Hi there, I am considering getting an Arduino Uno as a slave board to run my servos. I have servos and their voltages ranges 3.6-6V. I have a 9V wall power supply but I’m afraid if I pulled out of the VIN pin on the Arduino I would fry the servo because it’s 3.6-6V, yet if I pulled from the 5V it wouldn’t be enough. So which should I use? Thanks!
