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.
Basic
Practical case: Dual Safety Motor Activation
Learn 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 System
Master 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 control
Learn 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 alarm
Master 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.
Practical case: High power circuit isolation
Master Analog Electronics by building a Relay driver circuit. Learn to safely switch high-power loads with low-voltage signals and verify galvanic isolation.
