What is an object counter?

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.

What are the different types of counters?

Types of Counters

  • Asynchronous Counters.
  • Synchronous Counters.
  • Asynchronous Decade Counters.
  • Synchronous Decade Counters.
  • Asynchronous Up-Down Counters.
  • Synchronous Up-Down Counters.

How many types of counters are there?

4. How many types of the counter are there? Explanation: Counters are of 3 types, namely, (i)asynchronous/synchronous, (ii)single and multi-mode & (iii)modulus counter. These further can be subdivided into Ring Counter, Johnson Counter, Cascade Counter, Up/Down Counter and such like.

What is digital object counter?

The object counter is made up of sensor, counter and display. · Sensor senses any object that passes in front of it and gives output pulse to the counter. · Counter increments count by one when it gets pulse input from sensor. · Current count is displayed on any type of display like the 7-segment or LCD display.

How many basic types of counters are?

Counters are of two types. Asynchronous or ripple counters. Synchronous counters.

What are electronic counters?

An electronic counter is a sequential logic circuit which has a clock input signal and a group of output signals that represent an integer “counts” value. Upon each qualified clock edge, the circuit will increment (or decrement, depending on circuit design) the counts.

What is Johnson’s counter?

A Johnson counter is a modified ring counter in which the output from the last flip flop is inverted and fed back as an input to the first. It is also called as Inverse Feedback Counter or Twisted Ring Counter.

What are different methods of countering?

What is ripple counter?

Ripple counter is a special type of Asynchronous counter in which the clock pulse ripples through the circuit. The n-MOD ripple counter forms by combining n number of flip-flops. The n-MOD ripple counter can count 2n states, and then the counter resets to its initial value.

Can I design an object counter circuit without a microcontroller?

In this tutorial we are going to design a simple object counter circuit without using any microcontroller. The circuit diagram of object counter is quite similar to my previous project ( digital stopwatch circuit) but a little complex .

What is door entry person counter project?

Here is the circuit Diagram Of the Door Entry Person Counter project, This object counter circuit is used as a Digital Object Counter using a Two Digit Seven Segment LED Display. This can also be called People or Object counter Circuit diagram using IC 555 and IC 4033 or Digital IR Counter to Count Door Entries.

What are the components of a 2-digit counter?

The given circuit is a 2-digit counter so it counts 100 counts from 0 to 99. As shown in circuit diagram the major components of circuit are sensor, decade counter cum display driver chip CD4026 and common cathode type 7-segment display. · The IR LED and photo diode together are used as object sensor.
