In this project, we will make the servo motor control with potentiometer via bluetooth.

Two will make the Arduino board via bluetooth wireless haberleştirerek control. Manages one of the modules for this (master) while the other managed (slaves) must be in mode. For both the master and the slave module settings, please click the link below.

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Materials:

  • 2 Number Arduino (Nano enough)
  • servo-motor
  • 10k potentiometer
  • Hc-05 Bluetooth Module
  • Hc-06 Bluetooth Module

Step 2: Transmitter Circuit:

Let's connect the signal pins to the analog potentiometer 0 pins.
Hc-05 Bluetooth module 4.p the tx pin, RX pin of the 3.pi to my tie.

Step 3: Receiver Circuit:

10.pin let's connect the servo signal to the pin.Hc-06 module TX to RX pin of the pin 4.pin 3.pin to my tie.

Step 4: Transmitter Software:

//Yazılım Geliştirme By Robimek – 2015

//Yazılım Lisans By Robimek

//www.robimek.com

#include <SoftwareSerial.h>

#define BT_SERIAL_TX 4

#define BT_SERIAL_RX 3

SoftwareSerial BluetoothSerial(BT_SERIAL_TX, BT_SERIAL_RX);

İnt potpin = A0;

int val;

void setup()

{

Serial.begin(9600);

BluetoothSerial.begin(9600);

}

void loop()

{

val = analogRead(potpin);

val = map(val, 0, 1023, 0, 179);

BluetoothSerial.print(val);

delay(100);

}

Step 5: Receiver Software:

//Yazılım Geliştirme By Robimek – 2015

//Yazılım Lisans By Robimek

//www.robimek.com

#include <SoftwareSerial.h>

#define BT_SERIAL_TX 4

#define BT_SERIAL_RX 3

SoftwareSerial BluetoothSerial(BT_SERIAL_TX, BT_SERIAL_RX);

#include <Servo.h>

Servo myservo;

Servo myservo;char val = ‘ ‘;

void setup()

{

Serial.begin(9600);

BluetoothSerial.begin(9600);

myservo.attach(10);

}

void loop()

{

if (BluetoothSerial.available()>0)

{
val = BluetoothSerial.read();

int servoAng = val – ‘0’;

myservo.write(servoAng);

}

}

Step 6: Finally

After installing the software, you can manage your power engine now wirelessly via a potentiometer.

    Hello, how do i "ramp" upp this configuration to handle bigger linear actuators like actuonix P16 for ex

    Kind regards

    I am using 2 Arduino UNO's with 2 HC05's and connecting the HC05 TX with 1 and RX with 0I on the Uno I have tried connecting them the other way round and connection them on the UNO TX to 10 RX to 11. But cannot get anything transmitted or received.
    Please help

    Question 5 months ago on Step 5

    Hi,
    I've been trying to this but with 3 servos to control.
    Can anyone help me with the sketch?
    Ive tried modifying it but there is always error.
    I am a newbie and have no experience on C+ language.

    Thanks

    phamb587 in Receiver Software change "char" to "int" and in transmitter software change "BluetoothSerial.print(val);" to "BluetoothSerial.write(val);"

    ohn Tan峻 2 HC-06 can not communicate. because only works in slave mode.

    one master to be able to do well in slave mode of communication must be other

    Hey Sezgingul!
    Im using Board Uno connecting (HC-05) as master. And the other is Board Mega connecting (HC-05) as slaver. I also apply your code in both Uno and Mega, but I change the pin tx and rx

    Uno

    #define BT_SERIAL_TX 10

    #define BT_SERIAL_RX 11

    Mega

    #define BT_SERIAL_TX 4

    #define BT_SERIAL_RX 3

    But nothing happens after I twist the potentiometer Can you give me some advices

    Thanks

    yes but can not using lm7805 to arduino power.

    I am surprised no has said anything about the amount of current the nano can supply versus the current the servo will require? I set up something similar with a servo turning a potentiometer. I used an LM7805 to provide the power to the servo.
