Hello All,
I am looking for some guidance on how to make my project and hoping you experts can help. I want to have 9 arduinos and 8 stepper motors and 4 servor motors and 4 OLEDs and multiple LEDs working in one project which I need to be in a serial circuit.
It is a stationary project that I would just like to plug into the wall into one outlet. My understanding though is you should have power to the motors be seperate from the arduinos. This sounds to me then I would have to plug my project into 2 outlets. Is this true?
If not what would be some methods to make my project work with using one outlet?
All my motors or OLEDs are intened to be only 5V or less motors. I thought maybe 1 power brick converting AC to DC and providing 5 volts would be enough for everything. Not sure though. I dont want to use batteries. I would need too many.
I know this is vague info but I am just starting and looking for terms or tips
on what subjects I need to research to make something like this work using one outlet if thats possible.
Thanks for any ideas.

@casey
thanks. I am not looking for exact calculations but general info. But here is an example to work with and if you can get it working off 1 5 volt power source that would help me: Its one of Dronebotworkshop youtube videos.
TB6612FNG H-Bridge Motor Controller
Tell me how I could make motors run with one power supply for both motors and arduino. Assume the motors are 5volt motors not 6v. Assume I have a 5 V power block with me and thats all I have to get it working. The sketch is already uploaded.

I had a long set of info on finding power requirements, but decided, what the hay let's skip that 🙂
If you get something like a Mean Well PS that will supply 12v and @12a you should be safe. Then power the Arduinos off that or from lm2596 boards that are connected to the large PS. The same can be done for the servos as long as they are not driving a large load.
What kind os steppers are you using? Nema class (11, 17, 23?) or the little ones that look like clock motors? If the latter, then an lm2596 will do it. If a Nema, then drive it off the big PS.

at the moment for my own project I am planning on 8 superflat nema 23 stepper motors for (thats a 2.8 volt motor) and using 8 arduino nanos 1-per nema 23. Each arduino nano would have its own Adafruit (PID 3297) DRV8833 DC-Stepper Motor Driver for the motor drivers. What is used for other non stepper motors is undetermined. I have a superflat nema 23 now and waiting for the DRV883 in the mail and will hook up to my adruino mega for testing.
I wish I could use or find a higher voltage stepper motor but I need a superflat motor one so my options seem limited. Hopefully 2.8 volts is enough.
For the sake of discussion though I would like to focus on the youtube video example so I can get a handle on some of the principles of powering arduino and motor with only 5 volts power brick.
