People May Ask
How can I fix my LCD screen is a common query that most people have. The LCD cannot be fixed, is the response. If the LCD becomes damaged, you must get a new one. Changing the glass alone is not as complicated as replacing the LCD.
Physically measuring the screen allows one to establish the size of a desktop computer monitor. Start at the top-left corner and drag a measuring tape diagonally to the bottom-right corner. Make sure to simply measure the screen and leave off the bezel, the screen's plastic border.
A 21-inch monitor, for instance, provides nearly exactly 100 pixels per inch (PPI) while displaying a 1920 x 1080 full HD image. Although 21" is simply too little for most modern games, that would be the optimal aspect ratio.
A 22-inch monitor is tiny enough to fit on a desk, but it also works well with two screens in a twin monitor configuration. By doing this, you can quadruple the screen area without the monitors taking up a lot of desk space.
You might be shocked to learn that LED screens consume less electricity while producing more brightness than their competitors. Because LED panels are brighter and more visible even at the height of the day, they are chosen for outdoor displays.
The LCD screen must be brighter than the amount of light reflected from the display surface in order for it to be readable in outdoor settings with intense ambient light. The LCD's brightness must, at the very least, be 2.5 times more than its reflected light for human eyes to perceive it comfortably.
You'll feel more at ease when reading in the 2,500–3,000 K warm light, and you'll feel better afterward. The best light source for comfortable work is natural light, which ranges in color temperature from 4,900 to 6,500 K. 6,500 K cold light provides outstanding brightness and enhances overall attentiveness.
The 20-20-20 Rule for preventing and treating digital eye strain is well known to optometrists. Every 20 minutes, the term advises taking a 20-second break to look 20 feet away.
The eye can be trained by staring at a screen for extended periods of time. The 20-20-20 rule can be used to assist avert this issue. A person should spend 20 seconds looking at something 20 feet away for every 20 minutes they spend looking at a screen. Following the guideline is a wonderful method to keep track of how often you should take breaks.

MEGA after connecting to an Arduino UNO. I powered on the device and saw a blue screen with no characters after connecting the SDA to A4 and SCL to A5, then +5 and Gnd. There seems to be an issue. The characters became visible after the LCD Contrast Variable Resistor on the bottom was adjusted. I tweaked both of my boards so that the display was washed out. Use the Sketch Menu to load the library, then select Include Library and Add the "LiquidCrystal_I2C_LIB.zip" zip file. Use File, Examples, LiquidCrystalI2C to test a little code sample. Seems quite practical. T. Dr.
nice shade of blue. I used two I2C wires—two for electricity and two for I2C—to connect two devices to an Arduino Mega concurrently. By slicing and/or soldering the circuit pads on the I2C adapter daughter-board, you can use more than one by changing the I2C address that is set by default. Although I had some trouble regulating the backlighting, I didn't find it to be a big deal. Using the libraries LiquidCrystal_I2C.h and Wire.h, Arduino programming is simple. I
However, they only offer you a Fritz "picture" of the circuit board; they don't provide you the pin out. 2) Their sample code is very complicated if you are using this as one of your first LCD tools, as I am. I constructed the pin out table in the attached image. Try the following commands: lcd.print("Hello World!"); lcd.scrollDisplayLeft(); delay(250); lcd.scrollDisplayLeft(); delay(250); lcd.scrollDisplayLeft(); // etc. Actually, if you want to complicate the example, place the aforementioned code in a loop.
