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.
Thanks For Reading.
Pin 1 to ground
Pin 2 to ground
Pin 3 to resistor and LED then to ground
Pin 4 to Supply
Pin 5 to 0.1uf Capacitor then to ground
Pin 6 joined to Pin 2
Pin 7 10K resistor to Pin 6 and 47K resistor to Pin 8
Pin 8 to supply.
