1 TRANSISTER LED FLASH AND LM 3909 LED FLASHER

Here is a one transistor LED flasher circuitwhich will flash a super bright LED. The
circuit is using single transistor as driver which is taking flash rate from the LED 2 which
is a self flashing LED. The flash rate can be adjusted by changing the value of 1k resistor
used in the circuit. The circuit is using 2N3904transistor but you can use any NPN
transistor available with you. The input power can be from any 6V DC battery or
