Hi Where is the mistake, after turning power off/on i always is 157 ? #include <EEPROM.h> #include <LiquidCrystal.h> LiquidCrystal lcd(12, 11, 5, 4, 3, 2); void setup() { // int i; int i = EEPROM.read(0); Serial.begin(19200); lcd.begin(16, 2); pinMode(buzzer, OUTPUT); //setting up…

Thanks for support, problem solved
