Introduction: Infrared Based Digital Object Counter DIY Kit

I have made a simple infrared based digital object counter. 

There are two kits in this project, one is counter module and the other is infrared transmitter module. 

The modules face each other and whenever an object is moved between the two modules, the counter module counts the movement.

About counter module: The counter module works with CD4026 chips and it counts 0-99. The counting process can be reset and dropped to 0. It has an infrared sensor TSOP4838. 

About Infrared transmitter module: The infrared transmitter module works with NE555 timer. The circuit has been configured to transmit IR signal at frequency approximately 38Khz. It operates in astable mode of NE555 timer.

The kit can be used as a remote tester also. 

Take any kind of TV/DVD remote control and operate the kit.

The object counter kit can be used for counting people entering inside a room or counting any kind of objects. 
The distance between the transmitter and counter module should be around 1 meter.
