3 Digits Digital Objects Counter

This three-digit digital object counter is an ideal tool for counting objects or people entering a room. It’s perfect for engineers looking to learn about digital counters through a hands-on project.

Overview

The DIY digital object counter uses a photoresistor and three seven-segment displays to show counts ranging from 000 to 999. It operates in conjunction with a laser module, making it a practical and educational device for various applications.

How It Works

1. Laser Module Integration:

   • Turn on the laser module and direct the beam toward the photoresistor.
   • Ensure the laser beam consistently hits the photoresistor.
   • Each time the laser beam is interrupted, the counter increments by one.

2. Power Requirements:

   • The counter module operates on a 5V power supply.
   • You can power the kit using a 5V mobile charger or any compatible power adapter.

3. PCB Dimensions:

   • The printed circuit board (PCB) measures 43 mm by 58 mm, making it compact and easy to install in various settings.

Features

• Transmitter-Receiver Distance:
  • The distance between the laser transmitter and the photoresistor receiver can be up to 10 meters.
• Reset Functionality:
  • The counter module can be reset to zero at any time, allowing you to restart the counting process as needed.

What's New?

• High Stability Output:
  • The updated kit offers highly stable output with no false counts, ensuring accuracy and reliability.
• Simplified Design:
  • The kit now exclusively uses a photoresistor, eliminating the infrared feature for a more streamlined design.

This digital object counter is a versatile and educational tool, making it an excellent addition to any engineer's toolkit or learning curriculum.
