Practical case: Sensor fault detector
Level: Basic – Implement an XOR gate circuit to activate a visual alarm when two redundant sensors present different logic states.
Practical case: Security alarm with NOR
Level: Basic | Objective: Verify the NOR gate truth table using an alarm circuit that activates only when no sensors detect movement.
Practical case: NE555 Delay-On Timer for READY Indicator
Level: Basic – Build an RC-timed delay circuit to activate a READY indicator seconds after power is applied.
Practical case: Alarm Lockout Logic with NAND
Level: Basic – Build an active-high alarm indicator using 74HC00 NAND gates to understand universal logic and signal inversion.
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.
