⚙️ Components Used:
IC 555 Timer

Resistor (R)

Capacitor (C)

Push Button (Trigger)

LED (Output indicator)

Breadboard & Jumper Wires

Power Supply (5V–12V)

📐 Timing Formula:
T = 1.1 × R × C
👉 Example: For R = 100 kΩ, C = 10 µF → T ≈ 1.1 seconds

💡 Applications:
Pulse generation

Switch debouncing

LED or buzzer timer
