It will be designed with flip-flops and logic gates. It will count and repeat in the forward direction as 0,1,2,3, ..., 9 or backward as 8,6,4,2,0. The count will be determined by a button or switch. 7447 can be used as a code converter between the counter and the 7-segment display. The clock input of the circuit will be fed by a square wave oscillator made with the 555 IC. please help me thank you........
