How to make a digital object counter using, infrared sensor, CD4026 and seven segment display

We are now selling CD4026 and CD4029 up and down counter modules.

Description: This is a simple object counter circuit that counts from 0 to 9. You can make this project using four different modules listed below:

Follow these steps:

a. Connect collector pin of infrared remote tester to positive terminal of electrolytic capacitor of RC module.

rc-AND-ir2

b. Connect counter module to RC module. Connect collector pin of transistor (in RC module) to pin 1 of 4026B.

    This is 3 digits digital object counter kit for electronics beginners and hobbyists. It is the upgraded version of our previous 2 digits and 3 digits object counter.

    You can use this 3 digits digital object counter for counting objects or people entering in a room. It can be used by engineers for learning about digital counters.

    This DIY digital object counter works with VS1838 infrared receiver and photoresistor and there are three seven segment displays displaying numbers from 0 to 999. An IR transmitter is directed towards the VS1838 infrared receiver of the counter module and objects are moved between the two modules. Each time an object passes between the two modules, the seven-segment displays show increment in numbers from 0 to 999.

  1. I have already made the circuit but its not working . I think the problem is the ir sensor . because the rest of the component is working .

  2. sir, i have question on these can u help to answer me ?

    1. The seven segment display can i use the pin are in horizontal form?

    2. The infrared detector, must i use exactly as TSOP4838?

    3. Can the counter start from 0?

    Thank you

      1. Sir thx for your answer but now when i start work on it i found some new question would u answer me again?

        1. First, all my module (RC,infrared detector and counter) can work independently but when i connect all together, the LED of my RC module and infrared detector will light up. I thought it will only bright up only when receive IR. Is that my circuit connection problem?

        2. Then for the counter, the seven segment when connect to 4026B is it only show 8. And it will only start counter when i connect to some other module such as 555 timer
