I have an Arduino Uno platform and a servomotor TowerPro MG 996R. When i connect arduino via USB, the servomotor is working good with Servo sweep example. But when i connect Arduino via re-charge battery (9.6 V, 1000mA), servomotor working good for 3-4 tours, after that stops. And the Arduino's LED L, RX, TX is blinking. What is the problem?
I tried another smaller Servomotor and is working ok, with USB and Battery.
