Introduction: Servo Motor Control Via Bluetooth With Potentiometer

Picture of Servo Motor Control Via Bluetooth With Potentiometer

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.

Step 1: Materials:

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

Step 2: Transmitter Circuit:

Picture of 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:

Picture of 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.

Hi there!! thanks for the tutorial. But my (BluetoothSerial.available()>0) is not working, there is no serial communication between my Hc05 and my Hc06 please help.Thanks

siddiqui_saad (author)2017-03-30

similarly if i have to control 4 servos with 4 potentiometer via Bluetooth can i get a code please help

muhammadd46 (author)2016-09-15

hc 05 bluetooth whether it could have sent some data sensors to control robot ?
if it supports , can to do?

AnkitG27 (author)2016-03-05

I AM USING ARDUINO MEGA AND TWO HC05 MODULES TO CONTROL A SERVO USING POTENTIOMETER, BUT CANT ABLE TO DO IT..

ANY HELP??

sezgingul (author)2015-11-27

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

sezgingul (author)2015-11-27

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

John Tan峻 (author)2015-11-27

Is this also apply on 2 HC-06?

phamb587 (author)2015-11-22

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

sezgingul (author)2015-10-21

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.
