This project is a base 3 odometer that counts up/down using a base 3 number system and displays the value of the numbers being shown. You can either manually set the numbers 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.
Thanks to paulfuller75 for the original odometer simulator. I have adapted it to be a base 3 number system and added a "value" variable and calculation
