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.

• Sparkfun Inventors Kit for LabVIEW Setup

• Sparkfun RedBoard
• 1x Servo

• LabVIEW
• NI-VISA
• LINX

• 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.
