    LED Flasher Using BJT

    LED Flasher
    LED flasher circuit

    The circuit is an astable multivibrator with LED connected to the collector of each of the transistor. The LEDs light up alternately at a frequency predetermined by the value of R2, R3, C1 and C2 using formula for frequency of oscillation of an astable using bjt.
