CASE ANALYSIS
Scenario
Design a classic astable multivibrator using discrete BJTs to flash two LEDs alternately, useful for learning transistor switching and RC timing.
Key decisions
- Use NPN transistors with collector LEDs and cross-coupled capacitors.
- Set RC time constants for roughly 1 Hz flashing.
When to reuse this
When you need a simple, low-frequency oscillator for visual indication or timing.
