Kessil a350 dimming

Post by johniii »

Ok so I have three kessil a350 lights on my 220. They are just manual dimming. I was thinking about putting a stepper motor on each pot to simulate sunrise/sunset.

My question is it possible to set steppers to (x)steps every (y) minutes. Then reverse. I am using an arduino to get started and learn to code better. But would like to tie it into my RA+ after I figure it all out.

Yes :)
I'd love to see them working eventually!!!
You can go two ways.
You can use a regular stepper motor driver that requires synchronized pulses or you can go with an easydriver, which requires just standard pulses and a direction pin.

You could use for example:
Actinic and Daylight PWM ports to generate pulses for each of your stepper motor and use the ATO port to control the direction.
