This circuit is a simple Clap Switch using a NE555 and two BC547 NPN Transistors in a timer configuration, able of driving a light bulb up to 230 volts!
Principle of operation: Noise is received by the microphone capsule, the circuit with NE555 comes into action driving the relay (5/6 volt relay only).. At this point the relay closes the contact and powers the 230 Volt bulb.
Components:
- 1x Microphone
- 1x NE555 IC (no NE556 or TLC555)
- 2x BC547 NPN Transistors (or equivalent)
- 2x LED 5mm (any colors)
- 1x 2Ω Resistor
- 1x 330Ω Resistor
- 1x 470Ω Resistor
- 2x 1KΩ Resistors
- 1x 3,8KΩ Resistor
- 1x 47KΩ Resistor
- 1x 100uF at 25 volt Electrolytic Capacitor
- 2x 100nF Capacitors
- 1x 1N4007 Diode
- 1x 5/6 Volt Relay
