Practical case: Standby mode indicator
Level: Basic – Understand logical inversion using a NOT gate to activate a standby LED when the main system turns off.
Practical case: DC motor control with a transistor
Level: Basic – Learn to use an NPN transistor as a switch to drive a DC motor, including the use of a flyback diode.
Practical case: Frequency divider by 2, 4 and 8
In this Digital Electronics lab, use a Binary counter to build a frequency divider. Verify square wave outputs at f/2, f/4, and f/8 relative to the clock.
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: Vault Lock with Delay and Power Drive
Master Analog Electronics by building a secure lock. Use a Transistor circuit to trigger a solenoid only when two keys turn, holding the signal for 5 seconds.
