I need help regarding soap and water dispenser using the same output hose

I need some help regarding a project on an automated soap and water dispenser using arduino. I intended on having soap and water dispensed from the same output with an interval of 20seconds after the soap have been dispensed first

Then you need to provide us with a great deal more information.

Links to datasheets for the valves would be useful.

And a description of the logic that the Arduino is expected to apply.

…R

You need a valve that can serve both inlets at the same time, not only switch between both.

I have worked on a similar project. It was coffee vending machine and I have to provide different liquid materials through a single opening.

So, it depends more on your mechanical structure than Arduino coding. You should design T shaped structure and add automatic Flow Valves. Control these valves using Arduino.
