You can use this 3 digits digital object counter for counting objects or people entering into a room. It can be used by engineers for learning about digital counters.

This DIY digital object counter works with a photoresistor and there are three seven segment displays displaying numbers from 000 to 999.

Works with a laser module

Turn on the laser module and direct it towards the photoresistor and hit the photoresistor with the laser beam so that whenever the laser is blocked, the counter would count.

The counter module works with 5V. You just need to power up the kit using a 5V mobile charger or any other power adapter.
