Practical case: Asynchronous Decade Counter
Build a 0-9 Binary counter in this Digital Electronics guide. Wire a 74LS93 with logic gates to trigger a reset at 1010 and track the count on LEDs.
Practical case: 4-bit up counter with LEDs
Build a practical Digital Electronics circuit with a Binary counter. Visualize the 0 to 15 sequence on LEDs and verify synchronous clock signals.
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: 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.
