To display customs characters and text.If we want to scroll the text in right we can use lcd.scrollDisplayRight.

The sketch uses the lcd.scrollDisplayLeft function to scroll the display to left when the text is longer than the width of the screen. This sketch has a marquee function that will scroll text up to 32 characters in length. This sketch demonstrates both lcd.ScrollDisplayLeft.

We want to scroll text, for example: to create a marquee that displays more characters that can fit on one line of the LCD display. The function uses lcd.display() and lcd.noDisplay() to turn the display text on and off (without clearing it from the screen’s internal memory). To blink the entire display there is a function named displayBlink to flash the display for a specified number of times. The sketch calls blink and noBlink function to toggle cursor blinking on and off. It also illustrates how to turn the display on and off for example, to draw attention by blinking the entire display. It’s easy to use and programmer-friendly. But why is it commonly used in many applications It’s available in most of the stores. This sketch shows how you can cause the cursor to blink. It is called 16×2 because you can display 16 characters in one column and it has 2 rows so, in total, you can display 32 characters on it. We may also draw attention to a specific area of the display.

Make sure that you follow the instructions for installing that library - specifically you must remove all traces of the I2C libraries that you have previously tried and you must also remove or rename the default LiquidCrystal library.Now we want to blink the cursor and turn the display on or off. I suggest that you modify his example program to just display a simple message in setup() and keep loop() blank as you did in the program that you posted above. Here is a blog that seems to use your I2C adapter with fm's library. Most I2C libraries are written to support a specific I2C adapter since they have to account for the actual layout of the connections on that adapter.Īnother choice is to use a library, such as the one by Francisco Malpartida (fm), that has provisions to deal with many I2C adapters since the layout of the connections can be specified in the 'constructor'. (I also tried about 10 different libraries) I also use this library : GitHub - kiyoshigawa/LiquidCrystal_I2C: LiquidCrystal_I2C Library for Arduino designed to work with the Elefu Control Panel I2C LCD Backpack.
