Motors for Rolling Shutters - Which is the Best Way to manage with Arduino ?

Using Arduino Sensors
1

Good Afternoon Guy,
I would like to implement into my new home "motors for rolling shutters" to manage with our friends Arduino. Right Now I'm using Arduino Mega 2560.

Could you tell me kindly what stuff are necessary and give me kindly some references for start ?

Thanks

I would prefer to keep it seperated and use relays.

Since the motors are outside in the moisture and corrosion using relays seems the only option.
Are they operated with normal switches ? You could use relays parallel to the switches.
Are there only two contacts per switch ? for up and down. And it automatically stops if it is fully up and down ?
If so, you need two relays per motor.

There are many relay boards and relay shields for the Arduino.

Solid State Relay is another option.

Use H-Bridge to allow one motor to go in both directions.
Add level-arm micro switches to detect whn end of travel is reached.
Or a stepper motor and keep track of how many steps were travelled to know when to stop.
Or a continouous servo and monitor the number of rotations made.
Lot of ways to get there.

We need to know what kind of motors.
DC or AC ?
Low voltage (like 24V) or mains voltage ?

I have such a motor of 24V DC, and I used a relay to control it with an Arduino. Because is was easier to glue a 5V relay next to the Arduino than using a power mosfet.

Thanks for the Information,
mainly in need to buy from zero ... I don't know which kind of model use ...

So in my project I'm using a 220V relays, 5V i turn on, to ground Ov turn off,

the relays is not a problems, the other stuff yes because i don't know from where start,

Could you give me kindly a list of items needed ?

Thanks 10000 for the support,
gnux

You haven't said how heavy of a load you are moving.
Big outdoor awning that goes up & down, or rolls up?
Inside window shutters of cloth to just block the sun?
Blind that open/close with a turning shaft?

If you have a link to what you want to control, that would help a lot.

Some brands have already the possibility to program something. I would not know how to connect the Arduino with those. Perhaps the Arduino can use a remote control from to control the shutters.

For example this, http://www.tucsonrollingshutters.com/tucson_rolling_shutters.htm
They use Somfy motors, and I think my motor is also a Somfy motor.

Any shutters with a remote control is a big security risk. You have to keep that in mind. Remote controls with IR and RF (like 433MHz) can be captured and played back.

My Idea is manage a rolling shutter for home with normal dimension for example:

height: 2 m
width: 2 m

maximum,

in attachment there is an example (just to show you approximately)

sorry i did a trivial question, please let me know if you need more information,

Thanks

Erdin thanks for the information,
the link that you have provide will ship in Italy Also ? do you know more or less the costs ?

This kind of rolling shutter motor that I've seen on the site use realays ? I've sent an email to the company also.

Thanks,
Gnux

I'm sure there are suppliers of good quality rolling shutters in your country.
I think you need local worksman to measure the dimensions and to install it. Perhaps you can talk with them (before buying) about connecting an Arduino.

I think that you have 120v Somfy motor. The ones that I am familiar with, have electric stops on the motor. You can set the top and bottom stops so the shutter does not over wrap. I am working on similar interior shades that are controlled from my android phone. I am using two relays spst. One for each motor direction. Using code to turn off one relay with 1/2 second delay before a relay can be energized. I have not looked at the H bridge referred to by someone else. The operational relay is only activated for less than 10 seconds. I have been agonizing over what relay to use and worry about the electric back flow from the motor when turned off. you can set the arduino pins on and off through wifi or bluetooth.
