Interfacing "Bluetooth Module" with Arduino Uno

 



Materials required-:

  • Arduino Uno Board
  • Bluetooth Module (JDY-30)
  • Breadboard
  • Led (as per your choice)
  • jumpers
  • Resistors (220 ohm ) 


Hey guys, This is our 10th project using "Arduino Uno" in this project I'm gonna show you how you can connect to a Bluetooth module and operate led . This is the similar concept used in "Home Automation" projects in upcoming posts I will show you how you can make your own Home automation system. If you guys have any doubts you can contact me through email or contact us form in menu.

If you want  me to make a project based on  your ideas just let me know in the comment section.


HAPPY LEARNING!

Arduino Code-:



int Roof_light=13;
int Left_Fan=12;
int left_Light=11;
int Night_Bulb=10;
int Right_light=9;
int Right_Fan=8;


void setup() 
{
Serial.begin(9600);           
pinMode (Roof_light, OUTPUT);
pinMode (Left_Fan, OUTPUT);
pinMode (left_Light, OUTPUT);
pinMode (Night_Bulb, OUTPUT);
pinMode (Right_light, OUTPUT);
pinMode (Right_Fan, OUTPUT);

}

void loop()

  {
    int c = Serial.parseInt();
    
   //Roof_light 
    if (c==1)
      {
       digitalWrite(Roof_light, HIGH);
       Serial.println("Roof_light ON");
      }
   else if(c==2)
      {
       digitalWrite(Roof_light, LOW);
       Serial.println("Roof_light OFF");
      }

   //Left_Fan 
   
   else if (c==3)
      {
       digitalWrite(Left_Fan, HIGH);
       Serial.println("Left_fan ON");
      }
   else if(c==4)
      {
       digitalWrite(Left_Fan,LOW);
       Serial.println("Left_Fan OFF");
      }
  
  //left_Light

    
   else if (c==5)
      {
       digitalWrite(left_Light,HIGH);
       Serial.println("left_Light ON");
      }
   else if(c==6)
      {
       digitalWrite(left_Light, LOW);
       Serial.println("left_Light OFF");
      }
  
  
  //Night_Bulb

   
   else if (c==7)
      {
       digitalWrite(Night_Bulb,HIGH);
       Serial.println("Night_Bulb ON");
      }
   else if(c==8)
      {
       digitalWrite(Night_Bulb, LOW);
       Serial.println("Night_Bulb OFF");
      }




//Right_light


    
   else if (c==9)
      {
       digitalWrite(Right_light,HIGH);
       Serial.println("Right_light ON");
      }
   else if(c==10)
      {
       digitalWrite(Right_light, LOW);
       Serial.println("Right_light OFF");
      }


//Right_Fan

    
   else if (c==11)
      {
       digitalWrite(Right_Fan,HIGH);
       Serial.println("Right_Fan ON");
      }
   else if(c==12)
      {
       digitalWrite(Right_Fan, LOW);
       Serial.println("Right_Fan OFF");
      }
  }
   


Now before uploading the code detach  Bluetooth module with Arduino and then upload the code after uploading the code you can attach the Bluetooth module . Next part is to download the application for Bluetooth module you can also use MIT inventor website where you can create your own application but here I have used "Serial Bluetooth Terminal " its easy to use application. what you all have to do is 
to choose correct value of button which is defined in the code you can also use your own configuration.


I know this code looks like home automation system code's and yeah ,it is actually I have made my home automation using this code and you can also build your own just by using this code what you all have to do is to use "Relay Module " (I have made my own relay module you can check previous post on this )in the place of led then digital pins will trig the relays which will act as a switch (you have to 
connect relays parallel to switch). 

If you don't wanna do this you can just stay tuned and in upcoming projects I will show you how you can make your own "Home  Automation Project".

Automatic Water Pumping System

Image
Here's a "Automatic Water pumping system" which controls the  water pump motor. The motor gets automatically switched on when water in tank falls below the lower limit . Similarly, its get switched off when the water is filled up( upper level ). This circuit is built with the help of 555 Timer IC Which is best and cheap.    Material required-: PCB Board 555 Timer IC 1k ohm Resistor x 2 220 ohm Resistor x 2 2 Pin Screw Terminal 5V Relay Battery(9v) Transistor (BC 547) Diode (IN4007) Led  Automatic Water pump Circuit-: If you guys have seen my previous post of relay module you must somewhat familiar with upper part of the circuit ,in which we just have to trigger the base pin of transistor to turn the relay on .Just like that, Here we are using output pin (3) of 555 IC to trig the base pin .   When the water level goes up and touch the pin 6 of 555 IC ,output of Pin 3 goes low(0) which switches off the motor. When the level goes below the low level ,that is pin 2 ...

Wireless Communication Between Two Arduino Board Using HC-05 Module

Image
In this post I will show you how you can communicate between two Arduino Boards using HC-05 Module. I am using Arduino IDE's version 1.8.7.  There are now newer modules that use a 3.0-20170601 firmware due to which module gives an error, But I will show you how you can fix this error. Just follow the exact same steps listed below and you will not get any error. Material Required-: PCB Board Arduino Uno x 2 Led Bluetooth Module(HC-05) x 2 Push Button (Switch) Resistor (1k ohm) Jumper Wire Connection for AT Mode -: 5V to Arduino 5V GND to Arduino GND TX to Arduino TX(D1) RX to Arduino RX(D0) Enable Pin to 5V Connections for AT Command Mode Step-1: Upload Blank code on Arduino Board. Step-2: While connecting supply to module long press the "Key Button" situated above enable pin. Now, You will see a delay in flashing of HC-05 led, that's means you are successfully entered in AT Command Mode. Step-3: Now open serial monitor . Remember that HC-05 requires Both "NL and ...
