Code Examples

### Example 1: Basic Motor Control using Arduino

In this example, we will demonstrate how to control the motor speed using an Arduino board.

Hardware Requirements:

Arduino Board (e.g., Arduino Uno)
 3.7V Coreless Motor With Propeller (7x16)
 Breadboard
 Jumper wires

Software Requirements:

Arduino IDE (version 1.8.x or higher)

Code:
```c++
const int motorPin = 9; // Pin 9 for PWM signal

void setup() {
  pinMode(motorPin, OUTPUT);
}

void loop() {
  // Set motor speed to 50% (128/255)
  analogWrite(motorPin, 128);
  delay(1000);

// Set motor speed to 100% (255/255)
  analogWrite(motorPin, 255);
  delay(1000);

// Stop the motor
  analogWrite(motorPin, 0);
  delay(1000);
}
```
Explanation:

In this example, we use the `analogWrite()` function to set the motor speed by generating a PWM (Pulse Width Modulation) signal on Pin 9. The motor speed is controlled by varying the duty cycle of the PWM signal.

### Example 2: Motor Control using Raspberry Pi (Python)

In this example, we will demonstrate how to control the motor speed using a Raspberry Pi and Python.

Hardware Requirements:

Raspberry Pi (any model)
 3.7V Coreless Motor With Propeller (7x16)
 Breadboard
 Jumper wires

Software Requirements:

Raspbian OS (version 10 or higher)
 Python 3.x

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

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

# Set up motor pin
motor_pin = 18
GPIO.setup(motor_pin, GPIO.OUT)

# Set motor speed to 50% (50/100)
pwm = GPIO.PWM(motor_pin, 50)
pwm.start(50)
time.sleep(1)

# Set motor speed to 100% (100/100)
pwm.ChangeDutyCycle(100)
time.sleep(1)

# Stop the motor
pwm.stop()
GPIO.cleanup()
```
Explanation:

In this example, we use the RPi.GPIO library to control the motor speed using PWM. We create a PWM object and set the duty cycle to control the motor speed.

Note: Make sure to use a suitable power supply and regulate the voltage to 3.7V to ensure the motor's safe operation. Also, adjust the PWM frequency and duty cycle according to your specific application requirements.
