use the function to scroll the text from right to leftĮxplanation of code: In the above code, we simply print “Welcome to LinuxHint” on LCD and call the function of the “scrollDisplayLeft()” in Arduino code for scrolling the text from right to left position. declared the Arduino pins with LCD pins (RS, E, D4, D5, D6, D7 ) In the above circuit diagram, we have connected the LCD pins with Arduino pins in the following way: Simulation and Hardwareįor the simulation of the above circuit, we need components: Then with the help of the rightToLeft() function, we print the text “LinuxHint” on LCD with a delay of 500 milliseconds and then display it from left to right by using the leftToRight() function.īefore using these functions, set the cursor from where you wanted to start the printing of output on the LCD using the setCursor() function. Reverse the string to print Right to LeftĮxplanation of code: In the above code, we have initialized the LCD with Arduino by including its library, “LiquidCrystal” and declaring its connections with Arduino pins. for loop to display string character by character These functions are used in the Arduino code: Syntax: lcd.rightToLeft() Example of using leftToRight() and rightToLeft() functions in Arduino This function is used to print the output on LCD from right to left direction but a question arises in the mind that by default the output is printed on LCD from right to left direction, then what is a need of this function? The answer to this question is if the leftToRight() function is already called in the code and the output is displayed from left to right then to change its direction, we use the rightToLeft() function.
Once this function is invoked, the cursor will start printing the text from the left direction to the right of the LCD. This function is responsible for printing the text on the LCD from the left to right position. The functions used for controlling the direction of text on LCD are:Īll these functions are explained with a simple example.
The direction of the text on LCD can be controlled by using different functions of the Liquid Crystal library, these functions decide whether the text should print on LCD from right to left or left to right.

How to control the direction of text on LCD using Arduino In this write-up, all the functions which can control the directions of the text are discussed. The LCDs are an important electronic component that is widely used in Arduino projects to display the output. These built-in functions control the directions of text, the time up-to which text should be displayed on the LCD, and the positions of the cursor on the LCD. The text can be displayed on the LCD which is interfaced with Arduino using the built-in functions of Arduino.
