Introduction: Write Any Thing on LCD With One Button With Arduino Its a Game

By
About: I love electronics .Arduino automation

In this project i use only one on button to write any thing on LCD

to write letter A press one time
to write letter B press two times

to write letter C press three times

and so on up to Z

to give space press 27 times

for back sapce press 28 times

its a game

Step 1: Parts Required for Making

1 arduino

1 LCD

Jumper wires

1 push button

bread board

Step 2: Assembly of Parts

in this project you can assemble parts lie this

in the picture there are two main things

one lcd

one push button

Step 3: Game for One Line

in this code you can write program only for second row 

int r = 0;
int le = 0 ;
int timer = 1000;
#include<LiquidCrystal.h> 
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
int sw1 = 6;
void setup() {
  
  lcd.begin(16, 2);
  
  lcd.print("Write Name");
  pinMode(sw1, INPUT);
  digitalWrite(sw1, HIGH);
 lcd.setCursor(0, 1);
  lcd.print("0");
  
}
void loop() {
 
  
 
  if(digitalRead(sw1) == LOW) {
  le = le + 1;
  delay(timer);
  
  
 
 if(le == 1) {
  delay(1000);
  lcd.setCursor(r, 1);
  lcd.print("A");  
  
 }
 if(le == 2) {
  
  delay(timer);
  lcd.setCursor(r, 1);
  lcd.print("B");
    
 }
 if(le == 3) {
delay(timer);
  lcd.setCursor(r, 1);
  lcd.print("C");
   }
   if(le == 4) {
  delay(timer);
  lcd.setCursor(r, 1);
  lcd.print("D");  
 }
 if(le == 5) {
  delay(timer);
  lcd.setCursor(r, 1);
  lcd.print("E");  
 }
 if(le == 6) {
  delay(timer);
  lcd.setCursor(r, 1);
  lcd.print("F");  
 }
 if(le == 7) {
  delay(timer);
  lcd.setCursor(r, 1);
  lcd.print("G");
   }
   if(le == 8) {
  delay(timer);
  lcd.setCursor(r, 1);
  lcd.print("H");  
 }
 if(le == 9) {
  delay(timer);
  lcd.setCursor(r, 1);
  lcd.print("I");  
 }
 if(le == 10) {
  delay(timer);
  lcd.setCursor(r, 1);
  lcd.print("J");  
 }
 if(le == 11) {
  delay(timer);
  lcd.setCursor(r, 1);
  lcd.print("K");
   }
   if(le == 12) {

  lcd.setCursor(r, 1);
  lcd.print("O");
   }
   if(le == 16) {
  delay(timer);
  lcd.setCursor(r, 1);
  lcd.print("P");  
 }
 if(le == 17) {
  delay(timer);

Step 4: How to Operate One Line Lcd Disaplay

to write letter A press one time

to write letter B press one time

to write letter C press one time

and so on up to Z

to give space press 27 times

for back sapce press 28 times

its a game

Step 5: Now Game for Full Screen

now you can operate full screen by using one button

int r = 0;
int le = 0 ;
int timer = 200;
int c =0;
#include <LiquidCrystal.h>

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

  digitalWrite(sw1, HIGH);
lcd.setCursor(c, r);
  lcd.noCursor();
  delay(timer);
  lcd.cursor();
  delay(timer);
  
}

Step 6: How to Operate Full Screen

Letter format is same

its start from first row and column

when you have to go to second row

first fill first row and then second can be fill

Step 7: To Save Lcd Written Data I Use Eeprom

now to save data that is written on lcd i use eeprom

this function is very use full

Step 8: What You Can Do

you can also add numbers

special charactor

and option of capital letters and small small letters

give us feed back and show me that you make
