Want Suggestion for modify auto washing machine code

I want to add manual mode where user has option to input to call different function like wash, spin, dry etc.If user has not given any input within prescribed time, loop will start as prescribed.

Welcome to the forum.
Before you continue, please first of all read the sticky, then fix your code so it doesn't contain those smilies, and while you're at it add the rest of the information about your project that we will need but which is missing.
Oh, wait, it seems you actually do know how to post code!

I see a mixed up mashup of attempts at timing. Some of the lifted code has the right end minus start calculation that is useless in the face of the rest of it.

No code tags and should know better, I guess I shouldn't waste time on this either.

So what does this code do, and how is it different from what you want it to do?

GoForSmoke · June 3, 2019, 9:42am

Where to start? Maybe the worst is the use of floating point to do timing.

Note that Arduino double is the same 32-bit crap precision floating point variable and that Arduino has no FPU.

Learn to do proper millis timing using unsigned integer variables. Do that with example sketches instead of trying to work it into this project and learn poorly at the same time. If you learn it for real, you won't want let alone need the delay() calls.

It just execute all function one by one. But , i want to interrupt the loop and wait for input from user to call specific function like dospin or wash.

I'm newbie here and don't know much about programming. I want to add manual mode so that user can call specific function before starting of void loop to do specific task and if no input given by user, program should go for loop.

This is what the do-many-things-at-once lesson is for. When a delay() is running, nothing else runs until it is done so no way for code to see a pin change from a button press.

Here is my favorite site for that lesson taught simply. You may think "turkey bacon" if pork is forbidden.

When you get that down you can add checks for leaks (take too long to fill, not stay full when should) and other problems.

Gammon Forum : Electronics : Microprocessors : How to do multiple things at once ... like cook bacon and eggs

When you get that down you can add checks for leaks (take too long to fill, not stay full when should) and other problems.

Thanks. I will try to learn from there.
