1.Introduction of servo
The working principle of the servo: the rotation speed and direction of the 360° building block servo can be controlled by PWM. The 500-1500us PWM controls the forward rotation of the servo. The smaller the value, the greater the rotation speed; the 1500-2500us PWM controls the reverse rotation of the servo.
The greater the value, the greater the rotation speed. 1500us PWM is to control the servo to stop.
Before using the building block servo to build the building block shape, you must calibrate the angle of the servo to determine the center position of the servo, because all the angles used in the modeling are not all 360°, so if the servo is not calibrated , which will easy to jam the servo after power-on, thereby damaging the servo.
