I want to use an Arduino to control 3 to 4 servos that are running at 6.5-7v (somewhere in between, using a adjustable voltage regulator). I want to know what the wiring will be like for that? If required, I can also use the required servo to power the arduino through Vin. I think that by doing that, I can also hook up the servo's ground to arduino ground???
I just need to know how the electrical wiring for this system will be if it is possible. If not, is there any alternative solution (other than running at 5v because i need all the torque the servo can give).
