Today Free Circuit Diagrams 4U is  going to give you a useful circuit diagram.This circuit is mainly operated by two ICs.One is NE555 and IC 4017.When you  build this circuit use a  PCB.If you use blue colour LEDs it would be so attractive. Note:-  # Don't supple over 9V  # Build this circuit on a PCB

At present most of people use LED light systems.Because LEDs can save our electricity on the other hand we can see LEDs have good life time.So that most of factories use LEDs  to make light circuits.Today Free Circuit Diagrams 4U is going to give you a simple LED driver circuit diagram.This can give a smooth current to your LED this can drive 1W LED. Note:           # Build this circuit on a PCB

This is very useful circuit for us.Because we can light up 10W Fluorescent lamp by using this circuit diagram.This circuit operates with single transformer.I suppose now you can enjoy this inverter.When you wind the transformer do it carefully because that is the heart of this circuit. Note # Be careful when you operate this circuit because high voltage is dangerous. # This circuit is not good for kids

This is so useful circuit diagram for you Because this circuit can light up an LED about 1 year with 9V battery.Here I have used famous IC HEF 4093. Note # Use a white colour LED # Build this on a PCB to get maximum result # Use 9V battery to power this circuit
