I recently purchased multiple PowerHD1810MG Servo Motors but I have not been able to get them to complete a full 180 degree sweep. They come closer to around 160-170 and I got the same outcome when I attached a shield to the Arduino and connected an eternal battery source.
Below is the code I am using.
// Include the Servo library
#include <Servo.h>
// Declare the Servo pin
int servoPin = 9;
// Create a servo object
Servo Servo1;
void setup() {
// We need to attach the servo to the used pin number
Servo1.attach(servoPin);
}
void loop(){
// Make servo go to 0 degrees
Servo1.write(0);
delay(2000);
// Make servo go to 90 degrees
Servo1.write(90);
delay(2000);
// Make servo go to 180 degrees
Servo1.write(180);
delay(2000);
}
What other troubleshooting methods are recommended?
