I'm really new to Arduino and electronics DIY. I'm trying to power my Arduino Uno, Stepper Motor, and DFPlayer from a single source and I'm looking for some guidance. It works just fine thru the USB input from both my computer and a wall outlet, but will not power all 3 components thru the 12v JACK nor the Vin input with a 12V DC adapter wired into it. What's confusing is that I assume the 5v USB jack would supply less power than the 12v DC Jack, but I am proven incorrect in my assumption. Is there a way to power all 3 components thru a single power source that ISNT the USB Jack?
I have attached my schematic as well if that can help at all. Thanks in advance!
You need a separate 5V, 2 Amp supply for the motor & driver, when powered from USB motor is powered from computer USB, when powered from barrel jack or VIN, 5V comes from Arduino's 5V regulator which cannot supply that much current and will overheat & shutdown.

Post a link to the product page or data sheet for the motor.
You cannot safely power any motors or servos from the 5V output of the Arduino.
The motor is a DC5V 28BYJ-48. Here is the product page:

Is there ANY way to supply the required power for all of the components from a single source, and then split it to power the separate components? I'm trying to make it so I'm not having multiple power cords needed coming out of the toy. Thank you!!
