Blinking LED (Astable Mode).

How It Works:

In astable mode, the NE555 continuously switches between HIGH and LOW states, generating a square wave signal. This makes the LED blink at a set frequency.

Components Needed:

• NE555 Timer IC (1x)
• Resistors:
  • 1kΩ (1x)
  • 10kΩ (1x)
• Capacitor:
  • 10µF (electrolytic) (1x)
• LED (1x)
• Power supply (5V or 9V battery)
• Breadboard & jumper wires

How to Build:

1. Connect Power:
   • VCC (Pin 8) → 5V or 9V power supply
   • GND (Pin 1) → Ground (0V)
2. Set Up the Timing Components:
   • 1kΩ resistor (R1) between VCC (Pin 8) and Discharge (Pin 7)
   • 10kΩ resistor (R2) between Discharge (Pin 7) and Threshold (Pin 6)
   • 100µF capacitor (C1) between Threshold (Pin 6) and Ground (GND)
   • 100nF capacitor (C2) between Control (Pin 5) and Ground (GND)
   • Jumper between Threshold (Pin 6) and Trigger (Pin 2)
   • Jumper between Reset (Pin 4) and VCC (Pin 8)
3. Connect the Output:
   • LED (with 200Ω resistor) connects from Output (Pin 3) to Ground (GND)
4. Power the Circuit:
   • When powered on, the LED will blink continuously at a frequency set by R1, R2, and C1.
