Problem with multiple relays and delays

hi friends which works for 3 motorized shutters and how Arduino thank you

@zrom69 is this a question or statement?

I'm sorry for my English, I'm French
I try to control node 3 and motorized shutters which card must be used aduino thank you
:smiley:

@zrom69 no worries.
I am using arduino Nano but others will work too. The Nano is small enough and easy to program (it has USB). The Pro Mini is also a good option, but needs extra programer (it has only serial connectors).
I am using those and all work very well:

In addition you need the relays - you either could build that yourself or use ready to use ones:

If you want to control shutters, you usually need 1 relay per direction. so for your 3 shutters it would be 6 relays. I am not sure if there are products out there, you could take one with 8 relays if you do have the space or make them yourself.

The code I posted above is "ready" for 3 shutters (up/down each) and manual control buttons on an Arduino Nano.
you need to connect the relays on digital pins 3/4 & 5/6 & 7/8 and the manual inputs on analog A0/A1, A2/A3, A4/A5 (note: pin 14 makes out of Analog A0, a digital D14)
Besides this, connect the radio and power and you should be ready to go.

Hi friends
thank you for your help I have try the code on Arduino pro mini touts the relay they work or even monument must change something in the code Arduino
I am newbie in Arduino
there is detection of door opening
thanks for the help

hi @parachutesj hi @all
i tried the sketch posted above. it works but my relay board is active low and the relays are on when they should be off. #define RELAY_ON 0 and #define RELAY_OFF 1 do not change the behavior. the relays stay on. do you have an idea what is happening? thx

@ihtgtwtd
change in the code in the routines shutters UP/DOWN/STOP

the parts

digitalWrite(RELAYxxx, HIGH);

HIGH to LOW and vice versa

thanks for the quick reply. I did what you suggested and the switches work the right way but when I reset the arduino all relay contacts turn on and stay on until I give a command. this is a major problem, it will destroy the shutter motor. i think there is no defined case when the arduino powers on.

@ihtgtwtd
put this into the setup routine within the "for"

digitalWrite (pin, HIGH);

e.g. like this:

 for (int sensor = 1, pin = RELAY_1; sensor <= NUMBER_OF_RELAYS; sensor++, pin++) {
    // Register all sensors to gw (they will be created as child devices)
    gw.present(sensor, S_COVER);
    // Then set relay pins in output mode
    pinMode(pin, OUTPUT);
    digitalWrite (pin, HIGH);

  }

@parachutesj
thank you very much. looks good now.
