Hello everyone, I'm making a project where when you press a button, the number on the LCD increases by 1. My issue is when the Arduino starts, the LCD is empty, as soon I press the button the LCD shows the wanted number already summed up with 1, but, pressing the button again, nothing happens at al…

Addition of numbers using button won't work

Do you have a pull-down resistor on pin 2?
