    This project will tell the LCD display temperature data transfer via bluetooth.Arduino-based system has a temperature sensor Lcd Screen Data Transfer will project the other system.Data from the system we can track the status of the LCD screen with instant aktıralarak system.

    Materials:

    • 2xArduino
    • Hc-05 Bluetooth Module
    • Hc-06 Bluetooth Module
    • LM35 Temperature Sensor

    In our project, you need to set the Bluetooth module AT commands will communicate primarily for two bluetooth module.

    Electronic Section:

    Transmitter Circuit:

    Receiver Circuit:

    Make connections, such as circuit in Fig.

    Software Part:
    Receiver Software:

    //Software development By Robimek – 2015

    #include <LiquidCrystal.h>
    LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
    #include <SoftwareSerial.h>
    #define BT_SERIAL_TX 6
    #define BT_SERIAL_RX 7
    SoftwareSerial BluetoothSerial(BT_SERIAL_TX, BT_SERIAL_RX);
    unsigned int temp= ' ';
    void setup()
    {
    Serial.begin(9600);
    lcd.begin(16, 2);
    lcd.print("temp:");
    BluetoothSerial.begin(9600);
    }
    void loop()
    {
    if (BluetoothSerial.available()>0){
    temp = BluetoothSerial.read();
    lcd.setCursor(0, 1);
    lcd.print(temp);
    lcd.print(" deg");
    delay(100);
    }
    }

     

    Transmitter Software:

    SoftwareSerial BluetoothSerial(BT_SERIAL_TX, BT_SERIAL_RX);
    unsigned int tempSensor = 0;
    unsigned int value;
    unsigned int temp;
    void setup()
    {
    Serial.begin(9600);
    BluetoothSerial.begin(9600);
    }
    void loop()
    {
    value= analogRead(tempSensor);
    temp= map(value, 0, 205, 0, 100);
    BluetoothSerial.write(temp);
    delay(100);
    }
