2PCS Mini Servo Motor 360 Degree Continuous Rotation w/Servo Horn Set (Arm, X, Wheel, Star) for RC Car Robot Helicopter Airplane Model

The signal terminal needs to be input with one 50 HZ square wave, then the duration of high level pulse, which is used to control signal cycle, can control speed and forward/backward rotation as well as stalling. The duration of high level corresponds to a speed. When high level is 1ms~1.5ms, servo rotates forward(the rotate speed is the fastest when it is 1ms, the higher the lower, servo will stop rotating when reaching 1.5ms). When high level is 1.5 ~2ms, the servo rotates backward(The servo stops rotating when reaching 1.5ms, when the duration is closer to 2ms, the closer, the faster. The backward rotation speed, the fastest when reaching 2ms) This servo carries meso-position adjustment potentiometer(it can only be seen by peeling off the outer cover and circuit board). We can set high level pulse at 1.5ms to observe that whether servo stops rotating. If it doesnt stop rotating, we keep adjusting the potentiometer until it does.
