HOW TO USE IT
Use the number-of-bits slider to set the number of bits that the counter can hold. Now press the setup button to change the number of bits displayed. This will zero all the bits.The slow-motion slider is an easy way to adjust the speed of the display so you can watch the bits change as the red arrow moves. Set it to zero if you want to quickly count to a large number.
The increment button adds one to the bit pattern, using rules that work well when the number is positive.
The loop button will continuously increment the counter until clicked a second time.
The four monitors display the decimal equivalent of the bit pattern, assuming that the bits have been stored using each of the four different data representations.
To take a quiz, first select the quiz topic, and then click the quiz button. You may choose to include commas or spaces in your answer to help you count digits; they will be ignored. If you choose "random" for your quiz topic, then one of the other possible quiz topics will be chosen for you.

The applets made with NetLogo require Java 1.4.1 or higher to run. The applets made with NetBeans require Java 1.4.2 or higher to run. Applets might not run on Windows 95 or Mac OS 8 or 9. You may obtain the latest Java plugin from Sun's Java site.
