Robo circuit Diagram ( LED )

This is a very famous circuit diagram among electronic lovers.Because we can use this circuit for various purposes. Free Circuit Diagrams 4U has given you various circuits with this circuits not only LED circuits we can use  timer circuits with this circuit diagram..This circuit diagram is called robo circuit because this circuit has used to decorate robots that is the reason of using this name.Here we have used D400 transistor and also you can extend the blinking time of the LEDs by changing the values of 100uF and 47K.

Note :

Don't supply over 6V power for the circuit diagram
