DC Motor Control using XBee & Arduino in Proteus

DC Motor Control using XBee & Arduino in Proteus

• I have designed two Proteus Simulations for this project.
• The First Simulation is named as Remote Control while the second one is named as DC Motor Control.
• I am controlling the directions of these DC Motors from my Remote.
• So, let's first have a look at Remote section and then we will discuss the DC Motor Control.
• You can download both of these Proteus Simulations (explained below) and Arduino codes by clicking below button:

Remote Control

• Here's the overall circuit for Remote Control designed in Proteus ISIS:

• As you can see in the above figure that we have Arduino UNO which is used as a microcontroller and then we have XBee module which is used for RF communication and finally we have Keypad for sending commands.
• You have to download this XBee Library for Proteus in order to use this XBee module in Proteus.
• You will also need to download Arduino Library for Proteus because Proteus doesn't have Arduino in it.
• The Serial Monitor is used to have a look at all the commands.
• Now next thing we need to do is, we need to write code for our Arduino UNO.
• So, copy the below code and Get your Hex File from Arduino Software.

#include <Keypad.h>

const byte ROWS = 4; //four rows
const byte COLS = 4; //three columns
char keys[ROWS][COLS] = {
  {'7','8','9', '/'},
  {'4','5','6','x'},
  {'1','2','3','-'},
  {'*','0','#','+'}
};
byte rowPins[ROWS] = {13, 12, 11, 10}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {9, 8, 7, 6}; //connect to the column pinouts of the keypad

Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );

int KeyCheck = 0;

void setup() 
{
  Serial.begin(9600);   

}

void loop() 
{
  char key = keypad.getKey();
  
  if (key)
  {
    if(key == '1'){KeyCheck = 1; Serial.print("1");}
    if(key == '2'){KeyCheck = 1; Serial.print("2");}
    if(key == '3'){KeyCheck = 1; Serial.print("3");}
    
    if(key == '4'){KeyCheck = 1; Serial.print("4");}
    if(key == '5'){KeyCheck = 1; Serial.print("5");}
    if(key == '6'){KeyCheck = 1; Serial.print("6");}

    if(KeyCheck == 0){Serial.print(key);}
    KeyCheck = 0; 
  }

}

• The code is quite simple and doesn't need much explanation.
• First of all, I have initiated my Keypad and then I have started my Serial Port which is connected with XBee Module.
• In the Loop section, I am checking the key press and when any key is pressed our microcontroller sends a signal via XBee.
• Now let's have a look at the DC Motor Control Section.

DC Motor Control

• Here's the image of Proteus Simulation for DC Motor Control Section:

• We have already installed the XBee & Arduino Library for Proteus in the previous section.
• Here you need to install L298 Motor Driver Library for Proteus, which is not available in it.
• So here we have used two DC Motors, which are controlled with L298 Motor Driver.
• XBee is used to receive commands coming from Remote Control.
• Now use below code and get your hex file from Arduino Software:

int Motor1 = 7;
int Motor2 = 6;
int Motor3 = 5;
int Motor4 = 4;

int DataCheck = 0;

void setup() 
{
  Serial.begin(9600);
  pinMode(Motor1, OUTPUT);
  pinMode(Motor2, OUTPUT);
  pinMode(Motor3, OUTPUT);
  pinMode(Motor4, OUTPUT);
   
  digitalWrite(Motor1, HIGH);
  digitalWrite(Motor2, HIGH);
  digitalWrite(Motor3, HIGH);
  digitalWrite(Motor4, HIGH);

  Serial.print("This Arduino Code & Proteus simulation is designed by:");
  Serial.println();
  Serial.println("        www.TheEngineeringProjects.com");
  Serial.println();
  Serial.println();
  Serial.println();
   
}

void loop() 
{
  if(Serial.available())
  {
    char data = Serial.read();
    Serial.print(data);
    Serial.print("      ======== >      ");
    
    if(data == '1'){DataCheck = 1; digitalWrite(Motor2, LOW);digitalWrite(Motor1, HIGH); Serial.println("First Motor is moving in Clockwise Direction.");}
    if(data == '2'){DataCheck = 1; digitalWrite(Motor1, LOW);digitalWrite(Motor2, HIGH); Serial.println("First Motor is moving in Anti-Clockwise Direction.");}
    if(data == '3'){DataCheck = 1; digitalWrite(Motor1, LOW);digitalWrite(Motor2,  LOW); Serial.println("First Motor is Stopped");} 

    if(data == '4'){DataCheck = 1; digitalWrite(Motor3, LOW);digitalWrite(Motor4, HIGH); Serial.println("Second Motor is moving in Clockwise Direction.");}
    if(data == '5'){DataCheck = 1; digitalWrite(Motor4, LOW);digitalWrite(Motor3, HIGH); Serial.println("Second Motor is moving in Anti-Clockwise Direction.");}
    if(data == '6'){DataCheck = 1; digitalWrite(Motor3, LOW);digitalWrite(Motor4,  LOW); Serial.println("Second Motor is Stopped.");}

    if(DataCheck == 0){Serial.println("Invalid Command. Please Try Again !!! ");}
    Serial.println();
    DataCheck = 0;
  }

}

• In this code, I am receiving commands from my remote and then changing the direction of my DC Motors.
• When it will get '1', it will move the first motor in Clockwise Direction.
• When it will get '2', it will move the first motor in Anti-Clockwise Direction.
• When it will get '3', it will stop the first motor.
• When it will get '4', it will move the second motor in Anti-Clockwise Direction.
• When it will get '5', it will move the second motor in Clockwise Direction.
• When it will get '6', it will stop the second motor.
• It will say Invalid Commands on all other commands.
• Now let's have a look at its working & results.

Working & Results

• Now run both of your Simulations and if everything goes fine, then you will have something as shown in below figure:

• Now when you will press buttons from keypad then DC Motors will move accordingly.
• Here's an image where I have shown all the commands.
