Pin Configuration

RDS3115MG 15KG Large Torque 180 Degree Servo Motor with Brackets
Pin Description:
The RDS3115MG servo motor has a standard 3-pin connector, which is commonly used in most servo motors. The pins are labeled as VCC, GND, and SIG, and are explained below:
1. VCC (Red Wire):
Function: Power Supply
Description: This pin is used to connect the servo motor to a power source, typically a battery or a regulated power supply. The recommended voltage range for this servo motor is 4.8V to 7.2V.
Connection: Connect the VCC pin to a positive voltage source (e.g., 5V or 6V) using a red wire.
2. GND (Brown/Black Wire):
Function: Ground
Description: This pin is used to connect the servo motor to a common ground point, which is typically connected to the negative terminal of the power source.
Connection: Connect the GND pin to a common ground point (e.g., negative terminal of the power source) using a brown or black wire.
3. SIG (Yellow/White Wire):
Function: Signal
Description: This pin is used to receive control signals from a microcontroller or other control devices. The servo motor uses Pulse Width Modulation (PWM) signals to determine the desired position.
Connection: Connect the SIG pin to a digital output pin of a microcontroller or other control devices using a yellow or white wire.
Connection Structure:
To connect the RDS3115MG servo motor to a microcontroller or other control devices, follow this structure:
VCC (Red Wire) -> Power Source (e.g., 5V or 6V)
GND (Brown/Black Wire) -> Common Ground Point (e.g., negative terminal of the power source)
SIG (Yellow/White Wire) -> Digital Output Pin of Microcontroller or Control Device
Example Connection:
Assuming you are using an Arduino Uno board to control the servo motor:
VCC (Red Wire) -> 5V Pin on Arduino Uno
GND (Brown/Black Wire) -> GND Pin on Arduino Uno
SIG (Yellow/White Wire) -> Digital Pin 9 on Arduino Uno (or any other available digital output pin)
Remember to use the correct voltage and current rating for the power source, and ensure that the servo motor is properly connected to the control device before applying power.

Code Examples

### Example 1: Using an Arduino Board

In this example, we will use an Arduino board to control the RDS3115MG servo motor.

```cpp
#include <Servo.h>

Servo myServo;  // Create a servo object

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

void loop() {
  myServo.write(0);  // Set the servo to 0 degrees
  delay(1000);

myServo.write(90);  // Set the servo to 90 degrees
  delay(1000);

myServo.write(180);  // Set the servo to 180 degrees
  delay(1000);
}
```

### Example 2: Using a Raspberry Pi with Python

In this example, we will use a Raspberry Pi and Python to control the RDS3115MG servo motor.

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

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

# Set up the servo pin
servo_pin = 18
GPIO.setup(servo_pin, GPIO.OUT)

# Create a PWM object
pwm = GPIO.PWM(servo_pin, 50)

# Start the PWM
pwm.start(0)

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

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

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

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

Note: In the Raspberry Pi example, you need to install the RPi.GPIO library and configure the GPIO pins accordingly.

Important Safety Considerations

Ensure the power supply meets the motor's voltage and current requirements.
 Avoid overloading the motor, as it may lead to damage or failure.
 Keep the motor away from direct sunlight, moisture, and extreme temperatures.
