diy hd 5 tft lcd display pricelist

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.

In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

In which “Hello, World!” is the text you want to display and the (x, y) coordinate is the location where you want to start display text on the screen.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

Note: some people find issues with this display when trying to read from the SD card. We don’t know why that happens. In fact, we tested a couple of times and it worked well, and then, when we were about to record to show you the final result, the display didn’t recognized the SD card anymore – we’re not sure if it’s a problem with the SD card holder that doesn’t establish a proper connection with the SD card. However, we are sure these instructions work, because we’ve tested them.

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.

Even if you are extremely careful with your hardware, it can be unavoidable at times to run into issues such as a cracked or broken computer screen. Just because you’re experiencing problems with your display doesn’t mean that your laptop is beyond saving, however.

If you’re wondering about broken laptop screen repair costs, you’ll be happy to know it’s not as expensive as you may assume. Professional repair costs are usually around $300 or so [1]. If you are comfortable working on your laptop yourself, you can usually find replacement screens online for reasonable prices - sometimes as low as $50 to $100 - and it often only takes an hour or two to complete the replacement job.

If you’re willing to take the leap and do this yourself, then you can end up rescuing a computer you may have thought you needed to replace. Here are 5 steps you can take to successfully replace or repair your cracked computer screen.

The first step is making sure the device powers up successfully and that the screen is the only issue you need to address. As a test, hook your laptop up to a separate monitor. If your laptop seems to function well, then it’s likely that the broken laptop screen is all you have to worry about. Keep in mind that some laptops need to have some function keys pressed in order for an external display to work properly.

Note: If you’re concerned about your laptop’s touch screen repair, it can be more complicated to fix this problem without professional help. These displays are designed with factors like sensitivity in mind, so it’s a good idea to have an expert take a look at it, even if it means spending a bit more than anticipated.

Fortunately, finding the right screen for your device doesn’t have to be stressful. Often you can find what you are looking for simply by entering your laptop model number into the search bar of online retailers. You may also want to include the search term “LCD” in order to narrow down the accessories that are available for your computer. For the most part, screens should be priced fairly reasonably and you may even be able to buy some for around $50, although it depends on the type of computer you have.

Some sellers may use another form of identification for the model of your laptop, so double check that you chose the right option before you purchase. Almost all the information you need should be displayed on the seller’s listing. Again, take the time to compare your device’s specs with the screen you’re purchasing, and also make sure that the video cable on the back of your screen matches what the vendor shows online. Most of the time, it’s fairly easy to know if the right screen is available.

Once you have done that, you should identify the stickers that cover screws on the screen bezel. You can usually find them near the bottom of your screen where the hinges would be when you have your display opened. There should be two.

One of the trickier parts of replacing your laptop screen will be removing the LCD. First, make sure that the bezel is completely off so you can have unfettered access to the LCD screen. It will be secured onto the laptop’s metal frame, and you will have to take it off from the left and right sides.

There will be two more screws to loosen at the top corners before you can lift the screen slightly away from the metal frame. You’ll probably find a few more screws securing the LCD on the sides, and these will also need to be unscrewed. In some cases, heavy duty tape may have been used instead.

After you remove the attachments, your screen should now lie on your keyboard. It can be a bit of a challenge to make sure there is enough space between the LCD and the metal frame, but you should be gentle to avoid ruining the video cable that runs from the back of the screen to the body of the laptop. If this is damaged, you will need a professional’s help to repair it.

Now it’s time to disconnect the cable from the LCD. You can usually find the connectors in the center, though they may alternatively be located at the bottom of your screen. It’s likely that adhesive was used to connect the two, so you will need to gently pry one from the other. There may also be some tape that needs to be removed, but overall it should be pretty simple to disconnect your LCD from the video connector. Set it somewhere away from your tools.

As you remove the screen, you should be able to locate where your new one will go. Place it face down within the frame so it fits perfectly. After that, you can reattach the video connector so it is placed exactly where the previous LCD sat. Make sure that it is as aligned as possible then attach it with tape or adhesive.

From there, you should be ready to restart your computer. Put the battery in and connect your laptop to a power source before turning it back on. If there is no display, then you will need to double check that everything was properly put back together.

Repairing a broken laptop screen doesn’t have to be done by a professional. If you have the time and interest, then you can end up saving a lot of money by doing it yourself. By following these DIY steps, you can have your laptop display back up and running in an hour or two.
