Okey. This is an old thread but I hope it's ok I keep it alive.
I just printed som parts for my blinds.
I use a stepper motor (28BYJ-48 with ULN2003 Driver board) and this sketch found in this thread.
The sketch is awesome.
To my quiestion.
I want to run 2 blinds at the same time from ONE node. Synchronized or maybe individual.
Is this possible?
There isn't any digital pins over for this when using button(s).
I think i saw someone using analog pin connected to the ULN2003 someware.
Is it possible to run 2 motors on one board?
Really hope somone can answer som of my question.
What modifications is needed in the sketch if this is possible.

You can use an I/O expander like an MCP23017 which is a 16 port expander or a 8 port expander. They're cheap. Keep in mind they consume 1 mAmp. I'm currently working on a product to overcome that power issue for a battery powered Node. Will try to post about it in a while

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

I have been working on a similar project last week. The mechanics and ´looks´ are the most difficult part for me.

@ton-rijnaard
Hi. This was a problem for me to. The reason is the library changed name and updates was made.
I use the library version 0.9.
I have like zero skills in arduino. If you use the old library the button will work with the sketch i posted a moth ago.
Looke here: https://github.com/JChristensen/JC_Button/releases
Maybe some of the other older releases will work. Don't remember why o choose V0.9
Look at 2.0.0, "This is a major release that is not backwards-compatible with previous releases." -

To answer my own question the stepper runs fine from the analog pins.
Next step is to find some intersted in the same thing and see if we could get the sketch adjusted to run two steppers.
I will try when i get some time but I guess I will have problem to clone the calibration and store-to-eerprom-part. -
@patchmaster This is my current curtain control sketch. I work with the development branch, so the syntax can be a little different.
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.

I've copied your sketch and have everything setup - however, I have eratic behaviour and a few questions:
void setup() { // setup buttons pinMode(buttonPin1, OUTPUT); stepper1.setMaxSpeed(2000.0); stepper1.setAcceleration(1000.0); //saveStateL(closedPositionEE, closedPosition) ; // INIT: save closed position in EEPROM closedPosition = loadStateL(closedPositionEE) ; // need to get last values from EEPROM and assume the current position is correct setPosition = loadStateL(setPositionEE) ; stepper1.setCurrentPosition(setPosition ); }//--(end setup )----
Should the pinMode on buttonPin1 actually be an INPUT?
-
Can you please describe how to go about calibrating the system?
-
Does the //saveStateL(closedPositionEE, closedPosition);
need uncommenting for one boot of the arduino and the blind closed - then the sketch re-uploading with it commented again?
Your help is greatly appreciated as I have a twitching motor and feel I'm almost there!

@adds666 What i can tell it was a long time since @AWI was active here.
I use this sketch with my first bild since a couple of days.
For me it works like a charm. But in my case I control the motor from analog pins just to test and it seems OK.
No problem with the button.
The only thing I don't like, is the calibration.
I my case, using this on a blind, when calibrating, first it goes down, then i press the button, the blind stops at once and change it's direction and goes up. But when i reach the top level and want to stop it and save the state, it stops slow and pass the point i pressed the button and then reverse to the right spot. Problem is, the blind can't go further because it is in the top position.
If it would be the other way around it wouldn't be a problem.
Maybe i have the motor one the "wrong" side of the blind but when it is down the "downkey" in my HA is greyed out.
When it i up the "upkey" it greyed out so that seems right.What is not working in your case?
What motor do you use? I use 28BYJ-48 with ULN2003 and had to setstepper1.setMaxSpeed(2000.0);tostepper1.setMaxSpeed(1000.0);because the motor "slipped" at a speed of 2000.
Like i wrote earlier in the thread I tried to figure out how to "dublicate" the sketch and ute it for two motors.
I really don't know where to start to get this done. It would be awesome to use one arduino with two blinds. -

Hi @xydix , glad to hear you have the sketch working properly. Do you have the pinmode as OUTPUT or did you change to input?
And do you still have the saveStateL(closedPositionEE, closedPosition); line commented out?
If I change the pinMode to input, I get the system powered up and connected to the mysensors gateway fine - serial print repeats 'Button Release'. If I short press the button, the system does nothing. If I hold the button for 3000ms serial print reads 'Button Long Press' and the motor turns - however If I let go of the button, the motor stop and system returns to its 'button release' state.
I'm not able to get the system in to calibration mode.

I am still in "testing mode".
I had some problems with the node, it stoped receiving messages but did always work with the button.
Yesterday i built a new node and uploaded the sketch and it seems to work better.
Here is the sketch i use, I changed the pin for the button due to missing digital pins on my pcb.
And I am back on using digital pins for the stepper driver for the same reason.
I greyed out buttonpin 2. I don't think it is needed.
I also greyed out the heartbeat-part as I had problems. Just for testing. Don't know if it is suitable when using Home Assistant./* 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.
