Hello, Arduino fans.
I’m goose in this area, but in my blondie head I have one big project. I can explain electrical, mechanical and other engineer sciences, but I’m little bit old to fully understand Arduino possibilities.
Tell me please, are possible with arduino controll such operations one by one and several times. First programm: Rinse
Water filling approx 5 till 10 liters together with motor working ;
Motor working approx 1 minute
Air supply aprox 2 till 3 minutes. Second program: Supplying, mixing and delivering. (if mixing just one time)
Styropor supplying 280 liters (we build volume dosation with 280 liters volume). Supplying will be with screw conveyor or with air ventilator;
Binder suplying 10 till 13kilos (especial tank for binder with pressure or weight sensor) Delivering will be via screw conveyor;
Mixer inlet opening (with servo motor) and mixer switching on;
Binder delivering to mixer. Styropor tank will be directly on mixer inlet and deliver with themself. Binder is two possibilities via screw conveyor or tank builder close to styropor tank and opening with sliding door.
Mixer inlet closing and water inlet opening.
Water volume adding aprox 9 till 11 liters and automatically stop after necessary water adding..
Mixing approx 60-90 seconds and after thet opening air inlet.
Air inlet approx 30 till 40 seconds.
Air inlet closing and air valve opening for pressure dropping. Third program with several cycles of programm above.
First cycle is numeber by number like above.
Second and next cycles is different because styropr and binder dosing is the same time with point 5 till 9. And then automatically start from point three. Fourth programm is half cycle. Fifth programm is quarter of cycle.
All engines switching on via relays or contactors. For water dosing we plan to use http://www.seeedstudio.com/depot/images/large/product/flowsensor_LRG.jpg and magnetic valve.
For air inlet we plan to use plan use manetic valve.
Much harder is with binder weight control and styropor volume control. Here I haven’t idea, yet.
All operations is planning to swith on with touchscreen display.
Is it possible all this make and control with one or several Arduino. And how hard is to make programm for that.
One more ir than necessary dose binder from 10 till 15 kilos per mix. And sure if necessary change water volume, too.
And wich type of sensors can be used for binder and styropor dosing.
And one more question is. Is it possible fix mixing counts and later print out in one document.
Uff, I hope not so much questions per one time. I can talk hour by hour about construction work, but here I'm blondie, like my hairs
"I’m goose in this area" What does that mean? I've never heard that before.
Arduino can do all that.
Fill out your requirements some, noting what votlage and currents you need to interface to things.
Uno has 20 IO pins, maybe that is enough, maybe you can get by with a shift register and transistors for higher current switching.
Thanks for answer.
I'm goose mean, than I don't understand from Arduino at this moment so much, how I need. This is old post soviet joke, just live 20 years in USSR and thinking is little bit different from other countries
Voltage, what will use for engines is 220V and 380V. I think than Arduino in this case work like contactor switch for engine starting and stopping. More harder for me is programm for that and understand what type of sensors use for styropor volume and binder weight control.
And what model of Arduino can control this operations.

Not so silly, like you think
I drive with car on the right side, like most of world
In Your country passenger is driver, but driver is passenger

Anyway, to answer your question - any of the Arduino boards is capable of doing what you ask.
The bigger boards will give you more IO channels and more memory to play with, so might be "easier".
You should look at your requirements more closely and try and work out just how many inputs and how many outputs you need, and what type - analog, digital, PWM, etc.
There are ways of expanding all the different inputs and outputs to any of the boards by adding extra external components, so it's all dependent on what you actually need.
Controlling of pumps and motors etc is usually a simple output->transistor->relay->motor combination, unless you need bidirectional motor control, when you will need to look in to H-bridges and such (the Arduino Motor Shield could be useful for that). Sensors can be more tricky, especially if you have lots of analog sensors.
For motor switching I think use Arduino relay shield, it switch contactors and contactors switch motors.
Inputs can be:
Water counter;
Binder weight control;
Styropor volume control
I don't know how count timers, or it don't count like inputs or outputs.
Output can be (if points below is 230V, than it can be controlled via relay shield):
Water magnetic valve (can be 12V or 230V by the choise);
Air inlet magnetic valve (can be 12V or 230V by the choise);
Motor control for binder suplying to weight;
Styropor suplying motor;
Servo engine for mixer cover;
magnetic valve to drop down the air pressure.
Mixer motor.
Sure Touchscreen display. and I think printer port. Which one of this is analog and which one is digital, mmmmm it little bit hard for me
How I understand, than Arduino can contro much much more, but I haven't so much knowledges in electronics, at the moment
I'l try to draw scheme for this big equipment and tomorrow put here
Arduino can turn things on and off though may need pieces in between to handle power.
Arduino can read sensors, many different kinds, determine positions/volumes/pressures/noise/etc, even know what colors of light a liquid may absorb to tell maybe what it is.
Arduino can perform calculations.
Arduino is an electrical circuit that can configure itself, replace many-many small parts.
Arduino can do all this amazingly fast, below the millisecond level.
Also;
Arduino is a software as well as hardware.
Arduino boards are development boards. Final products do not have to be on Arduino board at all and final chips can be from a wide selection from 8-pin ATtiny to more than 40-pin chips capable of very much.
What you want to do, you should be able to find a chip that can control the workings. If there is no Arduino board with that chip then don't worry, you can use the chip with the board or by itself after programming. And every year it seems, they make new chips.
When you are ready, visit the Atmel site and browse the application papers just to see possibilities.
