Practical case: Floating Inputs and Noise Sensitivity
Master Digital Electronics by building a NOT gate circuit with high impedance. Observe how weak pull-downs cause signal instability and false logic states.
NOT gate
Practical case: Empty Tank Level Indicator
Master Digital Electronics by building a water level alarm with a NOT gate. Design a circuit that lights an LED when tanks empty, preventing pump damage.
Practical case: Emergency deactivation
Learn Digital Electronics by building a safety kill switch using a NOT gate. Create a circuit where pressing a button instantly cuts the Ready signal voltage.
Practical case: Automatic darkness sensor
Master Digital Electronics by building an automatic night light. Use a NOT gate and LDR to detect darkness and trigger an LED, learning practical sensor logic.
Practical case: Open door alarm
Master Digital Electronics by building a security circuit with a NOT gate. Learn to trigger an LED warning signal instantly when a switch contact opens.
Practical case: Safety control with inverse logic
Master Digital Electronics by building an emergency stop circuit. Use a NOT gate to invert sensor signals and instantly halt a motor when a limit is reached.
