I am working on a project that requires me to use a 3x4 keypad to put a number on a 7-segment display. I am trying to figure out what chips i need to use to be able to press a number on the keypad and have that number locked in and be able to press other numbers with out it changing the numbers until i reset the circuit. I believe i need an encoder, 4bit register, and decoder between the keypad and the 7-segment display but dont know which ones to use. Can anyone help me please?
