The Clocked SR flip flop is one of the most fundamental sequential logic circuits in digital electronics. Unlike basic SR latches, a clocked SR flip flop circuit uses a clock signal to control when state changes occur, making it essential for synchronous digital systems. This comprehensive guide covers the clocked SR flip flop truth table, circuit diagrams using both…

A counter is a device which can count any particular event on the basis of how many times the particular event(s) is occurred. In a digital logic system or computers, this counter can count and store the number of time any particular event or process have occurred, depending on a clock signal. Most common type of counter is sequential digital logic circuit…

An asynchronous counter (or ripple counter) is a sequential digital circuit in which the outputs of flip-flops are connected in series, so that the output of one flip-flop serves as the clock input to the next stage. Not all flip-flops may change state at the same time as synchronous counters, so asynchronous counters are easier to design but may experience propagation delays.

Object counters or product counters are important applications used in industries, shopping malls, etc. They count objects or products automatically and so reduce human efforts. In this tutorial we are going to design a simple object counter circuit without using any microcontroller.

In this tutorial we are going to design a 0-99 counter by interfacing two seven segment displays to ATMEGA32A Microcontroller. Here we count events based on number of times button is pressed.

Before moving ahead, let's understand what is a seven segment display. A seven segment display got its name from the very fact that it has seven…
