Practical case: 2-Bit Binary Counter with End-of-Cycle
Level: Basic – Build a 0 to 3 binary counter with manual clock, reset, and a maximum count indicator.
Practical case: Open door alarm with inhibition
Level: Basic – Design a logic circuit using a 74HC00 NAND gate to trigger an LED alarm only when the door is open and the system is enabled.
Practical case: Emergency stop system
Level: Basic – Use the low-level output of a NAND gate to stop a process if two sensors detect danger simultaneously.
Practical case: Logic inverter using NAND gate
Level: Basic – Demonstrate the universality of the NAND gate by configuring it as a basic NOT gate.
Practical case: Dual Input Alarm System using OR Gate
Level: Basic – Build an alert system that activates a warning LED when either a local or remote signal is triggered.
