LED multivibrator

This is a fantastic circuit because lots of beginners select this one as their first circuit. 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.
