About this project

Hey all...

I am back with a new project.

I hope you guys like it.

In this project I made a noticeboard which is basically an Arduino noticeboard which uses a Bluetooth module and an android mobile to transmit data and display on LCD screen.

In this project I use an application in android device to transmit data.

You can watch the whole video and do subscribe my YouTube channel for more new projects.

In this project I used components like Arduino Uno, 16 X 2 LCD display, Bluetooth module, Potentiometer, Android device etc

Connections are as follows:

LCD display to Arduino

Vss = GND

Vdd = +5v

Vo to pot 10K variable pin

Rs= D12

Rw= GND

E =D11

D4 = D5

D5 = D4

D6 = D3

D7 = D2

A = pot 2nd leg to 220 ohm resistor end

K = Pot 1st leg

Bluetooth module to Arduino

Tx = Rx

Rx =Tx

Vcc = +5v

GND = GND

The final setup is shown below:

Download the app in android device and connect it with Bluetooth module.

Open the app and send data and it will shown to the display.

Thanks.

Subscribe my YouTube channel for sure.

Code

CodeC/C++

#include<LiquidCrystal.h>
LiquidCrystal lcd(12,11,5,4,3,2);
void setup() {
  // put your setup code here, to run once:
lcd.begin(16,2);
Serial.begin(9600);

}

void loop() {
if(Serial.available())
{
  delay(100);
  lcd.clear();
  while (Serial.available()> 0)
  {
    lcd.write(Serial.read());// put your main code here, to run repeatedly:
  }
}

}
