Arduino can be used to control a Servo motor, like the HiTEC HS-311 Standard Servo motor. There is a great tutorial on the Arduino site HERE.
The servo has 3 wires:
- yellow: control signal
- red: power (5v)
- black: ground/common
Code / Sketch:
// Sweep
// by BARRAGAN
// This example code is in the public domain.
#include <Servo.h>
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
}
void loop()
{
for(pos = 0; pos < 180; pos += 1) // goes from 0 degrees to 180 degrees
{ // in steps of 1 degree
myservo.write(pos); // tell servo to go to position in variable pos
delay(15); // waits 15ms for the servo to reach the position
}
for(pos = 180; pos>=1; pos-=1) // goes from 180 degrees to 0 degrees
{
myservo.write(pos); // tell servo to go to position in variable pos
delay(15); // waits 15ms for the servo to reach the position
}
}
