This project demonstrates a base 5 number system using non-numeric symbols. The odometer displays the value of the symbols being shown. You can either manually set the symbols on the odometer using the (+) and (-) buttons, or you can have it count automatically in base 3 by clicking the "go" button. This is very similar to the odometer widget on the code.org website.
This is a submission by AP Computer Science Principles student 21schmgab1. It is an example of a base 5 number system that uses non-numeric symbols to represent value.
