Mini Flasher

Posted on Feb 6, 2014

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
