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.

TTGO has been committed to the design, development, and sales of development boards, suffering from the embarrassment of having no enclosure for the products. Many customers ask why they don"t add an enclosure to the product, so we began to think about how to add a suitable enclosure to our development board, which is beautiful and playable. We were inspired when we chose the packaging carton for the product. The TTGO-carton is based on the combination of the development board and the carton, allowing users to create exclusive music albums and smart speakers through ESP32 dual-core bluetooth and WIFI function. While playing music on bluetooth, we can grab picture album display from the website via WIFI. And we can also make smart audio by connecting microphone, DIY your own creativity
