I may actually have gotten something like that in one of the kits
Exactly. I’ll learn about the internal resistors.
Don’t think i would have thought about that, thanks.
I already know what speed they need to turn, so there’s that. The timer was a request from the wife when I started taking about replacing the rotisserie steppers she was using with something like this. I was trying to find ways to make it better, and that was just something she wanted.
All at the same speed is fine, all at the same time is not. Her first requirement was that if I were going to build a multi Turner that they NOT be all on or all off. My first plan was to use the bigger motor she had and just run a belt to all the pulleys, boom done. But if we have a motor for each cup, I have a plug for each cup. Looking back at this project, it would have been easier to just wire all the switches to one plug, in parallel or something, however it is in a house. But then she wouldn’t have the timer. And the motors would cost more (offset the arduino stuff, more or less).
I guess one set of control pound per driver is easy enough to solve by controlling the power instead, right? Run a relay to that side with some of the saved pins? It would simplify the sketch a little, and then she could have TEN going. Have to upgrade the power supply, lol.
Bottom line, this has turned out to be some great learning and a fun time, but probably not the most efficient use of either the time or the money. But I always knew it would go that way.
Sure seemed that way, so I came for help!
Sure can, as soon as I know what I’m putting in it!
And @dkj4linux…holy crap! I’ve noticed how torquey these little guys are and I read about all their applications, but that is NEXT LEVEL. Really really cool, man. I’ve got some extra Drv8825 drivers laying around, and I might crack one open just because they are so cheap.
