Alright. So I will use a 5V 10A power supply that I have, and connect it to the 5v pin and GND, and from that 5v pin I will connect it to the positive breadboard bus to power all my other modules.
The “backfeed” problem is just part of the UNO, Mega 2560 or Leonardo; the Nano incorporates a diode in the internal position which does prevent it. As I pointed out, you just need to disconnect (only) the 5 V pin when you connect to a PC via the USB port.
I will be storing my Arduino in a box that I don’t want to open every time I upload new code (I have an external usb port where I plug in a male to male usb from that port to my computer in order to upload new code. The other end of that external usb port is connected to the male end of the arduino cable ).
So will a standard diode work do I need something special?
Also, I am using a Movi Shield and one of it’s requirements are that it needs 7-16v that must be powered through the arduino.
Before you get started, you will need the following items to use your MOVI™ board:
*A 7V to 16V 500mA external power supply that powers MOVI™ through the Arduino board. The power consumption of both boards is just above what the USB port can provide. If you don’t have already one, this 9V adapter from Adafruit will work perfectly.
So could I use the 5V power supply, connect it to the 5v pin and still plug in a 9v Power supply in that barrel jack to power the [Movi Shield]?(MOVI - Audeme).
