arduino lcd touch screen shield arduino mega 1012 quotation

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (7" diagonal) bright (14 white-LED backlight) and colorfu 800x480 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel with controller XPT2046 attached by default.

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.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!

For 7 inch screen,the high current is needed.But the current of arduino uno or arduino mega board is low, an external 5V power supply is needed. Refer to the image shows the external power supply position on shield ER-AS-SSD1963.

If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.

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.

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.

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:

How to defeat Joey Ultraviolet in Borderlands 3 Before your battle with Joey Ultraviolet begins in Borderlands 3, there are two important things to note. The first is that throughout the battle lasers will block-off areas of the arena and pools of corrosive lava will be revealed on the floor. You need to keep track of where these traps are so that you can avoid both taking damage and being trapped in part of the map. Secondly, like any boss battle in Borderlands 3, you"ll be attacked by a variety of enemies aside from Joey Ultraviolet. During this boss fight, this includes enemies like Meat Slicer, who have double health bars. First stage Your battle against Joey Ultraviolet begins with you destroying four Crypto Wolves, while Joey watches from on high. Second stage Once you"ve dispatched these wolves, one of the cartel bosses will join the battle. This could be anyone from Franco Firewall to FISH SLAP!!! Whoever you receive will have at one health bar and two shield bars. After you deplete the first shield bar for this boss, they will join Joey on his ledge and a second cartel boss, such as Tyrone Smallums, will attack you. Defeat the two

cartel bosses. Like with the first cartel boss, you need to deplete their first shield bar, which will cause them to join Joey and friend on that ledge they"re so fond of. Third stage The third stage of this boss fight begins when Joey (finally!) and the two cartel bosses return to the battlefield. During this stage, it"s a good idea to keep a distance between you and Joey. This will not only prevent you from taking any unnecessary damage, but you won"t accidentally waste any bullets shooting at Joey. Joey is using the two cartel bosses to power his shield, so you need to kill both bosses first. This involves dealing with any special attacks these cartel bosses might have. Tyrone Smallums, for example, has the ability to change size, regenerating his health when he does so, and creating clones to attack you with. Once you"ve defeated these two cartel bosses, you"ll finally be able to attack Joey directly. Fourth stage Joey will mostly attack you by shooting at you with a gun that deals radiation damage. He can also create waves of shock energy either by jumping and slamming into the ground or by generating them around his body. Joey will also change in size throughout the battle, making him, at times, a harder target to hit. When Joey does begin to grow in size, this means that he"s about to send out a wave of shock energy. Joey attacks you using shock engery. Try to keep your distance between you and Joey throughout the battle, as this will help you avoid his shock energy attacks and prevent him from
