branchement tft lcd color monitor quotation
Whether you"re commuting, running errands, traveling on vacation, or just backing out of your driveway, knowing exactly what"s behind you is important for safety. A rear-view or back-up camera and monitor can help to protect your car, your person, your passengers, and pedestrians. Here are some tips for choosing TFT (thin-film transistor) LCD video monitors and cameras to provide a field of vision that can enhance your peace of mind behind the wheel.
Some kits come with just a waterproof rear-view camera with night vision, without any type of monitor. These can be plugged into a DVD player, a monitor you purchase separately, or an existing display unit in your car. Other kits will come with both a rear-view camera and a TFT LCD monitor of some kind, while other kits will only offer a monitor without the backup camera. Some kits come with multiple cameras for larger vehicles and can even include a multiview display so you can see what the entire camera system is seeing at once. Which kit you choose will depend on your individual needs and the size of your vehicle.
In many cases, you can install a rear view camera and 7-inch LCD monitor yourself. This depends on whether you already have a monitor of some kind installed in your car, or if you choose a monitor that simply mounts on the dash or a wireless monitor. If the monitor needs to be installed in the dash and wired into the electrical system; however, you may need professional installation. Many backup cameras simply screw onto your license plate with existing screws and take little time to install. Some cameras are also wireless and will beam the image straight to a Bluetooth wireless monitor.
There are several different types of monitors you can pair with your back-up camera. Some monitors will simply mount on your dash and can be plugged into a 12V socket in your car. Other monitors actually take the place of your rear-view mirror, turning it into a full-time monitor. Other monitors need to actually be mounted into your dash and can take the place of an existing radio, audio unit, or touch-screen device. Kits are made to fit RV trucks and buses as well as cars.
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.
Next is the distance sensor button. First we need to set the color and then using the fillRoundRect() function we will draw the rounded rectangle. Then we will set the color back to white and using the drawRoundRect() function we will draw another rounded rectangle on top of the previous one, but this one will be without a fill so the overall appearance of the button looks like it has a frame. On top of the button we will print the text using the big font and the same background color as the fill of the button. The same procedure goes for the two other buttons.
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.
