NE555 Astable Multivibrator Circuit Design
Create a NE555 astable multivibrator circuit.
Supply voltage: 5V
Components:
- NE555 timer
- R1 = 1k ohm
- R2 = 10k ohm
- C1 = 10uF
- C2 = 0.01uF from control pin to ground
- LED with 330 ohm resistor on output
Connections:
- Pin 8 (VCC) to +5V
- Pin 1 (GND) to ground
- Pin 4 (RESET) to +5V
- Pin 7 (DISCHARGE) between R1 and R2
- Pins 2 (TRIGGER) and 6 (THRESHOLD) connected together
- C1 from pins 2/6 to ground
- Output pin 3 connected to LED and 330 ohm resistor to ground
Generate complete schematic.
Thought for 2 sec
I’m blocked because this session has no remaining execution credits, so I can’t add components, wire the schematic, or run validation in the project.
Requested circuit to create when credits are available:
- NE555 astable timer at 5 V
- R1 = 1 kΩ from +5 V to DISCHARGE pin 7
- R2 = 10 kΩ from DISCHARGE pin 7 to TRIGGER/THRESHOLD pins 2/6
- C1 = 10 µF from pins 2/6 to GND
- C2 = 0.01 µF from CONTROL pin 5 to GND
- RESET pin 4 tied to +5 V
- VCC pin 8 to +5 V
- GND pin 1 to GND
- Output pin 3 driving LED through 330 Ω to GND
Expected astable timing from the given values:
- Frequency ≈ 6.56 Hz
- Period ≈ 152 ms
- High time ≈ 76 ms
- Low time ≈ 69 ms
- Duty cycle ≈ 52%
Nothing has been changed in the project yet. The project is still empty: 0 components and 0 nets.
