I'm new to this forum, but have some understanding of C.
First of all, can you program the Arduino(duemilanove) to read the keypad (basic number keypad as pictured on the site) from each pin?
If so, can I do this when I program to write the "code" send out a high? (to unlock whatever it is with the keypad)
int code0 = digitalRead(10)==HIGH; int code1 = digitalRead(2)==HIGH; int code2 = digitalRead(4)==HIGH; int code3 = digitalRead(6)==HIGH; int code4 = digitalRead(8)==HIGH; int code5 = digitalRead(12)==HIGH;
Entire code is attached if someone doesn't mind giving me any ideas.
