Practical case: Safety interlock in a chemical reactor
Master Digital Electronics by building a redundant safety interlock. Use an AND gate circuit to validate three critical inputs and activate a high-power relay.
Digital Electronics
Practical case: Simple security code validation
Master Digital Electronics by building a dual-switch security lock. Use a 74HC08 AND gate to trigger a solenoid only when two signals activate simultaneously.
Practical case: Conveyor belt start system
Master Digital Electronics by building a safety interlock circuit. Use a 74HC08 AND gate to activate a conveyor motor only when specific sensor signals align.
Practical case: Temperature and Pressure Monitoring
Master Digital Electronics by building an industrial safety circuit. Use an AND gate to trigger an alarm only when both temperature and pressure sensors spike.
Practical case: Vehicle access control with barrier
Master Digital Electronics by building a safety barrier circuit. Use a 74HC08 AND gate to trigger a 5V LED signal only when dual inputs activate simultaneously.
Practical case: Conditional automatic irrigation system
Master Digital Electronics by building a smart irrigation controller with a 74HC08 AND gate. Create a safety circuit that activates a pump only when safe.
