Micro Flasher

Micro Flasher

Circuit diagram with Parts list

Description.

This micro flasher circuit continuously emits flashing light with the consumption of very less power.The circuit can run for a very long time for four 1.5 V torch cells.

Here a low power CMOS IC CD4093 (IC1) is used to produce sharp pulses  of 20 ms from a red LED.The LED appears to be glowing continuously due to persistence of vision ,and lot of power is saved.The IC1 is quad NAND gate whose one gate is used for producing oscillations.The unused inputs are kept to logic 1 by connecting it to the positive.The value of R1 determines the charging current of C1.
