# what is counter and how does it work?

## what is counter?

before we discuss about how to make a counter and what are the counter types then first admin will explain in advance about what is counter

Counter is an electronic device that it’s can be used to calculate the number of incoming pulses through its input

This device comprises one or more flip-flops arranged in such a way that each input pulse will add a chunk value. so you must read the previous article about flip-flop

counter types consist of various kinds of them are up counter, down counter, up down counter and counter modulo n

In everyday life An example of a counter is on a digital beads

In digital beads every you press the button then the value on the screen will increase

The more you press the button then the value will increase more and more

## how to make a counter circuit?

Counter or counter is a digital device that serves to calculate the number of inputs that enter

Counters can be made using d flip-flop or jk Flip-flop

## what are the counter types?

There are so many counter. The types of counters according to the count

According for how it calculate the counter is divided into several types of counters which are as follows

### Up counter

Up counter is a series of counters that function counting up. An example of an up counter is on a digital beads like the example above

set up counter can be made by using D Flip-flop or JK Flip-flop. Here is a scheme of a series of up counters using JK flip-flop

### Down counter

Down counter is a circuit that serves count down

Counter of this type can be met at the traffic light where the numbers will count down to number 0. The example scheme is as follows

### Counter modulo N

Counter modulo N is a counter circuit that serves to count up to a certain number

The types of counters according to the arrangement of the circuit

### Syncronous counter

In syncronous counter clock is done simultaneously

### Asyncronous counter

At the asyncronous counter clock is obtained from the output in the previous circuit

Counter circuit simulation

Counters can be made using d flip-flop or jk flip-flop

To make the counter circuit will be easier if you do simulation using proteus software or by using Android application

All the above circuits can be simulated in proteus software
