One of the most basic building blocks of electronic computers is the binary number system. This kit counts in binary numbers and displays the binary number by red LEDs. A LED turned on is a 1 and off is a 0. This kit provides an easy to understand display of the binary number. The counter increases by 1 number each time the button is pushed. It also can count automatically by holding the button down. Teaches logic principles and binary counting. This kit features 7 red LEDs count button clear button and 2 IC circuit. Counts from 0 up to 127 in binary numbers. Can be used alone or can be connected to the C6360 Decimal Display Kit which displays the decimal number equivalent of the binary number.
