@AWI Thanks. Why dont you increase the pulley size (larger pulley) that will increase the speed.
I found driving stepper motor to be bit more complicated than driving a DC motor. I picked the Geared motor basis the calculation using this calculator.
Since without rails pulling the curtains on a metal pipe needed more torque. Thus I chose 100 RPM to be a suitable fit.
Will share the Schematics and PCB layout files soon. I have already added the sketch for reference. Since I was testing I did not put the circuit in any housing. But will give some shape soon.
Also will be adding 3 buttons for Manual Control.

DC Motor, very interesting!
Do you have end stops? The sketch doesn't open for some reason...
Cheers

@barduino I tried downloading the code, it works. Anyways I am pasting the code below.
For end stops I have not yet decided. I had some Ideas of using Hall effect sensor on both ends and a small piece of magnet in the string to detect ends or Maybe use stop switches. Not sure but will have to try both and see which works the best.
I am yet to clean the code I have some debugging serial prints in code which will remove once finalized.

Sweet!
My girl has put this on my todolist...
But still have to get started, this is some nice reference for my new porject! -

I'll be posting my HW design and Code as part of Contest on openhardware.io

I'm just curious, maybe its the arduino IDE version or something.
I'm using 1.6.4 and I get this:
However opening with a text editor is fine:
Cheers
@barduino Seems like the IDE. Open any example MySensors Sketch. Delete the contents from sketch and copy paste from my sketch. I guess that should work.
Are you able to compile any other sketch in Arduino?
-
@AWI Are you able to share the sketch you used with the UL2003 driver board? I have tried to combine the MySensors servo sketch with other arduino only sketches utilizing the UL2003, but without luck. Thanks.

@patchmaster I used the relay sketch and modified it to my needs. Sorry but I dont have any sketch for ULN2003. :disappointed:

The Accelstepper library gives you all the abilities to slow start/stop with numerous kinds of steppers.
My sketch includes a calibration function (stored in EEPROM) so the you don't need end stop detection (a stepper knows where it is)/* PROJECT: MY Sensors curtain controller PROGRAMMER: AWI DATE: march 11, 2016 FILE: AWI stepper1.ino LICENSE: Public domain Hardware: ATMega328p board w/ NRF24l01 and MySensors 2.0 (Development) Special: uses AccelStepper library Summary: Curtain control with stepper motor.

@Tore-André-Rosander are you using the development branch? The errors seem to indicate that is the case.
@AWI Thank you, that helped :)
I now have it up and running.But how do i connect and use this with a controller (like Domoticz)?
I use an ESP gateway (from the dev branch) and the curtain node is connected and showing up in domoticz.
But how do i make domoticz send commands to the curtain node?All i get when adding the curtain node both as on/off button and blinds in domoticz is "unreconized" in the curtain serial monoitor.

@Tore-André-Rosander I have defined it as "Blinds Percentage" in Domoticz. This send the V_STATUS and V_PERCENTAGE messages where the node should respond to...

This is what i get in serial monitor when i use the "up" "down" buttons for blinds percentage in domoticz.

I have not written this sketch as a complete S_COVER implementation. Only the V_PERCENTAGE part (not V_UP/V_DOWN). If you define it in Domoticz as "Blinds percentage" (see my previous post) it will work. Sorry for the confusion.

@AWI Seems like my problem is with Domoticz itselfe.
I have the same problem as described in this post https://www.domoticz.com/forum/viewtopic.php?f=6&t=7748 -

I have the same problem as described in this post https://www.domoticz.com/forum/viewtopic.php?f=6&t=7748@Tore-André-Rosander You can probably solve it by deleting the sensor in Domoticz and let the sketch present itself as S_DIMMER (and use another sensor id)
