3 Digits digital objects counter SMD | BuildCircuit.COM

Here’s a rewritten and explained version of the description:

This is a Surface-Mount Device (SMD) version of a 3-digit digital object counter designed by Sagar Sapkota.

How It Works:

• Detection Mechanism: The counter utilizes a photoresistor and a laser transmitter module. The laser beam emitted from the transmitter hits the photoresistor. Whenever an object obstructs the laser beam, the counter registers this interruption and increases the count by 1.
• Counting Range: The counter displays numbers from 001 to 999.
• Testing Function: A test switch is included on the counter to manually test the counting functionality.

Components:

• Displays: It uses common cathode seven-segment displays.
• Integrated Circuits: The circuit is built using a CD4026 decade counter and an NE555 timer for accurate counting and timing.

Availability:

You can purchase this kit from https://www.buildcircuit.com/product/… . There are two versions available:

1. DIY Kit Version: For those who prefer assembling the kit themselves.
2. Fully Assembled SMD Version: For those who prefer a ready-to-use assembled counter.

This description highlights the functionality, components, and availability of the digital object counter in a clear and organized manner.
