New questions..
I need to limit the range of the values to between 0 and 127. Basically two pairs of up/down counters, where two button take the values up and two buttons take the values down, one pair per value. At the moment I'm having trouble once I go below 1. the up button then starts from double digits e.g. 11 or 21.
I was able to get to MAX 127, cleared the unused characters with
lcd.print(" ");
but comming up from -1 causes a problem. Also when coming down from 127 I get up to 999 after 100 coming down. So clearly this isn't the best way of doing this. Like I said before the larger project for which this intended has no delay (is a musical instrument) and the timer prescaler isn't the default ,in order to maximize the analog reads. So "delay's" are no good. Can I poll the button pins, put the values 0-127 in an array and do the increment/deincrement that way and what might that code look like?
