So I want to only have one plugin for my project (a robot arm). I am using the Arduino Uno which I know I need 7-12V to power and I am using a few servos that run using 4.8-6V. Is there a way I can use the same power supply to power all of these? I have quite a few power supplies, at the moment I am using 9V 0.6A for the Arduino and I've been told I need to use 5V 2A for the servos.
I thought maybe I could just put some resistors between the power and the servos but not the Arduino? Or would it be more advisable to use two separate power supplies and just connect the grounds? I could do this but I'd rather not have two separate plugs for my project.
Thanks in advance!
