Introduction: Fake Alarm LED Circuit

Picture of Fake Alarm LED Circuit

Here is a Simple Flashing LED circuit which is good for bringing dummy security camera's to life or using as a Fake Alarm for cars and many other possibilities.

The speed and timing are controlled by the capacitor from pin 2 to ground.

Items needed -

555 IC

47K resistor

10K resistor

470 or 330 resistor

LED

Cables

Breadboard.

5v power supply.

Thanks For Reading.
