tft lcd 3.5-inch touch screen with uno r3 made in china

Note: There is a film on the LCD, if there is scratch on the film when you receive the item, pls try to remove the film with your finger nail from the corner of the LCD, thanks.

To make my projects with Arduino even more interesting bought this display of 3.5 inches. I thought I had bought a version with touch screen, but then I discovered that the version with support for touch screen sells in this other link.

It is a shield, IE, is to be plugged directly into the Arduino. My complaint is that does not extend any PIN and practically uses all, IE, You can"t do much on the Arduino UNO but play with the display. Detail to support the SD card to upload images.

Look at the game with different fonts and colors. To make something appear you must install some. I installed from this link, the version 1.1. The libraries are the Adafruit_GFX and Adafruit_TFTLCD. The touchscreen version also needs a library that can be downloaded on the same link, switching to the version 2.0.

Take a look at the video I made showing a program that generates circles, rectangles and triangles with random colors, In addition to the display pattern that comes with the library. I used the Arduino UNO:

I found the display quite slow. Not to make a watch, for example, because the display is blinking a lot when updated second by second. Maybe we can make a graph of the analog input A5, that doesn"t appear to be used to control, but to do so would have to weld or fit any wires directly into the board, because this shield does not extend any of the pins. Who knows in the Arduino Mega works best? I leave below link to the version with touchscreen and without touchscreen:

This TFT LCD Screen Module , not just a LCD break but include the Touch , SD card and Flash design. So it"s a powerful extension module for your project.

Kuongshun Electronic, one of the international well-known manufacturers and suppliers of 3.5 inch tft touch screen module for mega 2560 r3 which is situated in China, now has quality products for sale. We are equipped with a group of professional and experienced workers, as well as advanced equipment. You can rest assured to buy discount and low price 3.5 inch tft touch screen module for mega 2560 r3 made in China from us and check the pricelist with us.

This module is a 3.5-inch TFT LCD module with “320X480” resolution and 65K color display. It is suitable for Arduino Uno and Mega2560 development boards, and also supports SD card expansion function. It uses 8-bit parallel port communication, and the driver IC is ILI9486.

The 3.5-inch display is a ready-made shield for Arduino Uno, which can also be placed on the Arduino Mega. The pins of this shield are designed to be easily installed on the Arduino. The bad point about these modules is that they use all Arduino Uno pins.

my_lcd.Fill_Round_Rectangle(my_lcd.Get_Display_Width()/2-1-120+1, my_lcd.Get_Display_Height()/2-1-60+1, my_lcd.Get_Display_Width()/2-1+120-1, my_lcd.Get_Display_Height()/2-1+60-1,5);

I changed the Adafruit libraries for TFT: GFX , TFTLCD and TouchScreen. I join all in this one library, the library SPFD5408, to avoid problems with duplicate libraries and enables also have the original library Adafruit ready for use in other projects with another TFT hardware.

Description:; This is a 2.8 inch TFT LCD expansion board. This display has a controller built into it with RAM buffer so that almost all work is done by the TFT.; It leads out the pins of the TFT and pins pitch is 2.54 mm, so the secondary development is easy. With the GPRS module, you can design your phone. With the NFC reader module, you can create access control systems with the photos show. With voltage and current sensors, you can make an oscilloscope.;

- Compatibility: Because the logic level is 3.3V, it is compatible with 3.3V Arduino board, you generally need to add a level conversion circuit if you use a 5V Arduino Board (Arduino UNO R3 / Arduino Mega2560 / Arduino Leonardo).
