SG90 servo wiring

You might be bit confused about wiring up your TowerPro SG90 but don't worry here is the solution.
The brown wire is ground (-) and the middle one seems like orange or red that's (+) vcc and yellow or kind of orange that's for data/signal.

You can try the sketch below or get it from Arduino site.

#include <Servo.h> Servo myservo;  // create servo object to control a servo // twelve servo objects can be created on most boards int pos = 0;    // variable to store the servo position void setup() {   myservo.attach(3);  // attaches the servo on pin 3 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(5);                       // waits 15ms for the servo to reach the position   }   for (pos = 180; pos >= 0; pos -= 1) { // goes from 180 degrees to 0 degrees     myservo.write(pos);              // tell servo to go to position in variable 'pos'     delay(5);                       // waits 15ms for the servo to reach the position   } }

Note: If you don't know what sg90 servo motor is, then her is a video for you to watch.

This was a very short post just to explain howto wire up the servo SG90 and a small testing sketch to try it out. I hope it helps you, if it does please don't forget to come back and leave comment. Thanks
