Lesson 9: Design A 4-Bit Counter
A great strength of digital circuitry is that the clock can act as a timer or counter with appropriate flip-flop circuitry in place. In this lesson, using some LEDs, we will learn how to build a 4-bit binary counter that uses the clock input to tell our circuit to increment a counter with every clock period.
