I understand connecting motor voltage directly to esp8266 can cause problems, but I shouldn't need 2 power sources. how does my desk fan only have 1 plug, but all the wiring diagrams show exterior motor voltage supply?
Can I plug into my esp8266 Vout? it actually produces 6V
Please post your own, correct, hand drawn circuit diagram, rather than someone else's.
I shouldn't need 2 power sources.
Perhaps, if you have studied and understand intermediate electrical system design concepts, and learned how to remove the nasty noise spikes and Arduino-resetting voltage drops that motors introduce into the power leads. Useful search term: "power supply decoupling".
Until then you are far better off powering motors and Arduinos separately, but don't forget to connect the grounds.
Post an annotated schematic, by the time you have it drawn you will have an idea of how the circuit works. Also obtain a copy of the Arduino Cookbook and you will find the bulk of your project in there.
What? it's exactly the same. This is a GENERAL QUESTION. Please don't comment on things if you don't understand.
I'm not a newbie and others can just see the schematic above.
But if you insist,
nope, didn't help!
After some research I found a voltage regulator is great for filtering power from various supplies before circuit components. I'm assuming because the added capacitors store the extra energy to level out any dips?
so then can I just add 2 to my circuit below to handle any problems? or is the problem between the esp signal and the driver?
I think the buck boost converter would be best.
Are there any current issues to look out for?
You need to filter the power to the MCU, not the motor.
The motor power supply should be chosen to handle at least twice the maximum expected motor current (e.g. for a brushed DC motor, the start/stall current).
From that fuzzy picture the bottom converter is shorted.
The voltage regulater in my circuit diagram shows a regulator between 12V plug and MCU. Not sure if you saw that
So I just need to check current supply?
I imagine that you think so, but no one could be sure what a white square labeled "V Converter" might actually be.
A hand drawn schematic with standard component designations and intelligible labels would be much more useful.
Forget my schematic drawing. The question is, is putting a voltage regulator the same thing as you said previously about filtering the power to the mcu.
I did not intend for this thread to be specific to an exact schematic. It's supposed to just be talking about the generality of powering a circuit board and a motor off the same plug.
