Principle of Work:

A geared DC motor works by using a gear reduction system to convert the high-speed, low-torque output from the motor into a lower-speed, higher-torque output that is better suited for the intended task. The gears work by rotating the shaft at a slower speed while amplifying the amount of force (torque) being applied. This process allows the motor to provide more power to a load while also reducing the speed at which it is rotating. The gears used in a geared DC motor are typically made of metal and are precision-engineered to provide a precise reduction ratio and smooth operation. The combination of the motor and gears creates a system that can provide high levels of torque and power at a controlled speed, making it an ideal solution for a wide range of applications.

Code:  

Demonstration of how to control a DC motor using an Arduino. It includes the following functionalities:

1. Pin configuration: The code sets pin 9 as an output pin, which will be used to control the DC motor.
2. Loop function: The code turns the motor on for 3 seconds at full speed (255) and then off for another 3 seconds.
3. Speed Up and Down Function: This function increases the speed of the motor from 0 to 255 and then decreases the speed back to 0.
4. Serial Speed Function: This function allows you to set the speed of the motor by inputting a value from 0 to 255 through the Serial port.

const int motorPin = 9;

void setup()
{
  pinMode(motorPin, OUTPUT);
  Serial.begin(9600);
}


void loop()
{ 
  int onTime = 3000;
  int offTime = 3000;

  analogWrite(motorPin, 255); 
  delay(onTime);                
  analogWrite(motorPin, 0);  
  delay(offTime);               
}

void speedUpandDown()
{
  int speed;
  int delayTime = 20; 

  for(speed = 0; speed <= 255; speed++)
  {
    analogWrite(motorPin,speed);    
    delay(delayTime);               
  }
  for(speed = 255; speed >= 0; speed--)
  {
    analogWrite(motorPin,speed);    
    delay(delayTime);               
  }
}

void serialSpeed()
{
  int speed;

  Serial.println("Type a speed (0-255) into the box above,");
  Serial.println("then click [send] or press [return]");
  Serial.println();  

  while(true)  
  {
    while (Serial.available() > 0)
    {
      speed = Serial.parseInt();  
      speed = constrain(speed, 0, 255); 

      Serial.print("Setting speed to ");  
      Serial.println(speed);

      analogWrite(motorPin, speed);  
    }
  }
}  

The code sets pin 9 on the Arduino board as the output pin for the motor, using the following line: const int motorPin = 9;.

In the setup() function, the pin mode of motorPin is set to OUTPUT using pinMode(motorPin, OUTPUT);, and serial communication is initialized with Serial.begin(9600).

The loop() the function contains the main code that will run repeatedly. It uses the analogWrite() function to turn the motor on (full speed) for onTime milliseconds and then turn the motor off for offTime milliseconds. The analogWrite() the function takes two arguments: the pin number and a value between 0 and 255 that represents the duty cycle of the PWM signal applied to the pin. A value of 255 means 100% duty cycle, which means the pin is on for the full period of the PWM signal.

There are two other functions in the code: speedUpandDown() and serialSpeed(). speedUpandDown() increases the motor speed from 0 to 255 and then decreases it back to 0 in increments of 20 milliseconds using a for loop. serialSpeed() allows you to set the motor speed by entering a value between 0 and 255 into the serial monitor of the Arduino software. The function Serial.parseInt() is used to read the value entered in the serial monitor and constrain() is used to ensure that the speed value is within the range of 0 to 255. The speed value is then passed to the analogWrite() function to set the speed of the motor.
