Hello to all! I'm currently making a schematic diagram of a 3 bit binary incrementor and is not sure if it is a incrementor. (using a switch)
If i input:
0 0 0 = 0 0 0
1 0 0 = 1 0 1
1 1 0 = 1 1 1
1 1 1 = 1 0 0 0
It's like the draft adds one bit on my input

Until i saw a video where every time he press a button, a bit increments 1 bit. 000 -> 001 -> 010 -> 011 -> 100 -> ... -> 111
and i want to change my current draft into this and currently using 74xx IC? Can someone enlighten me if these IC can do these?

What you are trying to build is called a binary counter.
You can do this using what is called a t-type flip-flop or you can build what is known as a time-state machine.
You will need to debounce your push-button.

I see, but my first draft was a binary incrementor am i right?

 

Among others the 74192 SYNCHRONOUS 4-BIT UP/DOWN COUNTERS (DUAL CLOCK WITH CLEAR) comes to mind. Using a push button you can either increment (count up) or decrement (count down) the count. The push button(s) serve as the clock and you can count to N and reset where N is your choice. You can also build a binary counter using discreet components but a single chip like the 74192 is a simpler solution.

What's the difference between a counter and bit incrementer? Things got mixed out.

Depends on the counter. Some counters like the 74HC4017; 74HCT4017 Johnson decade counter with 10 decoded outputs are decade counters with a decimal output. Some counters only increment with incoming clock pulses and some will decrement. Since you mentioned binary I suggested an Up / Down counter with a binary output. A simple 4 bit counter can be built just using a few flip flops like the CD4013 D flip flop as an example. CD4013B CMOS Dual D-Type Flip-Flop. Here is another example using the term bit counter. 74HC163 is a bit counter which outputs in binary.

Depends. Semantics maybe.

A binary counter can be considered to be a sequential circuit or a time-state machine, i.e. it assumes a new state following a clock signal.

A bit incrementer can be considered to be a combinational circuit, where the 4-bit output is a static function dependent on the static logic level of 5 inputs.

 

That does not look much like a logic chip, but it does look a lot like a microcontroller.

1. Get a microcontroller
2. Connect the LEDs and switches
3. Write your code to get the function you desire, including button debouncing.
