Keypad: Values from array

$

0

Hello! Im pretty new to labview and wondering if anyone could help me out here.

 

I have a 4x4 keypad wired up to labview using the NI myDAQ.

 

My code has 2 parts so far, first is the 'scanner'. This scans the key pad drom presses and returns the value pressed as a string.

The second part is 'memory' This part puts the presses recorded in scanner and records them in an Array.

 

What im trying to get is a keypad to light a boolean LED when the correct 4 digit code is pressed in the keypad. I am hoping that someone will be able to understand what i have done and what i am trying to acheive here. I realise that they paths i have taken in getting to where the code is may not be the best but i have been learning as i go.

 

Thanks, Thomas
