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.

I find a circuit of 4 digit display,i welcome any one who know it to help me
wow!
thanks for your help
such a great project to make!!!!!
what changes need to be made if inplace of CD4033 , HCF4033 is used.
What are the alternatives for cd4033 in this circuit, plz reply.
is it works very good in terms of counting? is sensor present in your project?
no problem…got the solution!!
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..
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)
Yes, You can increase the number of 7 segment display(bits) by cascading cd4033 ic…. You will get an idea about it from here
mycircuits9.blogspot.com/2012/03/wireless-mains-voltage-counter.html
can someone suggest the idea i.e on my college told to implement it using four 7 seg display
Can any body to illustrate pin diagram in refrence to abcdef and 123 of LT543 ,7 segment display LED
Thanks

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
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.
Hi Daine you can use the following circuit appeared earlier in our columns. use less number of counter ICs as per your requirement
http://www.circuitstoday.com/up-down-counter-circuit
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
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?
hey frnds,i want to make a project using cd4033,555timer,7segment display and want’s to give trigger to 555 by LDR and LED as when beam will cut ,555 should trigger and give a count..plz can anybudy help me out hw to implement this…………..???????????/i need it in 2days plzzzz….thanksss………
Hi Zakaria use set / reset flip flop before the counter it will take care. first touch it will get set second touch it will get reset third touch it will get set etc.
plz give the layout of seven segment counter its very important for me so plz help
dear recently we have designed a seven segment visitor counter just by using simple components rather than micro-controler. if u want the circuit diagram so e-mail me at (engr.ferozkhan@yahoo.com)
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!
Hi, just a small enquiry.
I am using the PIC18f4520.
How do i count my dual seven segment from 0 -60 and stop?
I would like to know the coding for this function.
Yr help would be much appreciated.

i ws lukng for layout of 7-segment BCD counter…
pls help me!!
Hi Kumar it is just a up counter from 0 to 9 and restart again that is all. Pl refer data sheet
http://www.datasheetcatalog.org/datasheets/134/108993_DS.pdf
I do not find the up counter, with clock and reset as the input port and Cnt and Hit as the output port in pspice-capture CIS. Please help me.
thanks thanks
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.
