    When I use the Arduino servo sweep program and use two servos one of them doesn't work correctly, it acts like its not getting enough power. This question seems to get asked alot but no one gives a definitive answer.

    Maybe it's not getting enough power.

    How are you powering both of these servos? Is it from the 5V from the Arduino? If so, are you powering the Arduino from a higher voltage source?

    The best option may be to use a separate, high power power supply for the servos which is connected to have a common ground (in this case negative) connection.

    Yes I was powering from my Arduino uno, I'll try that separate power supply and the common ground. Thank you for the reply.
