7 Segment Counter Circuit

Seven Segment Counter Display Circuit

Description

Here is the circuit diagram of a seven segment counter based on the counter IC CD 4033.This circuit can be used in conjunction with various circuits where a counter to display the progress  adds some more attraction.

IC NE 555 is wired as an astable multivibrator for triggering the CD 4033.For each pulse the out put of CD 4033 advances by one count.The output of CD 4033 is displayed by the seven segment LED display LT543.Switch S1 is used to initiate the counting.Diode D1 prevents the risk of accidental polarity reversal.

    can u please give me the introduction and literature survey of visitor counter using IR sensor and 2 seven segment .

  • prakhar pandey says:

    Sir,
    Here 555 ic is wired as monostable mode.
    And you have written it in astable mode.
    Please make sure. And also if it is in astable mode then what will be the value of resistor between pin 6 and 7.

  • James says:

    Does anyone know how I can make a circuit that as an object passes between a beam of light the display goes down by one and when I press a button the display resets to 9. I have in idea for how I can use his but don’t have a clue how to make it, any help would be great, thanks.

  • Puja says:

    can i use 4511 instead of 4033

  • KK says:

    when i connect battery,the display blinks n turn off,can anyone give me the solution please?

    • To correct this fault, connect pin no. 15 of 4033 to the ground, because it is reset pin and if we leave it open then it behaves in the same manner as you mentioned.
      With this pin you can do one more thing, you can connect 220 Kohm resistor between pin 15 and Ground(0V). Now if you apply high voltage (5V) to the pin 15 then your display will reset.

    Requirement;-To read & monitor my Battery voltage which starts from-0 to 24vDC. It should indicate or display on Red color LED display to having in built in circuit which i will be using in my units on front side.My I/P will be either 12 or 24 volts D.C.to this unit. 25pcs/month on regular (red color) & the same in green color.Type -Panel mount. Pl contact me on above mail id for more details.

    Regards.

    I find a circuit of 4 digit display,i welcome any one who know it to help me

  • Rajat says:

    wow!
    thanks for your help
    such a great project to make!!!!!

  • aki says:

    what changes need to be made if inplace of CD4033 , HCF4033 is used.

  • aki says:

    What are the alternatives for cd4033 in this circuit, plz reply.

  • marianne says:

    is it works very good in terms of counting? is sensor present in your project?

  • Ashish says:

    no problem…got the solution!! :)

  • Ashish says:

    Hello..i have modified this circuit a little bit by combining the digital dice circuit and this one..i have used ne 555 timer as the multivibrator, cd 4017 as the decade counter, cd 4033 as counter and LT 543 as d seven segment..i hav used 6 leds…the problem is dat wen I press d push button..the following happens..wen the 1st LED is ON..it displays ’0′ in d seven segment..wen the 2nd LED is ON..it displays ’1′ in d seven segment..wen the 3rd LED is ON..it displays ’2′ in d seven segment..and so on..plz help..i am still in the 12th std. and wud appreciate any help..it wud be also gr8 if sumone cud tell me d diff between cd 4017 and cd 4033..

  • Tittu says:

    HI Surya,
    pin out Diagram is illustrated below

    LT543 is a common cathode display.
    So dont forget to ground its 3rd pin

    Pinout of 7 segment display
    a-7
    b-6
    c-4
    d-2
    e-1
    f-9
    g-10
    5-dot (no need here)

  • Tittu says:

    Yes, You can increase the number of 7 segment display(bits) by cascading cd4033 ic…. You will get an idea about it from here

    hi,can i use this to integrate with motion sensor hobby kits and i want to count every person that enter count?please rply asap

  • Mas. says:

    Can someone please give me a circuit diagram that uses 74LS47 and 74LS90 instead of CD4033.. Thanks in advance. Please reply as soon as possible. I’ve been trying to search for it but can’t seem to find it.

    I Built the TTL( 555/7447/7490 Version) in College,,, I like The CMOS Version Better!!! Thanks So Much.

  • seetharaman says:

    Hi Daine you can use the following circuit appeared earlier in our columns. use less number of counter ICs as per your requirement

  • Daine says:

    hello, my name is Daine. I’m wondering whether it is possible to make the circuit count backwards say from 9 down to 0?
    cheers

  • Michael says:

    I am looking for a circuit that has three 7 segment LED displays, with a potentiometer. The circuit must make the 7 segment display to show “000″ when the potentiometer is at lowest value and “200″ at maximum value. I would also like it to be remote control witha range of about 20 meters. Any information would be great.

    Thanks for any help I get.

  • Terminals are not marked on the IC. how do I find no.1 and so on?

    • John Ross says:

      One pin 1 location can be located by looking for a notch at one end of the chip. Turn the chip so that the notch on the chip is facing left. Now look at the lower left side of the chip, that will be #1 pin and the numbers will be sequential from that point to the end of the pins in that row. Another identification of pin #1 is to see a dot at one end of the chip. Turn the chip as in the instruction above and see pin one in the same place, (lower left side) pin #1.

  • SUMON DAS says:

    hi.
    i am sumon.i study diploma in electronics.i follow this ckt & i satisfied

  • I need an electronic circuit to display the two-digit seven-segment display, which displays the numbers 01 to 99 on every odd count touch (1, 3, 5 and so on), using a touch switch plate. As detailed steps:
    - touched the first time, displaying the numbers 1;
    - touched the third time, displaying the number 2;
    - touched the fifth time, featuring the number 3;
    - touched the seventh time, showing the number 4. And so on.
    Can anyone help? Thanks!

    thanks thanks

  • seetharaman says:

    Yes Ravichandran it has got market potential in India as most of our indoor games require it, provided you can match the brass variety or may be little costlier. you may have to produce in very large quantity to maitain low price. better to ofload your idea to some taiwaneese co and get the chip and display from them. you cant just match their price and quality.
