Hello,
In the book "What’s a Microcontroller? Student Guide VERSION 2.2", page 117:

"WARNING
Use only a 9 V battery when your Parallax Standard Servo is connected to the BASIC
Stamp HomeWork Board. Do not use any kind of DC supply or “battery replacer” that
plugs into an AC outlet. Improper use of these devices can cause the activity not to
work, or even permanently damage the servo."

Why the damage to servo??icon9.png

Thanks!!

    Most servos run happily around 6 volts, if you had your servo power connected Vin, that would be(in your case) 9 volts. That may be enough to destroy the electronics in the servo.If you are using servos under any sort of load then your safest bet would be a separate power supply for the voltage and current needs of the servos.
    That also will eliminate any low voltage resets caused by the servos.
