3-)servo motor

4-)Battery

5-)Glue gun

6-)Bluettoh module

Step 2: Code

#include

#include

Servo myservo;

int bluetoothTx = 10;

int bluetoothRx = 11;

SoftwareSerial bluetooth(bluetoothTx, bluetoothRx);

void setup()

{

myservo.attach(9);

Serial.begin(9600);

bluetooth.begin(9600);

}

void loop()

{

if(bluetooth.available()> 0 )

{

int servopos = bluetooth.read();

Serial.println(servopos);

myservo.write(servopos);

}

}

Step 3: Build

tx pin to 10

rx pin to 11

servo to 9

battery + to vcn

battery- to gnd

bluetooth 5v to 5v; gnd to gnd

servo 5v to 5v; gnd to gnd

    Nicely done. :)

    Suggestions: Try to use a better camera from next time onwards and be a bit more descriptive when writing the steps. It will be helpful for everyone, especially those who are new to this circuit.

    I have also made this. Check it out.
