I've an Arduino Nano to which a Micro Servo 9g is connected. The Arduino board and consequently the servo are powered by a USB powerbank connected to the board with a USB mini cable.
My question is: Is there a way to insert a power switch so I can turn on/off the board without plug/unplug the USB (that now is the way I use) ? I was thinking to cut the USB cable and work with the positive of it but if someone has an alternative or any tips I'd really appreciate it. Thanks!
EDIT: If is needed I could make a wiring diagram.
