Can i use Arduino uno Vin port and its usb port simultaneously? Answered
Im fairly new to this. I need to have the arduino connected to my computer as it is receiving commands through a java script application.
the arduino then sends signals to a few servo's that i was going to power using an external battery. I was just wondering whether i then connect this battery to arduino's vin port (considering that is already powered on using the usb?).
I hope this makes sense.
