arduino lcd library how to write blank line

And it comes pre-installed with Arduino IDE.

It is a great library to control LCD with an Arduino. We are using Arduino LiquidCrystal Library to control our LCD.

But in practical you can’t see much difference. Technically 8 bit mode is faster because 8 data pins are used. Note :- If you want to use the 8-bit mode simply connect the remaining four data pins i.e D0 to D3with four Arduino digital pins and change the code accordingly. We are using the 4-bit mode so you don’t need to connect anything to pins D0 to D3. I connect those pins to Arduino digital pin no 4, 5, 6, 7 respectively. Connect the anode pin with the +5ve through a series 220Ω resistor and connect the cathode to the ground.Ĭonnect the RS pin to Arduino pin no 2, R/W pin to ground, and EN pin to Arduino pin no 3. You can control the backlight through those pins. The last two pins from the left are anode and cathode. Connect a 10 kΩ variable potentiometer to it so that you can control the contrast. Vo pin is for controlling the contrast of the LCD. So connect LCDs VCC to the +5ve pin of Arduino and VSS pin to the ground. Then VCC, V0, RS, R/W, EN, D0 to D7, and at the last Anode and Cathode.Ī typical 16×2 LCD needs 5v to operate. The very first pin from the left is the VSS pin. 16×2 LCD Pin out :ġ6×2 LCD has 16 pins and can be operated in 4-bit (using 4 data lines) or 8-bit mode (using 8 data lines). So you can easily modify the code a little bit and it would work for 20×4 LCD. Component need for Arduino LCD Tutorial 16×2 Character LCD x1Ĭharacter LCDs are available in many different sizes (16×2 or 1602, 20×4 or 2004, etc.) but most of them use the same HD44780 parallel interface LCD controller from Hitachi. I will show you how you can print text, blink text, scroll text, display custom characters. In this tutorial, I will show you how to use a 16×2 Character LCD display with Arduino.
