16x2 LCD Interfacing with Arduino



In this tutorial, we will learn, how to interface an LCD (liquid crystal display) with ARDUINO. An LCD screen is an electronic display module having a flat panel display or we can say it’s an electronically modulated optical device that uses the light modulating properties of liquid crystals.

We will interface a 16x2(16 columns and 2 rows) LCD. Other variations are also available like 8x1,10x2 etc.

It is having a wide range of applications; they are also preferred over the 7-segment display as they are cheap, easily programmable and also have the leverage to display special characters.

Now let us interface


Components Required
  • 16x2 LCD                   1No.
  • Resistor 560ohms        1No.
  • Potentiometer 10k      1No.
  • Arduino UNO               1No.
  • Few connecting wires
  • Breadboard



Follow the image below for circuit connection reference.



After making the circuit dump the code given below.

#include<LiquidCrystal.h>

LiquidCrystal lcd(12, 11, 5, 4, 3, 2); 

void setup()

{

 lcd.begin(16, 2);

}

void loop()

{

  lcd.setCursor(0,0);    

  lcd.print("WELCOME TO");

  lcd.setCursor(2,1);          

  lcd.print("SUDOLEARN TECH");

}

The potentiometer can be used to control the contrast of your display.

You can use an LCD to display the output of your projects instead of showing them in the serial monitor, providing a display to the system will make your system independent and interactive.

You can also generate patterns of numbers as shown below

  •   Data is transferred in 4 bits to the pins D4-D7.
  • LCD has its own controller named Hitachi HD44780 LCD controller.

LED Brightness Control using Touch Sensor and ARM

Hey Folks, In this tutorial, we will learn, how to change  the intensity of light using touch sensor the ARM (FRDM-KL25Z). INTRODUCTION The FRDM-KL25Z is an ultra-low-cost development platform for Kinetis L Series KL1x (KL14/15) and KL2x (KL24/25) MCUs built on ARM® Cortex™-M0+ processor.  The FRDM-KL25Z has been designed by NXP in collaboration with mbed for prototyping all sorts of devices, especially those requiring the size and price point offered by Cortex-M0+ and the power of USB Host and Device. The FRDM-KL25Z is supported by a range of NXP and third-party development software. It is packaged as a development board with connectors to break out to stripboard and breadboard and includes a built-in USB FLASH programmer.               FEATURES NXP KL25Z Kinetis KL2x MCU (MKL25Z128VLK4) High-performance ARM® Cortex™-M0+ Core 48MHz, 16KB RAM, 128KB FLASH USB (Host/Device) SPI (2) I2C (2) UART (3) PWM (TPM) ADC (16 bit) DAC (1x 12bit) Touch Sensor
