Upload this and it will read the resistance of your buttons on the lcd screen

/* /* Arduino 2x16 LCD Detect Buttons resistance */


#include <LiquidCrystal.h>

//LCD pin to Arduino
const int pin_RS = 8;
const int pin_EN = 9;
const int pin_d4 = 4;
const int pin_d5 = 5;
const int pin_d6 = 6;
const int pin_d7 = 7;

const int pin_BL = 10;

LiquidCrystal lcd( pin_RS,  pin_EN,  pin_d4,  pin_d5,  pin_d6,  pin_d7);

void setup() {

lcd.begin(16, 2);

lcd.setCursor(0,0);

lcd.print("  Press Any Key ");
lcd.setCursor(0,1);
lcd.print("Resistance:");
}

void loop() { int x; x = analogRead (0); lcd.setCursor(12,1); lcd.print (analogRead (0)); lcd.print(" "); delay (500); }
