For a project I need to make my teacher advised me on using a servo from parallax
https://www.parallax.com/sites/default/files/downloads/900-00005-Standard-Servo-Product-Documentation-v2.2.pdf
According to the datasheet I shouldn't connect it to the Vdd and Vss from the microcontroller.
Would it be ok if I would it on the same power source (being my batteries) but my controller gets 5V from a regulator and my servo would be getting 7.2V directly from the batteries. (could also lower it to 6V)
