προβημα με arduino

καλησπερα, εχω τον παρακατω κωδικο αλλα μου βγαζει το παρακατω σφαλμα που εχω επισειναψει σε εικονα , μηπως γνωρειζει κανεις τι λαθος υπαρχει στον κωδικα? Ευχαριστω

Λογικα λειπει η library Keypad.h.

 

Πανε μια στο menoy σχεδιο -> συμπεριληψη βιβλιοθηκης και εγκατεστησε την.

[arduinowarrior]

το εχω ήδη κανει αυτο.....

[vste]

Για δες λιγο εδω:

http://forum.arduino.cc/index.php?topic=392219.0

 

Λογικα το ενα απο τα 2 void setup που εχεις ειναι λαθος και δεν θα επρεπε να υπαρχει.
