Hello. I'm new to this forum and arduino.
Let me explain my problem:
Usb is driving servos even when external power supply
is not connected.
This is my setup:
Arduino nano is powered with 2s Li-po battery (+ to VIN, - to GND.
HV Servos are powered with the same battery. Servo signals are connected to digital pins on Arduino.
(+ on servos and VIN are all connected to + on battery and all grounds connected together)
It seems like there is 5v out on VIN when only USB is connected and this is what's driving my servos.
Do I have my servos and/or Arduino wired corectly?
