchPin, LOW);
    delay(500);  
    shiftOut(dataPin, clockPin, MSBFIRST, 2);  
    digitalWrite(latchPin, HIGH);
    delay(500);
    digitalWrite(latchPin, LOW);
    delay(500);
    shiftOut(dataPin, clockPin, MSBFIRST, 0);
    digitalWrite(latchPin, HIGH);

So step 1 is done.
Just step 2 of controlling the registers seperately still baffles me.
If I shift them: shiftOut(dataPin, clockPin, MSBFIRST, (2 >> 8));
Nothing happens to pin 1 of the second shift register.

Hehe to be honest it is starting to piss me off because it can't be that hard right??
Anyone any tips??
