Objective and use case.
In this session, you will build a digital safety circuit using a 74HC00 NAND gate. The circuit monitors two liquid level sensors and automatically cuts power to a «pump» (simulated by an LED) only when both sensors indicate the tank is dangerously full.
Industrial tank filling: Prevents chemical spills by ensuring redundant sensors must agree before triggering an emergency shutdown.
Sump pump systems: Prevents motor burnout or overflow by managing logic states between high-water and critical-overflow marks.
Home automation: Simple logic for reservoir management without needing a microcontroller.
