This is a simple two led flasher circuit made by using a pair of NPN transistors(2N3904).
Just wait for 5 seconds to see the working.It works on a 9v dc battery . Charging and discharging of the capacitors control the duty cycle.
You can change the flashing rate and fade effect of the led by changing the values of the 100k resistor and 1uf capacitor.
For any question, please leave comments.
