This activity will facilitate understanding of the following things: - Interfacing of servo motors - Controlling angle of the servos - Changing speed of the servo motor - Delays - Applications of servo motors .
Copy this code:
// Use and control of a servo motor.
// 资源导航
#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
}
