    I'm pretty new to circuitry, but it would be great if someone could help me out a bit with this.

    My project is to trigger several cameras at the same time.
    For this I would like to use the Nano Arduino, shift registers and opto-isolators.
    I'v drawn up what I think might be the correct layout for everything below, although I'm not sure if it's correct.

    Any help with this would be greatly appreciated :)

    Hello,
    The circuit will not work, as the 1uF capacitor on the pins 12 of the 595's will block the pulses.

    Not quite block the pulses, but pass them off to ground and attenuate them below logic levels.
