Dear all,
Hi to all,
My query is, recently i tried to interface 4x4 matrix keypad to the PIC16f877a controller and i found that my keypad buttons are getting automatically pressed whenever i make movement of keypad, to resolve and crosscheck this problem i have purchased a new keypad but still it is giving same problem. i hope the problem may be inside the keypad, but i don't know exactly what is the problem. If any one can suggest remedy to my problem i will be very thankful to him.
