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.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

The third example is a game. Actually it’s a replica of the popular Flappy Bird game for smartphones. We can play the game using the push button or even using the touch screen itself.

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.

Next we need to define the fonts that are coming with the libraries and also define some variables needed for the program. In the setup section we need to initiate the screen and the touch, define the pin modes for the connected sensor, the led and the button, and initially call the drawHomeSreen() custom function, which will draw the home screen of the program.

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.

Now we need to make the buttons functional so that when we press them they would send us to the appropriate example. In the setup section we set the character ‘0’ to the currentPage variable, which will indicate that we are at the home screen. So if that’s true, and if we press on the screen this if statement would become true and using these lines here we will get the X and Y coordinates where the screen has been pressed. If that’s the area that covers the first button we will call the drawDistanceSensor() custom function which will activate the distance sensor example. Also we will set the character ‘1’ to the variable currentPage which will indicate that we are at the first example. The drawFrame() custom function is used for highlighting the button when it’s pressed. The same procedure goes for the two other buttons.

So the drawDistanceSensor() custom function needs to be called only once when the button is pressed in order to draw all the graphics of this example in similar way as we described for the home screen. However, the getDistance() custom function needs to be called repeatedly in order to print the latest results of the distance measured by the sensor.

Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.

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.

We"ve all been there. Tapping, swiping or zoom-pinching, there"s often a moment when the touchscreen display on your tablet refuses to respond. How do you overcome this, and achieve tablet-tapping Zen?

As the primary mode of interaction between you and your apps, the tablet touchscreen is vitally important. Any damage inflicted – knocks to the device, scratches or worse – will degrade the touchscreen. Short of paying for a replacement, you will need to make sure the display is kept safe and intact.

The following tips – also suitable for smartphones – will help you resolve your tablet"s touchscreen responsiveness issues. We"ve designed this guide for all touchscreen tablet computers. So, if your Android tablet touchscreen is not working, or your device uses iOS, or Windows, the answers you need are right here.

Perhaps the best place to start in troubleshooting screen responsiveness issues is to make more system RAM available. This may take a moment but should give you an idea of how bad the problem is.

If your Microsoft Surface touchscreen is not working, or you use a different Windows 10 tablet, close as many desktop apps as is practical can before switching to the Start screen. Then:

Restarting a tablet isn"t a case of just tapping the power button to turn the screen off. Instead, the whole device must be switched off and back on again.

After all, how do you fix an unresponsive touchscreen when most of your options are accessible through the screen? The answer is surprisingly simple: connect a mouse.

Knowing which area(s) of the touchscreen are failing to respond correctly can be useful in diagnosing what is wrong. This information would prove useful to any engineer who ends up repairing the tablet.

On Android, free calibration and testing apps are available. Touch Screen Test is a good app that helps you find specific areas where input is not detected.

For devices that are in warranty, this means contacting the manufacturer and arranging a return, or dropping into a store. iPads, for example, can be taken to Apple Stores; Samsung tablets can similarly be taken to Samsung stores. In some cases, doorstep repairs are possible, where the device is repaired in a mobile Samsung-approved workshop parked outside your home. If your Samsung tablet touchscreen is not working, this fast-repair option might be available.

Whether you"re using a Samsung, LG, iPad, or your Lenovo tablet touch screen is not working, check your device manufacturer"s support pages to find the correct steps to arrange repair. Make it clear what steps you have attempted to resolve the touchscreen issues.

As noted above, if your tablet screen is cracked, it can impact touch reliability. Whether big or small, a cracked tablet screen will always fail eventually. Having your tablet looked at by an engineer under warranty is the smart option but isn"t always possible. If your tablet is out of warranty and the screen is cracked, you have two options:

Wondering how to repair a tablet touch screen yourself? For cheaper tablet models repair makes more sense than with premium brands. So, if you have a Vankyo, Onn, Yosatoo, Contixo, or Amazon Fire tablet with a screen that is not working or responding to touch, consider replacing the display yourself. Our guide to replacing a cracked Amazon Fire tablet display will help here.

Most problems can be avoided with care, a screen protector, and a case for your tablet. But where possible, avoid water and don"t get your tablet wet.

Insert the TF Card to Raspberry Pi, connect the Raspberry Pi and LCD by HDMI cable; connect USB cable to one of the four USB ports of Raspberry Pi, and connect the other end of the USB cable to the USB port of the LCD; then supply power to Raspberry Pi; after that if the display and touch both are OK, it means drive successfully (please use the full 2A for power supply).

After execution, the driver will be installed. The system will automatically restart, and the display screen will rotate 90 degrees to display and touch normally.

（" XXX-show " can be changed to the corresponding driver, and " 90 " can be changed to 0, 90, 180 and 270, respectively representing rotation angles of 0 degrees, 90 degrees, 180 degrees, 270 degrees）
