Hello, On an excellent (but now closed) old topic ( Powering servos and arduino ), I learned a safe way of using one unique power supply to both power my servos and my Arduino. Basically, the idea is to use a regulated power supply, with enough current (power), and a decoupling filter: [decoupler] …

Connect the 5V in to a 5V pin an GND to a GND pin as you suggest

Ok, I'll do that. Thanks.

Anyway, would that be the same if I connected the 5V to Arduino Vin?
