MG996 Servo

Circuit

This diagram shows two servos connected. But the important principle is that it doesn't matter how many servos you are using. If you are using a high-powered metal gear servo then you must use the separate power supply supplied to to power the servos. They are 6V device so you should not use the 9V supply. Using the Arduino's 5V pin is also not to be recommended as the  Arduino cannot supply enough power. Note that there MUST be common ground between the separate power supply, the servo or servos and the Arduino (as illustrated).

Once you have wired up the circuit as shown below, you can use the standard servo tutorials sweep and knob.
