Hi, recently I am trying to control 4 TowerPro MG995 servos by an Arduino UNO board but seems the current provided by the Arduino is not enough for such a number of servos. Can I apply external power supply to the motor directly by connecting them into a breadboard with only the signal cable connected to the Arduino digital pin?

Hi,
   Yes, but you will need to make sure they are all connected on a common ground with the Arduino. I also add a 1k current limiting resistor on the signal line but most say you don't need to.
