But i wanted to test it on LCD without i2c, i changed the codes ( the libraries , void setup begin part, and backlight) and also changed the pins connection - RS = 12, en = 11, D4 = 5, d5 = 4, D6 = 3, D7 = 2 (LCD pins to Arduino Pins). The outcome is the LCD shows the alarm mode straight away and when i press the set button, the mode changes then goes back to alarm mode rapidly, the buzzer is ringing all the time as well. Do you know what's wrong with it?
