wireless lcd display via bluetooth supplier

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.

Whats app guys.. In this tutorial, we are going to make a wireless electronic notice board using arduino and bluetooth. you are going to make it step by step manner. This will help us in passing any message almost immediately without any delay just by sending a SMS which is better and more reliable than the old traditional way of passing the message on notice board. This proposed technology can be used in colleges many public places, malls or big buildings to enhance the security system and also make awareness of the emergency situations and avoid many dangers. Using Bluetooth module display the message onto the display board.

in serial Reception, i planned a text format... if you want to display the given text, we have to send text in such a way " #MESSAGE* " so that i can extract the text between # and *.

After switched ON the hardware, note the led on the bluetooth blinks good and the LCD displays the title with a scrolling to the Left. if this happens, you are working perfectly

Wireless Freedom: When you turn on the ignition, the car kit automatically connects to your Bluetooth-enabled phone so you can leave it in your pocket, brief case, purse, etc.

No Charging: Other handsfree devices like Bluetooth headsets and portable car kits require frequent charging but install car kits are powered by your vehicle"s battery

Universal Phone Compatibility: Works with all Bluetooth enabled cell phones by all manufacturers. Also compatible with future Bluetooth models so you can keep the same handsfree device when you change phones.

This functionality requires the use of software version 10.4.0.10 (Gihub) or newer and Lairds Summit Software stack for the 60-series modules: /wireless-modules/wifi-modules-bluetooth/summit-software-stack-60-series

MCS stands for Modulation Coding Scheme and is an industry metric index based on Wi-Fi connection parameters between a client and wireless access point. These parameters include modulation type, coding rate, spatial streams, channel width, and guard interval.
