Programming my own pick by light system

Programming was simple on Arduino UNO.
External programming language is AutoIt V3 to control the COM#.
There are no LEDs in yet but the working relays will do it for now.

What did you start coding it on? Was there a base code you started off with? I really wanna make one of these
