wireless lcd display via bluetooth brands

Circuit diagram of the wireless LCD display via Bluetooth is shown in Fig. 1. It is built around Arduino Uno board along with a 16×2 alphanumeric LCD (LCD1), Bluetooth module (HC-05) and a preset (VR1).

HC-05 Bluetooth module has six pins out of which four (Vcc, GND, Rx and Tx) are used in this project. Power supply for the circuit can be from an adaptor (12V, 1A) or USB.

Arduino IDE is used for programming Arduino board. LCD’s library (#include ) is used, which is already available in the latest IDE’s library. Here, the baud rate or speed of serial communication is set to 9600. For serial communication, inbuilt functions such as serial.begin(), serial.available() and serial.readString() are used.

The PCB layout for the wireless LCD display is shown in Fig. 2 and its components layout in Fig. 3. After connecting the circuit on the PCB, follow the steps given below to test the project:

2. Open Arduino IDE. Select COM port from your computer’s Device Manager. Set baud rate to 9600. Compile and upload the code (LCD.ino) to Arduino board.

3. Connect the 12V power supply to the Arduino board. The LED in HC-05 Bluetooth module will blink continuously. This means Bluetooth module is working fine. The LCD will display ‘Welcome’ message. If not, adjust the preset by varying VR1 till you get clear text on LCD1.

4. Pair HC-05 module with your smartphone’s Bluetooth using 1234 as password. After getting paired, the LED on HC-05 module will blink intermittently instead of blinking continuously.

5. Open Bluetooth Terminal and pair it with HC-05 module. You will see ‘Connected’ on the app. Type a message and press Send. The message will get displayed on LCD1.

This project aims to control the LCD using wireless technology. This will serve as a base to build more amazing projects on home automation and many more automation projects.

The LCD have been powered by Arduino UNO (Board). It contains a code which uploaded to the board. And once it simulated you can connect with Bluetooth Module (HC-05) with you compatible device

Once code have been uploaded and Connected the Bluetooth and start Sending Command through app known asArduinoBluetoothControland start Sending Command you will be able to see that the desire Command which have been sent through app start"s displaying on LCD.

UsageThere is multiple Use of Project:-You can came to know how to use Bluetooth with Arduino.It is a very helpful project who are getting starting in home automation.If you are a beginner and want to control Arduino with Smartphone so you can do with the help of this.If you want to send message with in room or in hall but are not want to talk loudly then this project will help you.

Connection Of LCDConnect the First pin from the left of LCD (GNDpin) withGND pinof Arduino.Connect the Second pin from the left of LCD (VCC pin) withVCC pinof Arduino.Connect the Third pin from the left of LCD (V0 pin) withGND pinof Arduino.Connect the Fourth pin from the left of LCD (RS pin) with11 pinof Arduino.Connect the Fifth pin from the left of LCD (R/W pin) withGND pinof Arduino.Connect the Sixth pin from the left of LCD (E pin) with10 pinof Arduino.Connect the Eleventh pin from the left of LCD (D4 pin) with5 pinof Arduino.Connect the Twelveth pin from the left of LCD (D5 pin) with4 pinof Arduino.Connect the Thirteen pin from the left of LCD (D6 pin) with3 pinof Arduino.Connect the Fourteenth pin from the left of LCD (D7 pin) with2 pinof Arduino.Connect the Fifteenth pin from the left of LCD (5V pin) with 1 K Resistor with2 pinof Arduino.Connect the Last pin from the left of LCD (GND pin) withGND pinof Arduino.

Uploading and TestingCopy or download the code attached with the project.Don"t forgot to download the LiquidCrystal.h library fromDownload the app known as Arduino Bluetooth Control available on Play Store.to download.Build up Button to control LED using the app. To Watch video how to Build up button.Once complete setup you will able to control send command using your Device

Excellent Sound Quality and Noise Reduction: The wireless earphone features 13mm composite drivers, high fidelity drivers and a unique stereo design. At the same time, wireless bluetooth headset adopts ENC noise reduction technology and has built-in 4 high-definition microphones. Ambient noise is reduced by 80% while preserving 95% of audio for clearer, more detailed calls.

Long Battery and LCD Display: Bluetooth headphones provide 5 hours of playtime on a single charge (varies by volume level and audio content). The portable charging case provides an additional 25 hours of battery life for these wireless bluetooth earphones, giving you an excellent long-endurance experience. Besides, With LCD battery indicator, the remaining power or charging progress of the charging box is clear at a glance.

Lightweight Mini Design: The surface and angle of the wireless earbuds have been repeatedly polished and refined to achieve a balance between beauty and comfort and make it comfortable to wear. Weighing only 4g for a single wireless earbud, plus the semi-in-ear design could eliminate any feeling of occlusion or discomfort. The small charging case is very suitable for carrying.

Touch Operation and Voice Assistants: Play/pause music, change songs, volume +/-, answer/end calls, voice assistant and more with just a tap on the bluetooth headphones. Wireless bluetooth earphone support voice assistants so you can quickly get the information you need

Hi, guys!! I"m Sridhar Janardhanback with another ibles.Today I am going to teach you how to send data from mobile to Arduino and display using it an LCD.This is achieved by usingHC-05 Bluetooth module.

The Bluetooth module is used fortransmitting data wirelessly from the transmitter to receiver.The hc-05 module works on the same principle but on the different operation.let me explain the basic pins of the Bluetooth module

Interfacing an LCD to an Arduino is hectic as it has much connection and also spoils the beauty of the circuit by its ugly wire.To avoid these stuff I2Cis used.

it is sometime difficult to connect with bluetooth in ipad. keep trying for the connetion or change the bluetooth app. after this it will not work please let me now.0
