MG995 Servo Motor Metal Gear
MG995 is a digital metal gear high torque servo for airplane, helicopter, RC-cars from 10 to 6-th scale truggy and monster and many RC model.
It is ideal for low torque and light weight projects.
They work with most electronic control cards with microcontrollers, such as Arduino, Nodemcu, Esp32, Pic’s and Raspberry Pi cards and others.

NOTE
1. Power the microcontroller and the servos separately, since the current of the servos is more than that supplied by a microcontroller.
2. The servomotor incorporates a controller that only allows rotation from 0° to 180° if the PWM pulse width is commanded from the microcontroller.
3. If you are using the servo tester it will be limited from 0° to 90°.
This servo does not incorporate a stop to mechanically define the rotation of the gears from 0° to 180°, so if it is rotated manually the servo will have continuous rotation without having a stop.

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);                       
  }
}
