Flashing LED Using IC555

Flashing Leds Using IC555

This simple circuit using IC555 will generate on/off signal through which we can do Led blinking . 

the Duty Cycle of the square wave is depending on R1,R2,C1 Values .

 This is kind of one channel pulse generator . If we want more than one channel to generate different square wave signals with different Duty Cycles, we can use IC4017 .
