Introducing the DIY 3-Digit Digital Objects Counter, meticulously designed by Sagar Sapkota. This innovative counter utilizes a photoresistor and a laser transmitter module to precisely count objects. Here’s how it works:
The laser transmitter projects a beam onto the photoresistor. Each time an object crosses the laser path and interrupts the beam, the counter increments the count by one. This device is capable of counting from 001 to 999, making it versatile for various applications.
The counter is equipped with a test switch for easy verification of the count. It features common cathode seven-segment displays for clear and accurate readouts. The core components include the CD4026 decade counter and the NE555 timer, ensuring reliable performance.
