    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.
