HI all. First off sorry if I'm posting in the wrong forum section. I wasn't really sure which would be best, if this isn't the correct one please move my topic.
I'm working on a small project where I am using the arduino's analog read to read the voltage from a potentiometer. I have taken this voltage and mapped it to values between 0-25 for letters to be displayed on an LCD screen. It works pretty well the only problem I'm having is that when turning the potentiometer it tends to be too sensitive and the letters change to easily requiring very precise touch.
My question is how can this be fixed so it will move more smoothly/less sensitive through the letters? The only thing I can currently think of is that maybe the arduino doesn't have a high enough resolution to switch between 25 values? Otherwise maybe there is a different type of potentiometer I should be using?
Thanks for taking a look. If you need me to post code I can do that too.
