The TFT shows only a white and static screen with any example of the librery... I´m already change the parameters line with... "UTFT myGLCD(ILI9341_16, 38,39,40,41);" and "UTFT myGLCD(SSD1289, 38,39,40,41);"

I am using visual code with PlatformIO extension, and the library UTFT modified for ILI9341_16, becuase my supplier told me that this was the correct one.

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.

The next example is controlling an RGB LED using these three RGB sliders. For example if we start to slide the blue slider, the LED will light up in blue and increase the light as we would go to the maximum value. So the sliders can move from 0 to 255 and with their combination we can set any color to the RGB LED,  but just keep in mind that the LED cannot represent the colors that much accurate.

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.

Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (3.5" diagonal) bright (6 white-LED backlight) and colorful (18-bit 262,000 different shades)! 320x480 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel with controller XPT2046 attached by default and a optional capacitive touch panel with controller FT6236 attached by default, so you can detect finger presses anywhere on the screen and doesn"t require pressing down on the screen with a stylus and has nice glossy glass cover.

The pin32 (SDO) of 3.5 display module is also used by touch panel or SD card SPI interface, so we must cut off this pin to avoid conflict with the touch panel or SD card.

The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino (Due/Mega 2560).

This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. You can connect more sensors, buttons and LEDs.

TFT Touch Shield V2.0 is a resistive touch screen, compatible with Arduino/Seeeduino/Arduino Mega/SAMD21 platforms. It can be used as display device or sketch pad. Compared with the previous version, 2.8""TFT Touch Shield V1.0, we upgraded the screen driver to a more professional chip, ILI9341 driver, providing different pin-saving SPI communication without sacrificing the data transmitting speed. Due to the communication method change, programs developed for the original version are needed for modification before being transplanted to the new version. With a SD card module integrated on this shield, this shield reserves capability for other expansions of your project.

We recommend using Seeed_Arduino_LCD with internal flash chips larger than 128k. If you have a smaller flash device, I recommend using the TFT_Touch_Shield_V2.

Step1. Download and Install Seeed_Arduino_LCD. if you don"t know how to install an Arduino library, please refer to the tutorial (HOW TO INSTALL AN ARDUINO LIBRARY).

In addition to all the features of the previous board, the MEGA now uses an ATMega16U2 instead of the ATMega8U2 chip. This allows for faster transfer rates and more memory. No drivers needed for Linux or Mac (inf file for Windows is needed and included in the Arduino IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc.

1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V. The second one is a not connected pin, that is reserved for future purposes.

Say goodbye to messy cables and clueless pluging/unpluging! This  Sensor Shield  is a powerful expansion shield  for Arduino Mega Due. It is large enough to carry up to 3 Xbee slots, 1 microSD slot and shield headers for most Arduino shields on the market. Besides, we also added a prototyping area for convenience and adaptability for customized projects.

The breakouts for Digital pins are 14 to 53, Analog pins 6 to 15 and PWM pins 2 to 9. All pinout is a Gravity interface which allows plug-play of Gravity series sensors.  And standard Arduino UNO pinout is reserved to stack more Arduino Shield. This shield can really be a major communications hub or "Mothership" for your Arduino, robot or IOT projects.

Each Xbee socket is connected to a different pin. Xbee socket 1 is connected to the main Serial port. While Xbee socket 2 to Serial1() and Xbee socket 3 to Serial2() on Arduino IDE.

A external power connector for servos, as in other products of this family. If you need to power a large array of servos, use the screw terminals to connect your power supply and just drive it directly from your Mega.
