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.
