Hi, I am new to electronics and I have a problem. I have recently bought two 9g Tower Pro servo motors. when I try to run the sweep code, my servo just moves approximately 3-10 degrees every 1 second instead of large sweeping motions which the code was designed for. My laptop then makes a sound (that sounds like when I plug in a usb) every 1 second. I tried it with 2 servo and they react the same way. I have already made sure that the connections of the servo to the arduino uno are correct. I am looking forward to your reply! Thank you very much!
Please see the sweep code shown below:
#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
}
}
