is like an "ilussion" or trick to set a decimal dot, if there wasn´t decimal dot max value would e 1023 intead of 10.23 ,
i want to test lm35, if somehow with some math functions or some ladder tricks can we managed to visualize temperature with lm35 in decimal values?
here Jonathan Westhues explains a solution using lm35, i tested that before, it works, but only integer number can be shown in lcd
