okai. now im doing a waterfall display printer. its got im going to control fast solenoid valves. hmmm pin numbers can be made up ill change them. im gonna use a z8 microcontroller. or assembler code it doesnt matter.
more detailed ive got a picture i change it to binary picture (black and white) these values turn valves on/off. i haven't decided on the valves im testing a few so i don't have a schematic. for now im just putting in constant values to see if the valves can open close fast enough. im going to use a already built calculator microcontroller z8 board.
Is this by any chance a school project where you've done nothing and now have a deadline looming? I'm afraid the way you've described this projet makes it seem as though you have very little knowledge of what's needed.
When you get a controller running, you'll need precise control of timing, you'll need an interface circuit to get from the processor's voltage to the valves' voltage, and you'll obviously need the valves themselves, and they need to be fast enough to produce precise droplets. If you have some valves to test, you could do that without a processor, with a 555 timer for instance.
