AnalogKeys is an arduino library that allows you to easily manage the keys on an lcd shield that uses an analog input for the keys.
It allows you to calibrate the keys on the fly instead of having to preprogram the keys. But it does allow you to still use preprogrammed values if you prefer.
How to use
An example on how to use this library is included.
In order to see it open the
sketch menu option when in the arduino ide.
Then go to
import library and click on
add library. Then in the folder
window navigate to where you have saved the
AnalogKeys folder and select it
then press open.
You can then go to the
File menu option and go to
examples. Then go to
AnalogKeys and finally click on AnalogKeysExample. A new window will open in
which you can see the example sketch.
