Hi every one this is 230V LED bulb circuit diagram.At the moment 230V LED bulbs have become very popular due to its low power consumption and due to it's clear light.I suppose this little circuit will be very useful circuit for you all.If you are an underage guy don't try this because 230V is so dangerous.
Note : Always use the correct values when you build this circuit

Hi friends today I have brought you some thing special.Actually this would be a very interesting topic for our vehicle lovers.Today Free Circuit Diagrams 4U is going to give you a 12V battery level indicator circuit diagram.According to the battery voltage LEDS will light up.
Note: # To get maximum result build this circuit on a pcb.
# Don't forget this is a 12V power circuit diagram

Hi every one today there is a special circuit for you .It is nothing but an inverter circuit diagram.If you supplied 12v you can get 230V as the out put current.IRFZ44t loads up to 200W ,or 350W into IRFZ48 IRF3205 Can load up to 600W.When you build this circuit always try to use quality parts.And If you are a kid don't try this circuit diagram because 230V is dangerous.When you check this wear rubber gloves.
Note : Don't try this alone.Because this circuit is very dangerous

Hi guys today We hope to give you a very simple fade circuit diagram.First of all I must say that this is a circuit for beginners.When we switch off the circuit it will take some time to switch off the light.After switching off the circuit the LED will get the power of capacitor.When the charge of the capacitor reducing we will be able to see like fading out the LED

As electronic lovers we all have to face many troubles when we check some circuits.Among them soldering matters act a major part.Sometimes we can't see those faults with our eye.Some times using multimeter is also some what difficult because we have to read the value of it but by using following circuit diagram you will be able to guess whether the connections of the circuit is ok or not..Here we have used IC 741 .This circuit is operated with 9V power.
Note : Build this circuit on a P.C.B

Already Free Circuit Diagrams 4U has given you Knight rider circuit diagrams.But most of guys asked 230V knight rider circuit.I must say that you can convert common Circuit diagram in to 110V or 230V By using a relay.Here we have do a small modification for the common Circuit diagram.enjoy this.
Note: Build this circuit on a pcb.
Always supply 6V fro the circuit diagram
To see the general Knight rider circuit diagram click here
I suppose all the vehicle lowers will love this circuit Because at present when we do a modification for a vehicle Amplifier also acts a major role.Today we are going to give you5.8W Power Amplifier Circuit Diagram.Here we have used Ic TA222AP.When you use a speaker please use a speaker according to the power of the amp.
TA7222AP pin out

Hi everyone today we have decided to give you a touch lamp circuit diagram.This circuit is operated with 12 V power.And here we have used 2N2905 ,2N3906 and 2N3055 transistors.Personally I think this is a best circuit to modify your car or van.Not only that you can attach this circuit to your motorcycle too.If you want to connect this circuit you can do that via a relay.Before this post Free Circuit Diagrams 4U has given you simple circuit diagrams Clich here to see Have a nice day.

At present we can see the temperature of this planet is increasing day by day so that the people use various types of things to overcome that matter some rich countries use air conditioners but poor countries cant use ac machines because they have to pay unbearable electricity bill.you all know Free Circuit Diagrams 4U always think about all the nations ,all the ages etc. we always try to be balance when we post something that is why we have come to this level.OK, Today we are going to give you a Automatic fan circuit .That means you can operate this circuit with 6V to 12V power.The special thing of this circuit is this circuit is switched on and off according to the temperature of the environment.Here we have used LM35 as the temperature sense sensor and BC 548 to amplify the current.

Last few days most of guys asked me.Some data sheets of various radio components.I suppose some of you also may have the same question.There are many web sites which give free data sheets so I'll give you several websites which give free Data sheets.

Today we are going to give you a simple AM transmitter circuit diagram.At the moment FREE CIRCUIT DIAGRAMS 4U has given you may transmitter circuit diagrams .Before every thing I must say that FREE CIRCUIT DIAGRAMS 4U give you these circuits to expand your knowledge not for make troubles for others.I must say that If some one misused this circuit diagram FREE CIRCUIT DIAGRAMS 4U doesn't take any responsibility of that.Here we have used two transistors 2N2904A and 2N3053. You can operate this circuit diagram with 12V.For this transmitter you have to make some what long antenna.
Note : Build this circuit on a PCB
Antenna should be 20 to 30 feet
