Hello. I looking for some smart solutions to clear "0" on my LCD when decrement value.
if ((*var == 9) || (*var == 99) || (*var == 999) || (*var == 9999)) lcd.print(" ");
I currently use something like that but its depending on var type and range. Earlier I just erase all digits but then i have to be careful to not erase other things and it also cause blinking my value. So are there any better solutions that will not consume so much resources?
