Simple HND project
Hi
I have just started with my project, i am trying to send a code from a keypad across infra red to a 7 segment display and and maybe open a lock if the right code is entered. Anyway the problem is i have a keypad (connected 4x3 format) and want to hook it up to a pld that i can program, however am not sure how to power the keypad without applying a logic 1 to the pld. Can anyone give me some advice on how to do this please. |
