Up Counter

We can use this circuit to make digital object counter. It can be used as a divide by 10 counter by connecting Q A with clock input2, grounding all the reset pins, and giving pulse at clock input1.

Thus this system can count from 0 to 99 and give corresponding BCD outputs. Output 1, BCD Output bit 0.
