9/17/2023 0 Comments Arduino print to screenThis enables us to use short functions to control the screen instead of having to manually code each letter or cursor movement. We begin by importing the Liquid Crystal library. Lcd.setCursor(0,1) // set cursor to column 0, row 1 Lcd.print("Hello World") // Display this text Lcd.setCursor(0,0) // Set the cursor to first character, first row Lcd.begin(16,2) // Defines the number of characters and rows For the first example, we will only be using the setup loop as we just need the screen to display “Hello World” and “The DIY Life” on the screen without any further changes. Upload the Code to Control the LCD Screen Displaying Static Text ![]() Be careful when connecting the pins as the numerical sequence on the Arduino pins is the opposite to the screen pins. Pins 2,3,4 and 5 are the data transfer pins and are connected to d7, d6, d5 and d4 respectively. The pin connections to the LCD screen are as follows: Pin 10, 11 and 12 are used to control the registers and are connected to the E, RW and RS pins respectively. The 220Ω resistor is connected along the positive supply for the back light in order to limit the current. The 10K pot is used to adjust the contrast of the screen. You can solder a wire ribbon onto the screen and then pins on to the ends of the wires which then plug directly into the Arduino or you can solder a pin header onto the screen and plug it into a breadboard which you can then connect to the Arduino using jumpers.
