A DC power supply is connected to the Arduino to provide power to all servos (set on 6v), and the voltage from the Arduino itself powers the flex sensors.


If 6v is being supplied to the external power plug on the arduino, what is the measured voltage on the arduino 5v pin?  There may be a significant voltage drop across the onboard regulator. If your code/sensor setup is causing a lot of constant servo movement commands, then your power supply may be inadequate to supply the needed current for five servos constantly being commanded to move.
