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.
b. Connect counter module to RC module. Connect collector pin of transistor (in RC module) to pin 1 of 4026B.
c. Orient infrared transmitter towards infrared receiver module. Whenever you block the infrared beam, the circuit starts counting.
Use infrared LED in infrared transmitter. HOW TO MAKE AN INFRARED TRANSMITTER?
