Circuit Diagram – Digital Visitor Counter Using IC 4026

The Digital Visitor Counter is an electronic device designed to count and display the number of visitors to a particular location. It utilizes a Digital Counter IC (such as the IC 4026) and a 7-segment display to show the count in a clear, easy-to-read format. This project is ideal for applications like counting foot traffic in stores, monitoring event attendance, or tracking any other form of traffic where numerical recording is needed.

Components Needed

• IC 4026: A decade counter IC that drives the 7-segment display.
• 7-Segment Display: To visually show the count.
• Pushbutton: For incrementing the count.
• Resistors: For current limiting and pull-down purposes.
• Capacitors: To filter noise and stabilize the circuit.
• PCB (Printed Circuit Board): For assembling and securing components.
• Power Supply: 5V DC to power the circuit.

Digital Visitor Counter : How It Works

The IC 4026 is a decade counter that can drive a 7-segment display to show digits from 0 to 9. Each time the pushbutton is pressed, the IC increments the count by one. The count is displayed on the 7-segment display, which is controlled by the IC.

In the circuit, the IC 4026 counts the pulses generated by the pushbutton. When a button press is detected, the IC updates the display to reflect the current count. Capacitors and resistors are used to ensure stable operation and prevent noise from affecting the counter.

Assembly

The circuit is assembled on a PCB to create a compact and durable design. The PCB layout includes all necessary connections for the IC, display, and other components, ensuring a reliable and long-lasting counter.

This Digital Visitor Counter project provides a practical application of digital counters and display technology, showcasing how to build a functional and user-friendly electronic counter system.
