Arduino USB Control Servo Motor
Use Arduino Board to control Servo Motor.
Hardware
1. Arduino Board or compatible Board.
2. USB Cable ( A to B Male/Male )
3. Servo Motor ( We use FUTABA Model S3003 or other)
Wiring Diagram
Use Arduino PWM Output pin 9

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
int motor = 0;
void setup()

Serial.begin(9600); // initialize serial:
myservo.attach(9); // attaches the servo on pin 9 to
the servo object

Connected OK");
Serial.print('\n');
}
void loop()
{
// if there's any serial available, read
it:
while
(Serial.available() > 0) {
// look for the next valid integer
in the incoming serial stream:
motor = Serial.parseInt();
// do it again:
pos = Serial.parseInt();
// look for the newline. That's the
end of your sentence:
if (Serial.read() == '\n') {
myservo.write(pos); // tell servo to go to
position in variable 'pos'
delay(15); // waits
15ms for the servo to reach the position
// print the three numbers in one
string as hexadecimal:
Serial.print("Data
Response : ");
Serial.print(motor, DEC);
Serial.print(pos, DEC);
}
}
}
//for(pos = 0; pos < 180; pos += 1) // goes from 0 degrees to 180 degrees
