Matrix Voltage Divider Button Calculator for Microcontrollers

Uses Greedy-Best-First-Search algorithm to determine viable solutions to complex voltage-divider resistance combinations that will allow a microcontroller to control variously sized button matrices using only 1 analog input pin. Cut-n-Paste app-generated Arduino code to quickly and easily include button-matrix into your project. Sweep-And-Prune system of objects create interactive bitmaps user-interface.
