This video demonstrates a 1-9 counter circuit using a 7448 BCD-to-7-segment decoder and a 7-segment display in Proteus Software. The circuit counts from 1 to 9 with each button press, ideal for learning digital logic and display interfacing.

Key Features:

7448 BCD-to-7-Segment Decoder: Converts BCD (Binary-Coded Decimal) signals to 7-segment display outputs.
7-Segment Display: Shows numbers 1–9 with bright blue LEDs.
Current-Limiting Resistors (200Ω): Protects LEDs from overcurrent.
Button Control: Increment the count by pressing the input button.
No Microcontroller Required: Pure digital logic for learning core electronics principles.
How It Works:

BCD Input:
A clock signal (e.g., button press) increments the counter (e.g., 7490 IC, not shown here).
The counter sends a BCD code (4-bit) to the 7448’s input pins (A-D).
7-Segment Conversion:
The 7448 decodes the BCD code to activate specific segments on the display.
Example: BCD 0001 → Lights segment "b" → Displays "1".
Counting Sequence:
Each button press advances the count (1 → 2 → 3 → ... → 9).
After 9, the circuit resets to 1 (or 0 if not modified for 1-9 range).
What you’ll learn:

How BCD codes work with 7-segment displays.
Role of the 7448 in simplifying display interfacing.
Current-limiting resistor calculations for LED safety.
Simulating real-world circuits in Proteus.
⚠️ Note: This circuit is simulated only. For real-world use, add a debouncing circuit to the button input.
