Objective:
Create an app that calculates the resistor values of different resistor color combinations, functionality to clear the calculator and backspace.
Problem:
How do we make it possible for the user to only delete one color?
Solution:
We created a system that keeps track of which color band the user is on. Upon user clicking on the calculator’s backspace it will reset the color of the band, resets the value of the number and move the user’s band position one back.
