Introduction: 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 -
470 or 330 resistor
5v power supply.
