Controlling The Servo Motor By Using Bluetooth Module

Introduction

• In this article I will explain about controlling the servo motor by using the Bluetooth Module
• It will be controlled by using the Bluetooth module of the ON/OFF switch.

Parts Of Lists

• Arduino Mega 2560.
• Bluetooth
• Servo Motor
• Bread Board
• Hook Up wires

Connection

Step 1

Connect the Arduino Mega 2560 to Bluetooth Module,

• Connect the Vcc of the bluetooth to the 5v of the Arduino Mega 2560
• Connect the gnd of the bluetooth to the gnd of the Arduino Mega 2560
• Connect the Tx of the bluetooth to the RX of the Arduino Mega 2560
• Connect the Rx of the bluetooth to the TX of the Arduino Mega 2560

Step 2

Connect the ArduinoMega2560 To Servo Motor

• Connect the Vcc of the servo Motor to the 5v of the ArduinoMega2560
• Connect the gnd of the bluetooth to the Gnd of the ArduinoMega2560
• Connect the Vin of the bluetooth to the 09 of the ArduinoMega2560

Programming

#include Servo myservo;

// create servo object to control a servo
// a maximum of eight servo objects can be created

int pos = 0; // variable to store the servo position
int motor = 0;
void setup()
{
    Serial.begin(9600); // initialize serial:
    myservo.attach(9); // attaches the servo on pin 9 to the servo object
    Serial.print("Arduino control Servo Motor Connected OK");
    Serial.print('\n');
}
void loop()
{
    // if there's any serial available, read it:
    while (Serial.available() > 0)
    {
        // look for the next valid integer in the incoming serial stream:

        motor = Serial.parseInt();
        // do it again:
        pos = Serial.parseInt();
        // look for the newline. That's the end of your sentence:
        if (Serial.read() == '\n')
        {
            myservo.write(pos); // tell servo to go to position in variable 'pos'
            delay(15); // waits 15ms for the servo to reach the position

            // print the three numbers in one string as hexadecimal:
        }
    }
}

Explanation

• First download the bluetooth App in the Playstore in Google
• It can be applied for the buetooth connection then it will run in the servo motor.
• It will run in the ON/ OFF mode when the on button is touched the motor is ON.
• When the OFF BUTTON is touched the motor is OFF.
