Components: Red LED, 220Ω resistor, jumper wires, power source
Steps:
Components: NE555, LED, resistors (10kΩ, 100kΩ), capacitor (10µF)
Steps:
| Issue | Solution |
|---|---|
| LED doesn't light | Check polarity (anode to +, cathode to -) |
| Circuit doesn't power | Verify power rail connections |
| IC not working | Check VCC and GND pin connections |
| 555 not oscillating | Verify threshold/trigger capacitor wiring |
| Microprocessor stuck | Check RESB is HIGH after reset pulse |
