hello at all,
does anyone have an idea how to get from a 4x4 matrix keyboard (Keypad.lib) a 2 or 3 digit value can be read?

Kiss(The program should wait until the value is read)

Best regards
kwalter

hi, The keypad library is included with Wiring, check the Sketch ->  Import library menu. You can find examples and reference for it here: http://www.arduino.cc/playground/Code/Keypad
Let me know.
