Hi,
I'm new to Programming. After a hour of searching i didn't find a answer.
How can I raise a value on a key press?
I like to add (and on another button subtract) a 1 to the "steer"-value, to calibrate my steering for my RC-car which is attached via XBEE to Arduino.
I hope someone can help me.
btw: sorry for my bad english
