14 | Servo

Servos are motors that rotate to specific angles based on a digital pulse width. Servos are commonly used for steering systems, windshield wipers and robotic manipulators. In this example we'll learn how to control the rotation of a servo using a dial on the front panel and then modify the code to create a windshield wiper.

Circuit Schematic



  • Open the LINX - Servo 1 Channel example from the LabVIEW Example Finder.

  • Select the DO channel connected to the servo.

  • Run the VI, then rotate the dial on the front panel to rotate the servo.

  • Modify the VI to automatically sweep the servo back and forth.
  • Use the a potentiometer to control the angle of the servo.

  • Create a temperature gauge using the servo to rotate a pointer over a cardboard gauge.
