I am re-posting the question to see the solutions of different experts. If you have already solved the question, please do not answer it again, let another expert answer it. Design and implement a presettable 4-bit down counter similar to a kitchen timer. The counter allows any 4-bit data to be loaded as the initial value using a preset circuit. When the counter reaches 0000 , it stops, and a LED or buzzer is activated. After loading the preset value, the counter starts automatically. The clock signal generation and clock period are to be determined by the student. Any flip-flop type and logic gates can be used. A 7-segment decoder can be used for displaying the input and output, with switches and LEDs utilized for input and output visualization.
