Sections of RS7473 dual flip-flop are connected to form simple counter that counts to three in binary with LEDs, By adding more flip-flop stages, count can be extended to higher values. If OFF LED represents 0 and ON LED is 1, combinations 00, 01, 10, and 11 rep-resent 0, 1, 2, and 3, respectively. Input is restricted to low audio frequency so LED changes can be readily observed during demonstrations. -F. M.
