Application Notes

--------------------

The MG995 servo motor is suitable for high-speed applications, such as robotics, drones, and RC models.

The servo motor requires a dedicated servo motor controller or a microcontroller with a built-in servo motor library to operate.

The motor's operating voltage and speed can be adjusted by modifying the PWM signal frequency and pulse width.

The servo motor's rotation range can be limited by adjusting the mechanical stoppers on the motor shaft.

Safety Precautions

--------------------

Avoid overloading the motor, which can cause overheating and damage.

Ensure proper heat dissipation to prevent overheating.

Use a suitable power supply that can provide a stable voltage and sufficient current.

Follow proper safety guidelines when working with electrical components and servo motors.

Pin Configuration

MG995 High Speed Servo Motor (180 Degree) Pinout Documentation
The MG995 High Speed Servo Motor is a popular choice for robotic and automation applications, offering high speed and precise control. This documentation provides a detailed explanation of the servo motor's pins and how to connect them.
Pinout Structure:
The MG995 servo motor has a 3-pin connector, with the following pin configuration:
Pin 1: VCC (Red Wire)
Function: Power supply voltage input
Description: This pin connects to the positive terminals of the power source, typically a battery or a DC power supply.
Voltage Range: 4.8V to 6.6V (recommended operating voltage: 5V)
Note: Ensure the power supply voltage is within the recommended range to avoid servo motor damage.
Pin 2: GND (Brown Wire)
Function: Ground connection
Description: This pin connects to the negative terminals of the power source, providing a return path for the current.
Note: A solid ground connection is essential for proper servo motor operation and to prevent electromagnetic interference (EMI).
Pin 3: SIGNAL (Orange or Yellow Wire)
Function: Pulse Width Modulation (PWM) signal input
Description: This pin receives the control signal from a microcontroller or a servo controller, which determines the servo motor's position and speed.
Signal Frequency: Typically 50 Hz (20 ms period)
Pulse Width Range: 0.5 ms to 2.4 ms (corresponding to 0 to 180 rotation)
Note: The PWM signal's pulse width and frequency should be within the recommended range to ensure proper servo motor operation.
Connection Structure:
To connect the MG995 servo motor to a microcontroller or servo controller, follow this structure:
1. VCC (Red Wire)
Connect to the positive terminal of the power source (e.g., VCC pin on an Arduino board)
2. GND (Brown Wire)
Connect to the negative terminal of the power source (e.g., GND pin on an Arduino board)
3. SIGNAL (Orange or Yellow Wire)
Connect to a digital output pin on the microcontroller or servo controller (e.g., D9 on an Arduino Uno)
Important Note:
When using a microcontroller or servo controller, ensure the output pin's voltage level matches the servo motor's recommended voltage range (4.8V to 6.6V).
Use a suitable servo motor driver or controller if the microcontroller's output pin cannot supply enough current to drive the servo motor.
Always follow proper wiring and soldering practices to prevent electrical shorts and damage to the servo motor or connected devices.
By following this pinout documentation and connection structure, you can successfully integrate the MG995 High Speed Servo Motor into your IoT or robotic project.

Code Examples

### Example 1: Basic Servo Control using Arduino

In this example, we will use the MG995 servo motor with an Arduino board to control its rotation.

```cpp
#include <Servo.h>

Servo myServo;  // create a servo object

void setup() {
  myServo.attach(9);  // attach the servo to digital pin 9
}

void loop() {
  myServo.write(90);  // set the servo to 90 degrees
  delay(1000);        // wait for 1 second

myServo.write(0);   // set the servo to 0 degrees
  delay(1000);        // wait for 1 second

myServo.write(180); // set the servo to 180 degrees
  delay(1000);        // wait for 1 second
}
```

### Example 2: Using MG995 with Raspberry Pi and Python

In this example, we will use the MG995 servo motor with a Raspberry Pi and Python to control its rotation using the RPi.GPIO library.

```python
import RPi.GPIO as GPIO
import time

# Set up GPIO mode
GPIO.setmode(GPIO.BCM)

# Set up servo pin as output
servo_pin = 17
GPIO.setup(servo_pin, GPIO.OUT)

# Set up PWM frequency
frequency = 50
pwm = GPIO.PWM(servo_pin, frequency)

# Set up initial duty cycle
duty_cycle = 7.5
pwm.start(duty_cycle)

try:
    while True:
        # Set servo to 0 degrees
        duty_cycle = 2.5
        pwm.ChangeDutyCycle(duty_cycle)
        time.sleep(1)

# Set servo to 90 degrees
        duty_cycle = 7.5
        pwm.ChangeDutyCycle(duty_cycle)
        time.sleep(1)

# Set servo to 180 degrees
        duty_cycle = 12.5
        pwm.ChangeDutyCycle(duty_cycle)
        time.sleep(1)

except KeyboardInterrupt:
    pwm.stop()
    GPIO.cleanup()
```

Note: In both examples, you may need to adjust the servo pin and frequency according to your specific setup. Additionally, the duty cycle values may vary depending on the specific servo motor and its characteristics.
