In this part, we’ll highlight some of the projects conceived using STONE Tech’s HMI-ready TFT LCD display modules:

1. Medical Beauty Applications

Several products in the medical and beauty fields have been created using STONE products. Here are three of them:

a. Oxygen Tank Monitor

STONE developed an oxygen monitor for an Italian customer. The monitor uses Stone’s 7-inch TFT LCD screen and was connected to an oxygen tank for medical use.

The finished product displays information about the connected oxygen tank such as concentration levels and other advanced data. All these data are displayed on a streamlined interface developed using TOOLBox software.

b. Fan Control Using an STM32 Board

Another project used an STM32 board to control an electrically-driven fan. It also utilized a STONE module STVC101WT-01.

Communication between the module and the device was established via an MCU connected to a serial port. The device also used the UART interface and TTL.

The end-product featured a touch screen display where fan functions such as speed, dose, and RF are controlled. Moreover, the resulting fan control board can operate at temperatures ranging from -20°C to 70°C, making it a simple yet heavy-duty device.

c. Heart Rate Display and Blood Oxygen Monitor with Arduino

This particular medical device project makes use of four hardware parts, namely:

STONE TFT LCD screen module, STVI070WT-01 model
Arduino Mini Pro development board
MAX30100 Heart Rate and Blood Oxygen Sensor
MAX3232

STONE’s display screen was connected to the Arduino development board through UART. But this required a level conversion achieved by the MAX3232. Meanwhile, the same Arduino board was wired to the MAX30100 module through an IIC interface.

After the wiring process, the device’s TFT LCD user interface was created. This was done through Stone’s TOOLBox software.

Some modifications to the MAX30100 module were made, specifically to the IIC pull-up resistor. The remainder of the project was finished using Arduino codes to finally create a responsive display for heart rate and blood oxygen monitoring.

2. Civil Electricity

Here are five projects in the field of consumer electronics and home improvement:

A. Fingerprint Door Lock

This project aims to create a fingerprint door lock that can enter, scan, compare, and delete fingerprints. It utilized an STM32 development board, fingerprint identification module, and Stone’s STVC050WT-01 LCD display.

STONE LCD screen’s role here is to display the fingerprint module’s status. As with all other projects, STONE TOOLBox software was used to generate the user interface flashed on the screen. Meanwhile, Stone’s LCD screen was connected to the development board and fingerprint identification module with MCU through UART-TTL signals.

B. Connecting A Camera Module To A Display Module

The idea for this project is a real-time display of pictures collected by the camera on the LCD display screen. The TFT LCD STONE module used for this project is a 7-inch serial display module with 800×480 resolution. A camera module, development board, and some wires are needed to complete the project.

The user interface was designed using STONE TOOLBox and Adobe Photoshop. Then, the hardware parts were wired together; some parts needed welding. After that, a simple program was written following MCU to the command control TFT-LCD module.

Coffee Machine Display Screen

This particular project used a STONE serial LCD touch display screen. This functions as the main display for the coffee machine. With the screen installed, you can:

See the current date and time
Check the remaining amount of milk, sugar, and coffee beans
Display the current coffee machine state
Choose the type of coffee to be made (Latte, Espresso, Americano, or Cappuccino)

STONE TOOLBox was utilized again to create the touch user interface. Meanwhile, an MCU code was written to connect the screen to the coffee machine.

D. RGB Lamp Control

RGB lamps that can be controlled through a touch display – this is the aim of this project idea. STONE’s 7-inch TFT LCD display module in STVC070WT-01 was used to connect and control an RGB lamp.

The result of this project demo was that the touch display:

Controlled the lamp’s brightness
Changed the light colors
Shuffled between the four lamp modes

Technologies used to connect the screen module and lamp were MCU and UART.

E. Appliance Controller With Arduino

Last but not least is a basic appliance controller made using STONE’s 7-inch TFT LCD touch screen and an STM32 development board. The touch screen controls lights for various parts of the house. The finished product also collects data about humidity, temperature (indoor and outdoor), and air quality.

3. Precision Instruments

This project resulted in a simple electronic scale made by connecting STONE’s 5-inch touch screen to a development board, an ADC conversion module, and a pressure acquisition module. The finished product can:

Display item weights placed on the tray through the STONE display screen
Perform zeroing, peeling, and changing units

STONE TOOLBox and graphics software such as Adobe Photoshop was used to design the user interface. Meanwhile, the hardware pieces were wired together and an MCU code was written for the electronic scale to be functional.

4. Arduino Automation

STONE’s TFT LCD intelligent touch modules can be paired with Arduino technology to automate a variety of processes. This project clearly demonstrates this.

Here, a sensor directly connected to Arduino Uno is monitored by the display screen in real-time. Moreover, two light bulbs connected to Arduino are directly controlled by the display screen as well.

This project utilized a 10.1-inch HMI Display under Stone’s Civil Type Series.

5. Public Transfer

We mentioned the car dashboard example earlier in this article, and now it’s an actual project idea created by STONETech.

This project is all about making a car display dashboard using a 10.1-inch STONE LCD touch screen. The on-board display interface for a used car contains the following:
