Radio cz.2 - Wyświetlacz , potenciometr , pamięć !

Hej !
 Dziś krótko, stworzyłem ala radio z wyświetlaczem i pamięcią.

 Kod 1 - Wersja finalna działają buttony , wgrane najpopularniejsze stacje , brak jednoczesnej obsługi potenciometru ;C
//Sample using LiquidCrystal library
#include <LiquidCrystal.h>
#include <Wire.h>
#include <TEA5767Radio.h>
TEA5767Radio radio = TEA5767Radio();

LiquidCrystal lcd(8, 9, 4, 5, 6, 7);


// define some values used by the panel and buttons
int lcd_key     = 0;
int adc_key_in  = 0;
#define btnRIGHT  0
#define btnUP     1
#define btnDOWN   2
#define btnLEFT   3
#define btnSELECT 4
#define btnNONE   5

// read the buttons
int read_LCD_buttons()
{
 adc_key_in = analogRead(0);      // read the value from the sensor
 // my buttons when read are centered at these valies: 0, 144, 329, 504, 741
 // we add approx 50 to those values and check to see if we are close
 if (adc_key_in > 1000) return btnNONE; // We make this the 1st option for speed reasons since it will be the most likely result
 // For V1.1 us this threshold
 if (adc_key_in < 50)   return btnRIGHT;
 if (adc_key_in < 250)  return btnUP;
 if (adc_key_in < 450)  return btnDOWN;
 if (adc_key_in < 650)  return btnLEFT;
 if (adc_key_in < 850)  return btnSELECT;
 return btnNONE;  // when all others fail, return this...
}

void setup()
{
  Wire.begin();
 lcd.begin(16, 2);              // start the library
 lcd.setCursor(0,0);
 lcd.print("R.Kasprzak 2000"); // print a simple message

}

void loop()
{
 lcd.setCursor(0,1);            // move to the begining of the second line
 lcd_key = read_LCD_buttons();
 switch (lcd_key)               // depending on which button was pushed, we perform an action
 {
   case btnRIGHT:
     {
     radio.setFrequency(104.4);
     lcd.print("Stacja VOX FM  ");
     break;
     }
   case btnLEFT:
     {
     radio.setFrequency(107.5);
     lcd.print("Stacja RadioZET");
   
     break;
     }
   case btnUP:
     {
     radio.setFrequency(92.4);
     lcd.print("Stacja Pol.1   ");
     break;
     }
   case btnDOWN:
     {
     radio.setFrequency(104.9);
     lcd.print("Stacja Pol.2   ");
     break;
     }
   case btnSELECT:
     {
    radio.setFrequency(104.4);
     lcd.print("VOX FM   ");
     break;
     }
   
 }

}

Kod 2 działa potenciometr ale kłóci się z buttonami.
//Sample using LiquidCrystal library

unsigned char frequencyH = 0;

unsigned int frequencyB;
double frequency = 0;

// define some values used by the panel and buttons
int lcd_key     = 0;
int adc_key_in  = 0;
#define btnRIGHT  0
#define btnUP     1
#define btnDOWN   2
#define btnLEFT   3
#define btnSELECT 4
#define btnNONE   5

// read the buttons
int read_LCD_buttons()
{
 adc_key_in = analogRead(0);      // read the value from the sensor
