This SG90 360 degree Continuous Rotation Servo Motor is special among all the available servo motors because its operation is very different from that of a standard servo. As instead of going to a specified angle, this servo will be static at a 1.5ms pulse, a longer pulse gives forward rotation and a shorter pulse give backward rotation.
The MG995 Servo with metal gear can rotate approximately 180 degrees. The servo receives the PWM Signal from the Microcontroller like Arduino and processes it to rotate in the specified direction. The stall torque of the servo is 8.5 Kg f.cm at 4.8V.
