Using Arduino Programming Questions
#1

Hello everyone!
Sorry for my bad english…
I’m trying to control brightness of led light with arduino and I want to display brightness precentage on 16x2 I2C lcd. The problem is, that 3 character number doesn’t display correctly (look at the photos).
If anyone knows how to program arduino so that the number will appear correctly, please let me know.

You need to pad the number with spaces. If you print “100%” to the display and after that print “99%”, the display will show “990%”.

lcd.setCursor(0, 1);
if (brightness < 100) lcd.print(" ");
if (brightness < 10) lcd.print(" ");
lcd.print(brightness);
lcd.print("%");
