Simple 2 LED Blinking Flasher Circuit


Simple Blinking  Flasher LED circuit

This simple led flasher blinker circuit made by using two npn BC547 transistor and some resistors and capacitors.

The speed of blinking can be changed by changing the value of resistor R1 and R2. A preset of 100k should connect before the R1 and R2 for adjusting the speed of blinking the led. This led flasher circuit is very easy and simple and there is no any ic used. Use 9v or 12v battery or adaptor for this circuit.

This circuit basically works on the charging and discharging of capacitors.
