Hi guys, I am currently facing a problem. So, I have a usb shield attached to an Arduino Uno and I have an external power supply of 5V. If I want to use the usb shield as an output source of voltage, how do I connect the wires to the pins?
There's not enough information in your post to know if the USB shield has a 5V output pin.
What is the connection for the 5V out ? (is it a screw terminal , a pin or what ?)
If it's an arduino shield whouldn't it automatically provide power to the arduino through the shield pins ?
I'm not following the reason for your question.
