How To Test A Micro Server

// Include the Servo library
#include <Servo.h>
// Declare the Servo pin
int servoPin = 3;
// 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(1000);
   // Make servo go to 90 degrees
   Servo1.write(90);
   delay(1000);
   // Make servo go to 180 degrees
   Servo1.write(180);
   delay(1000);
}
