In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work  you can check my particular tutorial. Here you can download that file:

So here I decided to make a small project related to the ventilator. It is very convenient to develop with the STONE TFT LCD serial port screen. I use it as the display interface. In addition, I need an external main controller to upload data. Here I chose esp32, which is also a popular chip, and the development is relatively simple.

In this tutorial, you will build a serial port screen project. The screen can interact with MCU, control and generate waveform through esp32, and display it on the screen. This project will be very helpful to collect the patient’s respiratory rate waveform.

Here we will do a ventilator project. After the ventilator is powered on and turned on, there will be a start-up interface, and the word “open ventilator” will be displayed. Clicking on it will have a click effect, accompanied by a voice prompt, indicating that it has been turned on successfully. Finally, it will jump to a function selection interface. In this interface, we can choose the ventilator mode: CMV PCV SIMV PS CPAP PEEP, If the setting is wrong, you can click Reset, and then click OK to return. Next, click the “vendor waveforms” button, there will be the same button effect, and then enter the heart rate waveform display interface. At this time, the STONE TFT LCD screen will send the serial command, triggering the esp32 MCU to start uploading the waveform data.

Because STONE TFT LCD has an audio driver and reserved corresponding interface, it can use the most common magnet speaker, commonly known as a loudspeaker. The loudspeaker is a kind of transducer which transforms the electrical signal into an acoustic signal. The performance of loudspeaker has a great influence on the sound quality. Loudspeakers are the weakest component in audio equipment, and for audio effect, they are the most important component. There are many kinds of loudspeakers, and the prices vary greatly. Audio electric energy through electromagnetic, piezoelectric, or electrostatic effects, so that it’s a paper basin or diaphragm vibration and resonance with the surrounding air (resonance) and produce sound.

Esp32is a single-chip scheme integrated with 2.4 GHz Wi-Fi and Bluetooth dual-mode. It adopts TSMC’s ultra-low power consumption 40 nm technology, with ultra-high RF performance, stability, versatility, and reliability, as well as ultra-low power consumption, which meets different power consumption requirements and is suitable for various applications scenarios. At present, the product models of esp32 series include esp32-d0wd-v3, esp32-d0wdq6-v3, esp32-d0wd, esp32-d0wdq6, esp32-d2wd, esp32-s0wd and esp32-u4wdh. Esp32-d0wd-v3, esp32-d0wdq6-v3 and esp32-u4wdh are chip models based on Eco v3.

First of all, the development of the software part requires the installation of IDE. Esp32 supports the development and compilation in the Arduino environment, so we need to install the Arduino development tool first.

After downloading, double-click to install it. It should be noted that Arduino ide depends on the Java development environment and requires a PC to install Java JDK and configure variables. If double-click startup fails, the PC may not have JDK support.

Module with WiFi Espressif ESP32-S2. It has 4 MB of Flash memory, 2 MB of external PSRAM memory, integrated WiFi 802.11 b/g/n transceiver and a JST-PH 2.0 connector for connecting a LiPo battery. The board has a TFT LCD display and an RGB LED. FeatherS2 is easy to integrate with sensors due to the available STEMMA QT connector (Qwiic compatible).

The module offers great possibilities in the field of IoT systems and can be used both to control LEDs and to transfer data to a specific platform. FeatherS2 can also be programmed using the Arduino IDE, ESP-IDF or CircuitPython. Full documentation is available on the product page.
