Sweep

Sweeps the shaft of a RC servo motor back and forth across 180 degrees.

This example makes use of the Arduino servo library.

Hardware Required

  • Arduino Board
  • (1) Servo Motor
  • hook-up wire

Circuit

Sweep

Servo motors have three wires: power, ground, and signal. The power wire is typically red, and should be connected to the 5V pin on the Arduino board. The ground wire is typically black or brown and should be connected to a ground pin on the Arduino board. The signal pin is typically yellow, orange or white and should be connected to pin 9 on the Arduino board.

#include 

Servo myservo;  // create servo object to control a servo
                // a maximum of eight servo objects can be created

int pos = 0;    // variable to store the servo position

void setup()
{
  myservo.attach(9);  // attaches the servo on pin 9 to the servo object
}
