3.2 tft lcd touchscreen display price

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.

3.2-inch TFT Color LCD Module is a TFT LCD Screen Module, 40pins interface, not just a LCD break but include the Touch, SD card and Flash design. So it’s a powerful extension module for your project.

The LCD is 32044PA. It’s a 262K color, 400*240 (resolution), 3.2 inch Widescreen (16:9) TFT LCD screen.The LCD has a wide viewing angle, the contrast is also very suitable.

TFT 3.2" 400*240 With SD Touch Module is designed with a touch controller in it . The touch IC is XPT2046/HR2046, and touch interface is included in the 40 pins breakout.

TFT 3.2" 400*240 With SD Touch Module layout a 40 pins interface for your project, the interface include TFT pins、SD card pins、Touch screen pins and the Flash pins.

The pins named with “D/T_” are the Touch IC output pins; the pins named with “SD_” are SD pins; the pins named with “F_” are the SST25VF016B Flash IC pins; others are TFT pins.

It is compatible with 3.3/5V operation voltage level. TFT power is 2.8~3.3V and the module with PCB have 3V Regulated IC, so it can input 5V, but the data pins can not be more than 3.3V.

Designed for use with the Raspberry Pi Model B/B+, the Seeed 3.2 inch TFT LCD Touch Screen is an easy way to process photos and videos. Easily navigate the touchscreen interface to take photos with up to 17 camera modes, and play videos with a variety of format—MP4 included Read More
