A digital object counter can be used for counting objects. It can used for fun at home for counting objects or people entering inside a room. Since it’s a DIY kit, it can be used for learning basic electronics.

This DIY digital object counter works with TSOP4838 infrared receiver and there are two seven segment displays displaying numbers from 0 to 99. An IR transmitter is oriented towards the TSOP4838 infrared receiver of counter module and objects are moved between the two modules. Each time an object passes between the two modules, the seven segments display show increment in numbers.

Comes as a pack of parts kit and is easily assembled if you can follow the silkscreen indicators(labels) and have beginning experience with a soldering iron. You will need to read the resistor bands or use a multimeter to determine the resistor sizes.
