Basic LM555 Timer CIRCUIT
Part List
C2 = .01uf
IC1 = LM555 Timer
SWI = n.o. momentary switch
R1 and C1 determine lenght of
out put pulse where t = R1 x C1
and R1 is in ohms and C1 is in farads .

LED multivibrator
This is a fantastic schema because lots of beginners select this one as their first schema. by using this one you can do lots of things that means you can make pulse generators even.Here two LEDs are blinking one by one.
This can be operated by using 3v battery
parts:-
* Q1 and Q2 = C828
*C1 and C2 = 100uf
*R1 and R4= 47k
*R2 and R3= 33k
*LED=2 co lour leds
Hear if you want to add more leds you can use D400 instead of C828 then you can add leds up to 12.
