The servo is the traditional angle control driver and has been widely used in robot and other fields.In general,servo is driven by microcontroller system,but the driving effect of microcontroller system is not satisfactory for multiple servos.So,the Arduino,an open source control board,is used to output different pulse width signal to control the servo rotation angle,experiment showed that,this system realizes the angle control of servo,meets the requirement of angle control precision and provides a new way to drive servo.
