There is a super-cheap stepper motor for very low-end projects: 28BYJ-48 You can buy a set of 5 from Amazon, with the motor-controller board that your Arduino or RaspberryPi can interface to, for $14.

An Arduino Nano is more than sufficient for this project, unless you want to get exotic for the trigger inputs, like voice-commands, Internet-controlled, etc.
You’ll need something that can keep a position so this would mean either a servo or a stepper motor. Both can be found cheaply at a hobby store or online. The servo would be easier to code imo but the stepper would be quieter and likely have a smoother operation. If you chose a stepper motor I would recommend these

Also, as a note, these are the stepper motors I picked up: https://www.amazon.com/gp/product/B01CP18J4A/ref=od_aui_detailpages01?ie=UTF8&psc=1
Thanks!
Would it be possible to use these motors/drivers with the NodeMCU?

I was thinking about getting the NodeMCU, that motor pack, and this conglomeration of parts to get started:

What do you think?
If you outgrow those simple servos, you may also want to check out small stepper motors. I have some that include a gearbox which reduce the rotation rate by 64x, so something like 4000 steps per rotation--and theoretically you can do smaller steps.
I've been playing with these, and they're good, but much more difficult to configure in code.

Since there are 4 coils, you need to individually flip them high and low, and if you do it wrong it will move the wrong way, still stutter and jump, or just sit still. But, if time isn't an problem...
Best of luck on your project.
28BYJs are cheap steppers that you can control using a few different arduino libraries.
5 of them for 13 bucks with controllers.

It's a single very small stepper motor:

Only other things connected are an IR receiver, a limit switch, a microphone, and might run it all through a sound shield.
Sorry for the crap video, but let me know if anyone is interested in bi-directional double stepper motor control script I wrote for these guys:

Edit: Just started learning python so I probably have some funky code haha
