Digital Clock

Owner: Adit Mugdha Das

A digital clock implemented in Logisim, capable of displaying time in a digital HH:MM format using seven-segment displays. This project demonstrates the use of counters, decoders, logic gates, and a clock generator to simulate a real-time clock.

✨ Features

🕒 Four-Digit Display: Displays time in HH:MM format.

⏰ Clock Signal: Provides a stable timing source for the circuit.

🔢 Counters:

🕑 Minutes Counter: Counts up to 59 minutes before resetting.

🕓 Hours Counter: Operates in either a 12-hour or 24-hour mode (configurable).

🔄 Seven-Segment Display Decoding: Converts binary counter outputs to a human-readable digital format.

🔁 Reset Functionality: Ensures the clock can be reset to its initial state.

🛠️ Components Used

⏳ Clock Generator

Generates pulses to drive the counters.

🧮 Counters

Modular counters for minutes and hours.

Carry-out signals ensure proper cascading between counters.

🗺️ Decoders

Convert binary values from counters to drive the seven-segment displays.

🔢 Seven-Segment Displays

Used to visually represent digits for time.

⚙️ Logic Gates

Handle carry-over, resets, and control logic.

🔐 Flip-Flops

Provide synchronization and state management for the clock.

🧭 How It Works

⏳ Clock Signal:

The clock generator produces pulses that increment the minutes counter.

🕑 Minutes Counter:

Counts from 0 to 59 and resets. Upon reaching 59, a carry-out signal is sent to the hours counter.

🕓 Hours Counter:

Operates in either a 12-hour or 24-hour mode, resetting at the appropriate value.

🔢 Display:

The binary outputs of the counters are decoded and displayed on the seven-segment displays in a HH:MM format.

🚀 Usage

Open the .circ file in Logisim.

Simulate the circuit by starting the clock.

Observe the time updating in real-time on the digital displays.
