Basic Level
- Practical case: Dual Safety Motor ActivationLearn Digital Electronics by building a safety circuit with a NAND gate. Create a two-hand motor control system that activates 5V output only on dual press.
- Practical case: Veto Voting SystemMaster Digital Electronics by building a voting system using a single 74HC00 NAND gate IC. Create a safety interlock circuit where LED output signals approval.
- Practical case: Water tank level controlLearn Digital Electronics by building a pump safety stop using a NAND gate. Design a circuit that cuts power to 0V only when two sensors detect a full tank.
- Practical case: Window sensor security alarmMaster Digital Electronics by building a fail-safe alarm with a NAND gate. Detect open windows and trigger a 5V LED signal instantly when security is breached.
Medium Level
- Practical case: Light switching from two pointsMaster Digital Electronics by building a 2-way switch using the universal NAND gate. Synthesize XOR logic to toggle LED states based on dual input signals.
- Practical case: Debouncing SR Latch with NANDMaster Digital Electronics by building a NAND gate SR latch to eliminate switch noise. Ensure clean signals and verify stable memory states with LEDs.
