A video showing how a micro servo is tested.  Click on the image to watch the video.






The following code will turn a servo motor to 0 degrees, wait 1 second, then turn it to 90, wait one more second, turn it to 180, and then go back.

// 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 
void loop(){ 
   // Make servo go to 0 degrees 
   // Make servo go to 90 degrees 
   // Make servo go to 180 degrees
