Description.

Here is a simple and compact flasher circuit that an be used where ever a flashing LED is needed.The circuit finds application in flashing beacons,alarms automobile and more.

The circuit is nothing but an astable multivibrator based on IC NE 555 (IC1).The frequency of the oscillation depends on the values of R1,R2 ,R3 and C2.The LED glows when the out put  (pin3)  of IC1 goes high.The  IC1 NE 555 can easily drive a LED.The resistor R4 acts as a current limiter for LED.

Notes. 

A 6V battery or 6V DC power supply can be used to power the circuit. For 6V power supply  for this circuit, Click Here!. If you don’t need frequent changes in the flashing rate use a preset for R2 and set it for the required rate.  The capacitor C2 must be rated 10V.
