سروو موتور SG92R

TowerPro Servo Motor – SG92R Micro
This is the latest version of the SG90, and features carbon fiber gears and control arms resulting in a massive 2.5kg torque, but just 9g of weight!
The SG92R can rotate approximately 180 degrees (90 in each direction), and works just like a standard servo!
The unit comes complete with 25cm wire and 3 pin ‘S’ type female header connector that fits most receivers, including Futaba, JR, GWS, Cirrus, Blue Bird, Blue Arrow, Corona, Berg, Spektrum and Hitec.
They work great with servo and ultrasonic control board, and other Raspberry Pi Motor Controllers.
They’re also great for the Arduino Motor Shield – or simply by wiring up Arduino with the Servo library.
You can use any servo code, hardware or library to control these servos, so it’s great for beginners who want to make stuff move without building a motor controller with feedback & gear box, especially since it will fit in small places.
Towerpro Servo’s comes with a selection of arms and hardware to get you set up nice and fast!

Wiring Guide

Orange: Signal
To control with an Arduino, we suggest connecting the orange control wire to pin 9 or 10 and using the Servo library included with the Arduino IDE (Example Sketch).
Position “0” (1.5ms pulse) is middle, “90” (~2ms pulse) is all the way to the right, “-90” (~1ms pulse) is all the way to the left.

Datasheet: SG92R

Example
Controlling servos on Arduino is very simple, since the Standard IDE provides the “servo.h” library, which allows you to simultaneously control up to 12 servos on Arduino Uno/Nano and up to 48 servos on Arduino Mega.
Among the typical examples to illustrate the operation of servos we have the Sketch “Sweep”, which performs a continuous sweep with the servo.
To do this, it increases the angle from 0 to 180º at a rate of 1º every 15ms, then performs the opposite operation from 180º to 0º, to finally restart the loop.

#include <Servo.h>

Servo myservo;  // crea el objeto servo

int pos = 0;    // posicion del servo

void setup() {
  myservo.attach(9);  // vincula el servo al pin digital 9
}

void loop() {
  //varia la posicion de 0 a 180, con esperas de 15ms
  for (pos = 0; pos <= 180; pos += 1) 
  {
    myservo.write(pos);              
    delay(15);                       
  }

  //varia la posicion de 180 a 0, con esperas de 15ms
  for (pos = 180; pos >= 0; pos -= 1) 
  {
    myservo.write(pos);              
    delay(15);                       
  }
}
