Arduino bluetooth scrolling text happy new year

What a great project idea!

To create a scrolling text display that says "Happy New Year" using an Arduino and Bluetooth, you'll need the following components:

  1. Arduino Board (e.g., Arduino Uno or Arduino Nano)
  2. Bluetooth Module (e.g., HC-05 or HC-06)
  3. LCD Display (e.g., 16x2 or 20x4 character LCD)
  4. Breadboard and jumper wires
  5. Power source (e.g., USB cable or batteries)

Here's a step-by-step guide to help you get started:

Hardware Setup

  1. Connect the Bluetooth module to the Arduino board:
    • VCC to Arduino's 5V pin
    • GND to Arduino's GND pin
    • TX to Arduino's digital pin 10 (or any other available digital pin)
    • RX to Arduino's digital pin 11 (or any other available digital pin)
  2. Connect the LCD display to the Arduino board:
    • VCC to Arduino's 5V pin
    • GND to Arduino's GND pin
    • SCL to Arduino's SCL pin (usually pin 5)
    • SDA to Arduino's SDA pin (usually pin 4)
  3. Connect the breadboard and jumper wires as needed to connect the components.

Software Setup

  1. Install the Arduino IDE on your computer if you haven't already.
  2. Open the Arduino IDE and create a new project.
  3. Copy and paste the following code into the IDE:
    
#include <SoftwareSerial.h>

SoftwareSerial mySerial(10, 11); // Bluetooth module pins

const char* message = "Happy New Year!"; const int messageLength = strlen(message);

void setup() { Serial.begin(9600); mySerial.begin(9600); delay(1000); // wait for Bluetooth module to initialize }

void loop() { for (int i = 0; i < messageLength; i++) { mySerial.write(message[i]); delay(100); // adjust delay to control scrolling speed } delay(1000); // pause for a second before repeating }


4. Upload the code to your Arduino board.

**Bluetooth Configuration**

1. Open the Bluetooth module's configuration settings (usually by pressing and holding the module's reset button while powering it on).
2. Set the module's baud rate to 9600.
3. Set the module's mode to "AT" mode.

**Testing**

1. Connect your Arduino board to your computer using a USB cable.
2. Open the Arduino IDE's serial monitor (Tools > Serial Monitor).
3. Set the baud rate to 9600.
4. Send the message "AT" to the Bluetooth module using the serial monitor.
5. The Bluetooth module should respond with "OK".
6. Send the message "AT+NAME=Your_Arduino_Name" to set the Bluetooth module's name (replace "Your_Arduino_Name" with your desired name).
7. Send the message "AT+PIN=Your_Pin" to set the Bluetooth module's PIN (replace "Your_Pin" with your desired PIN).

**Final Steps**

1. Connect your Arduino board to a power source (e.g., USB cable or batteries).
2. The Bluetooth module should connect to your phone or computer.
3. Open a Bluetooth terminal app (e.g., Bluetooth Terminal on Android or Bluetooth Terminal on iOS) and connect to your Arduino board.
4. Send the message "AT" to the Bluetooth module to start the scrolling text display.
5. The LCD display should start scrolling the message "Happy New Year!".

That's it! You should now have a working Bluetooth scrolling text display that says "Happy New Year!"
